A Guide to Keeping Your Concrete Clean

Grant Cool • January 18, 2026

Your concrete driveway, patio, and walkways are some of the hardest-working surfaces on your property. They endure heavy traffic, intense sun, freezing temperatures, and everything in between. We choose concrete for its durability, but that toughness doesn't mean it's immune to getting dirty. Over time, that clean, gray surface can become marred by oil leaks, rust spots, tire marks, and general grime. A stained and dirty driveway doesn't just hurt your home’s curb appeal; it can also be a sign of deeper issues that might affect the concrete’s longevity. At Farmington Concrete, our expertise extends far beyond pouring new slabs. We are committed to helping you protect your investment by providing the solutions and guidance needed to maintain your concrete, ensuring it stays clean, safe, and beautiful for years to come.


Why Does Concrete Get So Dirty?

To effectively clean concrete, you first need to understand its nature. While it looks like a solid, impenetrable surface, concrete is actually porous. Imagine it as a very dense sponge with millions of microscopic pores and capillaries. This structure is what allows it to absorb water, but it also means it can absorb stains.


When a car leaks oil or a glass of wine spills, the liquid doesn't just sit on the surface; it seeps into these pores. Once a stain penetrates the concrete, it becomes much harder to remove. This porosity is also why moisture can get trapped, creating an ideal environment for mold and mildew to grow, especially in shaded areas. A simple spray with a garden hose might wash away surface dirt, but it often won't be enough to lift out deep-set stains.


How Farmington Concrete Helps You Tackle Tough Stains

Different stains require different chemical approaches. Using the wrong cleaner can be ineffective or, even worse, can damage the concrete itself. Our team at Farmington Concrete helps homeowners identify the best solutions for the most common and stubborn stains.


Oil and Grease Stains

These are the most frequent offenders on driveways and garage floors. Oil penetrates deeply and repels water, making it notoriously difficult to remove.

  • Our Solution: For a fresh spill, speed is everything. We recommend immediately covering the spot with an absorbent material like kitty litter, sawdust, or baking soda to soak up the oil before it sets. For older stains, a standard soap won't work. We advise using a high-quality degreaser or an enzymatic cleaner that is designed to break down the oil at a molecular level. For the toughest stains, we can guide you on using a poultice that pulls the embedded oil out of the concrete’s pores.


Rust Stains

Orange streaks from metal patio furniture, old tools left in the rain, or even certain lawn fertilizers can spoil the look of your concrete surfaces.

  • Our Solution: Rust removal typically requires an acid-based cleaner to dissolve the iron oxide. However, acids can be hazardous and can etch the concrete surface if not used correctly. We help you find effective rust removers that are safe for concrete and provide clear instructions on the proper application technique to remove the stain without creating new damage.


Mold, Mildew, and Algae

In damp or shaded parts of your property, concrete can develop green or black patches of organic growth. This is not only unsightly but also creates a significant slip hazard, especially when wet or icy.

  • Our Solution: While a pressure washer is a good first step, it often only removes the surface layer of mold, leaving the spores behind to regrow. We recommend specialized cleaners designed to kill the growth at its root, preventing it from returning quickly. We also advise on products that are safe for your surrounding lawn and garden.


The Best Defense: Protective Concrete Sealants

The most effective way to deal with a stain is to prevent it from ever happening. That’s where sealing comes in. At Farmington Concrete, we consider sealing to be the single most important maintenance step you can take to protect your exterior concrete. A quality sealer works by filling or covering the pores in the concrete, creating a protective barrier that stops liquids and dirt from penetrating. When concrete is properly sealed, spills will bead up on the surface instead of soaking in, giving you time to wipe them away before they can cause a permanent stain. A good sealer also protects against damage from the freeze-thaw cycles common in our climate.


Choosing the Right Sealer

We help you choose the best product for your specific needs:

  • Penetrating Sealers: These soak into the concrete to protect it from within. They do not change the look or texture of the surface, making them an excellent choice for driveways and walkways where maintaining good traction is a priority.
  • Film-Forming Sealers: These create a durable film on top of the concrete. They are often used for decorative or stamped concrete, as they can enhance the color and add a satin or gloss finish.

Applying a sealer correctly is crucial for its performance. We provide expert advice on surface preparation and application to ensure you get a professional result that will last for years.


Simple Tips for Regular Upkeep

A little routine maintenance goes a long way in keeping your concrete looking its best and extending the life of its protective seal.

  1. Sweep Regularly: Dirt, leaves, and other debris can trap moisture against the concrete, which can lead to staining and mildew growth. A quick sweep once a week can make a big difference.
  2. Clean Spills Quickly: Even sealed concrete can stain if a spill is left for too long. Clean up oil, grease, or other chemicals as soon as you notice them.
  3. Be Careful with De-Icers: During Farmington’s winters, avoid using rock salt or other harsh chemical de-icers, as they can cause the surface of the concrete to pit and flake (spall). Sand or cat litter are safer alternatives for traction.
  4. Know When to Reseal: Sealers don't last forever. Depending on sun exposure and traffic, most sealers need to be reapplied every 2 to 5 years. A good test is to splash some water on the surface; if it darkens and soaks in instead of beading up, it’s time to reseal.

Wet concrete coming out of a pipe
By Grant Cool February 27, 2026
When you're planning a home improvement project or a commercial build, the materials you choose set the stage for everything that follows. You might be dreaming of a sleek new driveway, a sturdy foundation for an addition, or a decorative patio for summer barbecues. In almost every scenario, concrete is a top contender. It’s the second most used substance on Earth after water, and for good reason. But is it the right choice for your specific project? At Farmington Concrete, we believe that an educated customer is our best partner. We don't just want to pour your concrete; we want you to understand exactly what you are investing in. Like any building material, concrete has its strengths and its weaknesses. Understanding these trade-offs is crucial to ensuring you are happy with the result not just tomorrow, but twenty years from now. What Makes Up Concrete? Before weighing the pros and cons, it's important to understand what concrete actually is. Concrete is a composite material made up of several key ingredients, each playing a vital role in its strength and durability: Cement: Often referred to as Portland cement, this fine powder acts as the binder, holding everything together. When mixed with water, it triggers a chemical reaction called hydration, forming a strong, stone-like material. Aggregates: These are small and large particles, usually a combination of sand (fine aggregate) and gravel or crushed stone (coarse aggregate). Aggregates make up about 60% to 75% of the total mix, giving concrete its body and much of its strength. Water: Essential for the chemical reaction with cement, water activates the hardening process and ensures the mixture is workable. Admixtures (optional): Sometimes, additional chemicals are added to modify certain properties of the concrete, such as curing time, resistance to freezing, or improved workability. When these components are properly mixed and poured, they create a material that is both tough and long-lasting. The balance between cement, water, and aggregates is crucial; too much water can weaken the slab, while too little may make it unworkable or prone to cracks. In short, concrete's durability and popularity come from this careful combination of simple yet effective ingredients, making it suitable for a wide range of building projects. In this guide, we’ll strip away the industry jargon and give you an honest, transparent look at the pros and cons of concrete, helping you decide if it’s the perfect fit for your next project. The Heavyweights: The Advantages of Concrete Let’s start with why concrete has been the backbone of infrastructure since the Roman Empire. There is a reason we still see structures standing today that were built thousands of years ago. 1. Unmatched Durability and Strength If you want something to last, concrete is the gold standard. It is incredibly strong, capable of withstanding immense weight and pressure. This makes it ideal for driveways that hold heavy vehicles, foundations that support entire houses, and commercial floors that see constant foot traffic. Unlike asphalt, which softens in the summer heat and can be easily damaged, concrete remains rigid and strong. It doesn't rot like wood, rust like metal, or deteriorate quickly under UV exposure. A well-poured concrete driveway or patio can easily last 30 to 50 years or more. When you calculate the cost per year of lifespan, concrete is often the most economical choice because you aren't replacing it every decade. 2. Low Maintenance Requirements We know you have better things to do on a Saturday than maintaining your driveway. Wood decks require annual staining and sealing to prevent rot. Asphalt driveways need regular resealing to stop them from crumbling. Concrete? It asks for very little. Once it cures and is properly sealed, concrete is virtually maintenance-free. A simple sweep to remove leaves and debris, and perhaps an occasional pressure wash to remove dirt or oil stains, is usually all that is required to keep it looking pristine. This "set it and forget it" nature is a huge selling point for busy homeowners and business owners in Farmington. 3. Incredible Versatility and Aesthetics Gone are the days when concrete just meant a boring, grey slab. Today, concrete is a chameleon. It can be shaped, textured, and colored to mimic much more expensive materials. Stamped Concrete: We can stamp patterns into wet concrete to make it look like brick, slate, flagstone, or even wood planks. Stained Concrete: Acid stains and water-based dyes can transform standard grey concrete into rich, earth-toned surfaces that look like marble or leather. Polished Concrete: For interiors, we can grind and polish concrete until it shines like glass, creating a modern, industrial-chic floor that is incredibly durable. This versatility means you can get the high-end look of stone or pavers without the high-end price tag or the maintenance issues of weeds growing between the cracks. 4. Energy Efficiency (Thermal Mass) Concrete has high thermal mass, meaning it absorbs and stores heat energy. In a home, concrete floors can absorb heat from the sun during the day and release it slowly at night, helping to regulate indoor temperatures. This can actually lower your heating and cooling bills over time, making it a smart choice for energy-conscious builds. The Hard Truths: The Disadvantages of Concrete At Farmington Concrete, we value honesty. Concrete is amazing, but it isn't magic. There are potential downsides that you need to be aware of before committing to a pour. 1. Higher Upfront Cost There is no getting around it: concrete is an investment. It is generally more expensive to install than asphalt, gravel, or some wood decking options. The cost comes from several factors: Materials: Cement production is energy-intensive, and the cost of quality aggregates adds up. Labor: Preparing the site—grading the soil, building forms, and installing reinforcement—takes skilled labor and time. Finishing: Achieving a professional finish requires experienced craftsmen who know exactly when to float, trowel, and broom the surface. However, it is important to view this cost in context. While the initial price tag is higher, the long lifespan and low maintenance often make concrete cheaper in the long run. 2. Potential for Cracking This is the most common concern we hear, and it is a valid one. Concrete is rigid. Unlike asphalt, which is somewhat flexible, concrete cannot bend. If the ground underneath it shifts, or if the concrete shrinks too much during the curing process, it can crack. There is an old saying in our industry: "There are two guarantees with concrete: it will get hard, and it will crack." While we cannot guarantee a crack-free surface 100% of the time, professional installation mitigates this risk significantly. We use control joints (planned cuts in the slab) to encourage the concrete to crack in straight, invisible lines rather than random spiderwebs. We also use steel reinforcement (rebar or wire mesh) to hold the slab together tightly if a crack does occur. 3. Hardness and Unforgiving Nature The same quality that makes concrete durable—its hardness—can also be a drawback depending on the application. Comfort: Standing on a concrete floor all day can be tough on your joints and back. If you use concrete for interior floors, you might need area rugs or anti-fatigue mats in places where you stand often, like the kitchen. Safety: If a child falls on a concrete patio, they are more likely to get a scraped knee than if they fell on wood or grass. Fragility of Objects: If you drop a glass or a plate on a concrete floor, it will almost certainly shatter. 4. Difficulty of Repairs If concrete does sustain significant damage—like heaving from a tree root or severe salt damage in winter—it is harder to patch than other materials. You can't just replace a single "board" like you can with a deck. Often, repairing concrete involves resurfacing the entire area or cutting out and re-pouring a section, which can result in a visible difference in color between the old and new concrete. How Farmington Concrete Tips the Scales in Your Favor Knowing the pros and cons is step one. Step two is choosing a contractor who knows how to maximize the pros and minimize the cons. This is where Farmington Concrete makes the difference. You cannot buy a bag of mix at the hardware store and expect the same results as a professional crew. We bring scientific precision and years of local experience to your project. Professional Site Preparation The number one cause of concrete failure isn't the concrete itself; it's the ground underneath it. If the soil is loose or poorly drained, the slab will settle and crack. We don't cut corners on prep work. We spend considerable time excavating soft soil, installing a proper gravel base, and compacting it thoroughly. This creates a stable foundation that drastically reduces the risk of settling and cracking. Custom Mix Designs We don't just order "concrete." We specify the mix based on your project. A driveway holding heavy trucks needs a different compressive strength (PSI) than a backyard patio. We ensure the mix is perfectly suited to the local Farmington climate, using the right amount of air entrainment to withstand freeze-thaw cycles. Expert Finishing and Curing The difference between a DIY job and a pro job is often in the finish. Whether you want a non-slip broom finish for safety or a high-gloss stamped finish for elegance, our craftsmen have the tools and experience to manipulate the surface perfectly before it sets. Furthermore, we apply high-quality sealers that protect the concrete from moisture, stains, and UV damage, extending its life and beauty. Making the Right Choice Concrete is a commitment. It’s a permanent addition to your property that will likely outlast your time in the home. It offers strength, beauty, and value, but it demands respect and expertise to install correctly. By understanding the trade-offs , you can make a decision that fits your budget, your aesthetic, and your lifestyle. If you value longevity and low maintenance, and you view your home as a long-term investment, concrete is almost always the superior choice. Don't leave your project to chance. Work with a team that is transparent about the materials and dedicated to the craft. Ready to discuss your project with honest experts?

Drainage and controlling your water flow
By Grant Cool February 20, 2026
Water is a homeowner's most persistent foe. A soggy lawn turns into a muddy swamp. Puddles on the driveway become treacherous ice sheets in the winter. Worst of all, water pooling against your foundation can lead to devastating cracks, basement leaks, and costly structural damage. Many in Farmington have learned this the hard way, battling drainage issues with temporary fixes that never seem to last. You might have tried digging a shallow trench or adding more gravel, only to see the problem return after the next big rainstorm. These solutions often fail because they are susceptible to clogging with silt and debris. The real, permanent answer to your water woes is often the most durable material in construction: concrete. When expertly installed, concrete is more than just a building material; it's a powerful tool for water management . At Farmington Concrete, we do more than just pour patios and driveways. We design and install intelligent hardscape systems that actively protect your home by controlling water. This guide will explain how concrete can solve your drainage problems for good and why it's the most effective, low-maintenance choice for your property. The High Cost of Uncontrolled Water Before we look at the solutions, it's vital to understand the damage that poor drainage can cause. Water always follows the path of least resistance. If you don't provide a clear path for it, water will carve its own, often through the most vulnerable parts of your home. Foundation Damage: This is the most serious threat. Water saturating the soil around your foundation creates immense hydrostatic pressure. This force can bow foundation walls, cause cracks to form, and lead to chronic basement flooding and mold growth. Landscape Erosion: Uncontrolled runoff from your roof or other hard surfaces can strip away topsoil and mulch, destroying your garden beds and leaving behind ugly, eroded gullies. Safety Hazards: Standing water on walkways and driveways is a major slip-and-fall risk. During Farmington's winters, these puddles freeze into dangerous sheets of ice, creating a liability hazard for your family and visitors. Pest Problems: A yard with standing water is a perfect breeding ground for mosquitoes and other unwanted pests. While a French drain filled with gravel might seem like an easy fix, it's a temporary one. Over time, soil and debris inevitably wash into the gravel, clogging the system and making it useless. Concrete, however, offers a solid, permanent solution that works year after year. How Farmington Concrete Solves Drainage Issues Concrete’s unique combination of strength, precision, and versatility makes it the superior choice for managing water on your property. Our team utilizes several key techniques to transform a water problem into a water solution. 1. The Power of a Perfect Slope The simplest and most effective drainage tool is gravity. The key is to create a surface that guides water precisely where you want it to go. This is where professional concrete installation makes all the difference. When we pour a new driveway, patio, or walkway, we aren't just making it flat. We use laser levels and precise calculations to engineer a subtle, almost imperceptible slope—typically a 1% to 2% grade. This means the surface drops one to two feet over a distance of 100 feet. This gentle angle is all it takes to ensure rainwater sheets off the surface and flows away from your home's foundation, directing it toward the street or a designated drainage area. A DIY patio that slopes toward your house is far worse than no patio at all. We guarantee every surface we install actively works to keep your home dry. 2. Concrete Swales and Drainage Channels For properties with more significant water issues, such as runoff from a neighbor's yard or a naturally low spot in the lawn, a simple slope may not be enough. In these situations, we design and install custom concrete drainage channels, also known as swales or flumes. A concrete swale is a wide, shallow trough designed to capture, control, and redirect large volumes of water. Think of it as a permanent, maintenance-free riverbed for your property. We can install them along property lines to intercept water flow or strategically across a lawn to solve areas that constantly flood. Unlike a grassy swale that erodes or a gravel drain that clogs, a concrete channel provides a smooth, solid, and predictable path for water. It's incredibly easy to clean with a leaf blower or hose and will perform its job flawlessly for decades. 3. Permeable Concrete: An Innovative Approach One of the most exciting advancements in our industry is permeable concrete. While it looks very similar to a standard concrete surface, its engineering is completely different. The mix is designed to create a network of interconnected voids within the slab. When it rains on a permeable concrete surface, the water doesn't run off. It flows directly through it. The water passes through the pavement and into a sub-base of clean, open-graded stone below. This stone layer acts as a temporary reservoir, holding the water before allowing it to percolate slowly and naturally back into the soil. This technology is a game-changer for water management: Eliminates Runoff: It dramatically reduces the volume of stormwater leaving your property, which helps prevent erosion and eases the burden on municipal storm sewers. Recharges Groundwater: By returning rainwater to the soil, it helps replenish the natural water table. Meets Regulations: As environmental concerns grow, many municipalities are encouraging or even requiring permeable surfaces to manage stormwater effectively. Permeable concrete is an outstanding choice for driveways, patios, and walkways, providing the strength of traditional concrete while functioning like a natural drainage field. Why Concrete is the Superior Choice When considering drainage solutions, you have options. But concrete consistently outperforms other materials in durability, maintenance, and effectiveness. Durability: Concrete doesn't rot, rust, or decay. A professionally installed concrete drainage system will outlast any plastic or metal alternative by decades. It can handle vehicle traffic, heavy snow, and freeze-thaw cycles without breaking down. Low Maintenance: A concrete swale is virtually maintenance-free. There are no pipes to clog or filters to clean. A quick sweep to remove leaves is all you’ll ever need to do. Effectiveness: The non-porous surface and precise grading of traditional concrete give you absolute control over water flow. You decide exactly where the water goes, every single time it rains. Aesthetic Integration: We can design concrete drainage solutions that blend beautifully with your existing landscape and hardscapes. Whether you prefer a simple broom finish or an elegant stamped pattern, the drainage feature becomes an integrated part of your design, not an eyesore. Farmington Concrete: Your Partner in Water Management Solving a drainage problem requires more than just pouring concrete; it demands a deep understanding of grading, water dynamics, and local soil conditions. When you work with Farmington Concrete, you're not just hiring a contractor—you're partnering with a team of problem-solvers. Our process always starts with a comprehensive site evaluation. We analyze the topography of your property, identify the sources of water, and determine the safest and most effective strategy for managing it. We then design a custom solution tailored to your specific needs, whether it's a perfectly graded driveway, a strategically placed swale, or a modern permeable patio. Don't let poor drainage diminish the value and safety of your home. A professionally designed concrete solution is a permanent, effective, and surprisingly elegant way to solve your water woes for good. Ready to stop fighting water and start directing it?

Understanding what PSI means
By Grant Cool February 13, 2026
Stroll down the aisle of your local hardware store in Farmington, and you will see pallets stacked high with heavy paper bags. They all look similar—gray dust in thick packaging—but printed boldly on the front of each bag is a number: 3000, 4000, 5000, or perhaps something even higher. Next to it, you’ll spot the acronym "PSI." For the average homeowner planning a weekend DIY project, these numbers can be confusing. Is a higher number always better? Is the cheapest bag sufficient for a driveway? Does it really matter what you choose for a simple fence post? At Farmington Concrete, we believe that an informed customer is a satisfied customer. Understanding the materials you are working with is the first step toward building something that lasts. That number on the bag isn't just a suggestion; it is a critical rating that predicts the longevity and safety of your project. In this guide, we will demystify the technical jargon, explain what PSI really means , and show you how Farmington Concrete helps you make the right choice for a solid foundation. What is PSI? The Science of Strength PSI stands for Pounds per Square Inch . In the construction industry, this is the standard unit of measurement for compressive strength. Simply put, it measures how much weight or pressure a set block of concrete can withstand before it cracks or crumbles. Imagine a single square inch of concrete—about the size of a postage stamp. If a bag is rated at 4000 PSI, that tiny square can support 4,000 pounds of direct vertical pressure without failing. To put that in perspective, that is roughly the weight of a standard mid-size sedan resting on an area smaller than a golf ball. It is important to understand that concrete doesn't reach this strength immediately. When you first pour it, it is a liquid. As it cures (hardens), it gains strength. 7 Days: Concrete typically reaches about 70% of its potential strength. 28 Days: This is the industry standard. The PSI rating on the bag refers to the minimum strength the concrete will achieve after curing for a full 28 days. Why Does PSI Matter for Your Home? You might be wondering, "I’m just building a patio for a barbecue grill. Do I really need concrete that can hold up a truck?" The answer is almost always yes. PSI isn't just about load-bearing capacity; it is a universal indicator of quality, density, and resistance to the elements. 1. Surviving the Freeze-Thaw Cycle Living in Farmington means dealing with seasonal weather changes. The freeze-thaw cycle is one of the most destructive forces for outdoor masonry. When water seeps into the microscopic pores of concrete and freezes, it expands, creating internal pressure that causes flaking (spalling) and cracking. Higher PSI concrete typically contains more cement and less sand, making it denser. A denser mix is less permeable to water. Therefore, a 4000 PSI slab will naturally resist winter damage far better than a 2500 PSI slab, regardless of how much weight is sitting on top of it. 2. Resistance to Wear and Tear Your concrete surfaces take a beating. Driveways suffer abrasion from tires; walkways deal with foot traffic, skateboards, and snow shovels. Lower PSI concrete is "softer" and more prone to dusting or wearing down over time. Higher PSI mixes provide a harder, more durable surface that resists abrasion, keeping your finish looking pristine for years. 3. Preventing Structural Failure For projects that do carry weight, selecting the correct PSI is non-negotiable. If you park a heavy RV or a dually truck on a driveway poured with low-strength concrete meant for a sidewalk, the slab will eventually snap. The internal structure simply isn't robust enough to distribute that concentrated load. Matching the Number to the Project At Farmington Concrete, we help our clients match the mix to the mission. Generally, residential concrete projects fall into three categories of strength. General Purpose (2,500 – 3,000 PSI) This is your economy-grade concrete. It is cost-effective and easy to mix, but it is not designed for heavy loads or severe weather exposure. Best Uses: Setting fence posts, securing mailbox posts, or creating small pads for trash cans. Why: These applications usually involve burying the concrete (footings), where surface finish and freeze-thaw resistance are less critical. Standard Residential (3,500 – 4,000 PSI) This is the gold standard for most home improvement projects. It offers excellent durability and a smooth finish without breaking the bank. Best Uses: Driveways, sidewalks, patios, garage floors, and hot tub foundations. Why: These surfaces need to support vehicle traffic and withstand the elements. The higher cement content ensures a creamy finish that looks great and resists flaking. High-Performance (5,000+ PSI) This is heavy-duty material, often used in commercial or industrial settings, but available for homeowners who want the absolute best. Best Uses: Heavy equipment workshops, RV pads, countertops, and projects in areas with severe weather conditions. Why: This concrete is incredibly dense and nearly impervious to water. It sets up faster and is harder to work with, but once cured, it is virtually indestructible. The Hidden Danger: The Water Factor There is one crucial caveat that Farmington Concrete shares with every DIYer: The PSI rating is only accurate if you mix it correctly. The number one mistake homeowners make is adding too much water. Concrete is a chemical recipe. The cement needs a precise amount of water to activate. Adding extra water to make the mix "soupier" and easier to pour spreads out the aggregate particles. As that excess water evaporates, it leaves behind air pockets. Adding just one extra quart of water to a bag can slash the strength by up to 40%. That premium 4000 PSI bag you bought could turn into a weak 2400 PSI slab simply because you wanted it to flow faster. How Farmington Concrete Ensures Quality Knowing the theory is one thing; executing a perfect pour is another. That is where we come in. When you hire Farmington Concrete, you aren't just paying for labor; you are investing in technical expertise that protects your property value. We Assess Your Needs We don't guess. We look at what you are building. If you are installing a basketball court, we know you need a specific mix that offers a smooth finish and decent rebound. If you are pouring a foundation for a heavy shed, we calculate the load requirements to ensure you get the right strength. We Control the Mix Whether we are mixing on-site or ordering a truck, we rigorously monitor the water-to-cement ratio. We ensure the concrete is workable enough to finish beautifully but dry enough to maintain its maximum rated strength. We never dilute quality for the sake of speed. We Reinforce for Longevity PSI measures compressive strength (pushing down), but concrete is naturally weak in tensile strength (pulling apart). We combine the correct PSI concrete with steel rebar or wire mesh. This creates a composite material that resists cracking from shifting soil or temperature changes. Build It Right the First Time Concrete is permanent. If you pour a driveway with the wrong mix and it cracks within two years, the cost to rip it out and replace it is astronomical compared to doing it right the first time. Don't gamble your home’s foundation on a guess. Let the experts at Farmington Concrete help you navigate the numbers and choose the perfect solution for your project.
