From the beginning Ryan was on it! When I first searched yelp for help with fixing my glass block windows, lentals, and repointing on my brick outside my house he was one of the first to contact me. He scheduled to meet with me fairly quickly, was on time and realistic with what work was needed to be done and offered it at a very reasonable price. He kept me informed the whole time on everything he was doing and ensured me the job would be done correctly. Would recommend.

Our Concrete Repair Service

Our concrete repair service begins with a thorough inspection and diagnosis of the damaged concrete. We do not just look at the surface problem; we investigate to determine the root cause. This could be water intrusion, soil settlement, freeze thaw damage, or improper installation. Our expert will assess the extent of the damage to your driveway, sidewalk, patio, or foundation. Understanding the cause is critical for recommending a repair that will last. We explain our findings to you and discuss the most effective repair options for your specific situation and budget. You will receive a clear, honest assessment and a detailed estimate.

For cracked concrete, we offer professional crack sealing and repair services. We begin by cleaning out the crack, removing any dirt, debris, or loose concrete. Depending on the size and nature of the crack, we use different repair methods. For smaller, non-structural cracks, we may use a high quality, flexible polyurethane sealant that prevents water from getting into the crack and causing further damage. For larger structural cracks, we can use epoxy injection techniques that not only seal the crack but also structurally bond the concrete back together, restoring its strength. Our methods ensure a durable and weather resistant repair.

When the surface of the concrete is flaking, pitting, or spalling, we can restore it through resurfacing. This process involves first preparing the existing concrete by grinding the surface to remove the damaged layer and create a profile for the new material to bond to. We then apply a thin layer of a polymer modified cementitious overlay. This new surface is strong, durable, and can be finished with a variety of textures and colors. Resurfacing is an excellent, cost effective way to make an old, worn out concrete surface look brand new again without the cost of complete replacement. It is a perfect solution for spalled driveways or patios.

For concrete slabs that have settled or sunken, such as sidewalks, driveways, or patios, we offer concrete leveling and lifting services. One common method is slab jacking, where we drill small, strategic holes in the sunken slab. We then pump a specialized grout or polyurethane foam mixture underneath the slab. This material fills any voids in the soil below and hydraulically lifts the concrete slab back to its original, level position. This method is much faster, cleaner, and more affordable than tearing out and replacing the entire slab. It also addresses the underlying issue of poor soil support.

If a section of concrete is too damaged to be repaired through other methods, we can perform a partial replacement. This involves cutting out the damaged section of concrete with precision saws. We then remove the old concrete and prepare the sub-base underneath. New reinforcement is installed as needed, and we pour new concrete into the cutout area. We take care to match the finish of the new concrete as closely as possible to the surrounding existing concrete. This targeted approach allows us to fix severely damaged areas without the expense of replacing the entire slab.

Regardless of the repair method used, we always apply a protective sealer as a final step. After a crack is filled, a surface is resurfaced, or a slab is leveled, sealing the concrete is crucial for long term durability. The sealer penetrates the concrete and creates a protective barrier on the surface. This barrier helps to prevent water, oil, and de-icing salts from penetrating the concrete and causing future damage. Sealing is a simple but effective step that can significantly extend the life of your concrete and the repair we have performed. It also makes the surface easier to clean.

Our commitment to a 5 star service means we ensure a professional experience from start to finish. Our crews work carefully to protect your property and landscaping during the repair process. We maintain a clean and organized job site. Upon completion of the repair, we thoroughly clean the area and remove all debris. We will walk you through the completed work to ensure you are fully satisfied with the results. Our goal is to provide a durable, high quality repair that restores the safety and beauty of your concrete surfaces. We stand behind our work with a commitment to quality and customer satisfaction.

A Homeowner’s Guide On Concrete Repair in Pittsburgh

As a Pittsburgh homeowner, it is important to address concrete problems early before they become larger, more expensive issues. Our harsh freeze thaw cycles are the primary cause of concrete damage in this region. Water gets into small cracks, freezes, expands, and breaks the concrete apart over time. This leads to spalling and larger cracks. Another common issue is soil settlement, which can cause sidewalk sections to become uneven tripping hazards. When you see a crack or a settled slab, do not ignore it. A simple crack sealing today can prevent a major replacement project in a few years. When hiring a repair contractor, ensure they understand how to address the root cause of the problem, not just patch the surface.

Common Concrete Repair Questions

Damaged concrete can detract from your home’s curb appeal and pose a safety risk. Fortunately, most concrete problems can be repaired effectively, saving you the cost of full replacement. Homeowners in Pittsburgh often have questions about the process and possibilities of concrete repair. Here are answers to some of the most common questions we encounter.

The decision to repair or replace damaged concrete depends on several factors, with the most important being the extent and nature of the damage. If the damage is primarily cosmetic or localized, repair is almost always the better option. This includes issues like surface spalling, small to medium sized cracks, or minor pitting. These problems can typically be fixed effectively with resurfacing or specialized crack fillers. If a single section of a sidewalk or driveway has settled, concrete lifting is a far more economical solution than replacing the entire thing. As long as the majority of the concrete slab is structurally sound, repair is the most cost effective approach.

Replacement becomes necessary when the concrete has reached the end of its functional life and is no longer structurally sound. Signs that replacement may be needed include widespread, deep cracks that form a web like pattern, often called alligator cracking. If the concrete is crumbling and deteriorating throughout the slab, it indicates a problem with the original concrete mix or installation that cannot be fixed with a surface repair. If there are major heaving and settlement issues caused by a serious underlying problem like expansive soil or a sinkhole, a full replacement with proper subgrade engineering may be the only solution.

Another consideration is the age and overall condition of the concrete. If a 40 year old driveway has numerous problems and is nearing the end of its expected lifespan, investing in a series of repairs might not be the best long term value. In this case, it might be more prudent to invest that money in a brand new driveway that will last for another several decades. An experienced concrete professional from RMK Services can perform a thorough evaluation of your concrete and give you an honest recommendation on whether repair or replacement is the best option for your specific situation and long term goals.

Concrete resurfacing is a process used to restore the top layer of an existing concrete slab that is worn, spalled, or has minor cosmetic damage. It involves applying a thin, cementitious overlay to the top of the concrete to create a brand new, durable surface. This is an excellent way to make old, ugly concrete look new again without having to go through the expensive and disruptive process of tearing it out and replacing it. It is a cost effective solution for revitalizing driveways, patios, pool decks, and garage floors.

The process begins with thorough surface preparation, which is the most critical step. The existing concrete must be rigorously cleaned to remove any dirt, oil, sealers, or other contaminants. Then, the surface is mechanically profiled, usually with a concrete grinder. This step removes the weak, damaged top layer of concrete and creates a rough, porous surface for the new overlay to bond to securely. Any cracks or deeper damage are also repaired at this stage. Proper preparation is essential for the longevity of the resurfacing project.

Once the surface is prepared, the overlay material is mixed and applied. This material is a special blend of cement, sand, and polymer modifiers that make it very strong, durable, and able to bond tenaciously to the old concrete. The overlay can be applied with a squeegee or trowel and can be finished in a variety of ways. It can be given a simple broom finish for traction, or it can be stamped, stained, or colored to create a highly decorative look. The result is a brand new surface that is often stronger and more resistant to future damage than the original concrete was.

Concrete cracks for a variety of reasons, but one of the most common is drying shrinkage. Concrete is mixed with water, and as the slab cures and that water evaporates, the concrete’s volume shrinks slightly. This shrinkage creates tensile stress within the slab. Since concrete is weak in tension, it often relieves this stress by forming small hairline cracks. These types of cracks are very common and are usually not structurally significant. Professional installers use control joints to encourage these shrinkage cracks to occur in straight, predetermined lines.

External forces and environmental factors are another major cause of cracking. In Pittsburgh, the freeze thaw cycle is a primary culprit. Water penetrates the pores of the concrete, and when it freezes in the winter, it expands with immense force, breaking the concrete apart from the inside out. This leads to cracks and surface spalling. The settlement of the ground beneath the slab can also cause cracking. If the subgrade was not compacted properly before the concrete was poured, it can settle unevenly, causing the slab above it to bend and crack under its own weight.

Overloading the concrete slab can also cause it to crack. While concrete is very strong, it has its limits. Parking a very heavy vehicle, like a large commercial truck or an RV, on a standard residential driveway can cause it to crack. Tree roots growing underneath a sidewalk or patio can also exert enough upward pressure to lift and crack the concrete. Finally, premature drying during the curing process can also lead to a weak surface that is prone to cracking. A professional installation that addresses all of these factors is the best way to prevent most types of cracking.

Spalling is a common type of concrete damage where the top surface of the concrete flakes, peels, or chips away. It often starts as small patches but can grow to cover a large area, exposing the rough aggregate underneath and creating a pitted, unsightly appearance. Spalling not only looks bad but also weakens the concrete surface, making it more susceptible to further damage. It is a sign that the surface layer of the concrete has lost its integrity and is deteriorating.

The most common cause of spalling, especially in our climate, is the freeze thaw cycle combined with water intrusion. Water soaks into the top layer of the concrete. When the temperature drops below freezing, this water turns to ice and expands, popping off the surface layer of the concrete. The use of de-icing salts can accelerate this process significantly. Other causes of spalling can include a poor concrete mix with too much water, improper finishing techniques that trap water at the surface, or a fire that causes rapid heating and cooling of the surface.

Yes, spalling can be fixed very effectively, typically through resurfacing. The repair process involves grinding down the concrete surface to remove all the weak and spalled material. This step is crucial to get to a solid concrete base. After the surface is prepared, any deep pits or holes are patched with a specialized repair mortar. Then, a polymer modified concrete overlay is applied over the entire surface. This new layer bonds to the old concrete and creates a new, strong, and durable surface that is resistant to future spalling. This process can make a heavily spalled driveway or patio look brand new again.

Concrete leveling, also known as slab jacking or mudjacking, is a repair technique used to lift and stabilize sunken or settled concrete slabs. It is a common and highly effective solution for uneven sidewalks, driveways, patios, and garage floors that have become tripping hazards. Instead of demolishing and replacing the slab, this process lifts the existing concrete back into its correct position. It is a much faster, cleaner, and more affordable alternative to replacement.

The traditional slab jacking process involves drilling a pattern of small holes, typically about one to two inches in diameter, through the sunken concrete slab. A specialized grout mixture, often a mix of sand, cement, and other materials, is then pumped under pressure through these holes. This slurry fills any voids or empty spaces in the soil beneath the slab and then hydraulically lifts the concrete. The crew carefully monitors the process to ensure the slab is lifted gradually and evenly until it is level with the adjacent surfaces.

A more modern version of this technique uses high density polyurethane foam instead of a cementitious grout. The process is similar, but the holes drilled are much smaller, often less than an inch. The two part polyurethane foam is injected as a liquid, and it rapidly expands with incredible force, filling voids and lifting the concrete. The foam cures quickly and is very strong, lightweight, and waterproof, which helps to prevent future erosion of the soil underneath. Both methods are effective at correcting settled concrete and eliminating dangerous trip hazards, and a professional can recommend the best method for your situation.

In the vast majority of cases, it is significantly cheaper to repair concrete than it is to replace it. The cost of full replacement is high because it is a very labor intensive process. It involves demolishing and breaking up the old concrete, hauling away all the heavy debris, preparing the subgrade again, building new formwork, installing reinforcement, and then pouring and finishing a large amount of new concrete. Each of these steps requires significant labor, equipment, and material costs.

Concrete repair techniques, on the other hand, are much less invasive and require fewer materials. For example, lifting a sunken sidewalk slab using polyurethane foam injection can often be done for a third of the cost of replacing that same section of sidewalk. Similarly, resurfacing a spalled driveway is typically much more affordable than a complete tear out and replacement. Repairing concrete also saves a significant amount of time. A slab jacking repair can often be completed in a few hours, and the surface is ready for use almost immediately, whereas a full replacement can take several days and requires a long curing time.

While repair is usually the more economical option, it is important to consider the long term value. If a slab is so severely damaged that a repair would only be a short term, bandage solution, then replacement might be the more cost effective choice in the long run. However, for most common concrete problems like settlement, surface damage, and cracking, modern repair techniques offer a durable and lasting solution that provides excellent value. A professional estimate from RMK Services can give you a clear comparison of the costs for both options for your specific project.

Repairing a large crack in a driveway properly requires more than just filling it with a caulk from a tube. A professional repair is a multi step process designed to create a durable and water resistant seal. The first step is to prepare the crack. We use a diamond blade saw or a grinder to chase the crack, which means widening it slightly and creating clean, solid edges. This removes any weak, crumbling concrete from the edges of the crack and creates a uniform channel for the repair material to bond to.

After the crack has been cut and shaped, it must be thoroughly cleaned. We use high pressure air to blow out all the dust, dirt, and debris from inside the crack. The crack must be completely clean and dry for the repair material to adhere properly. Any moisture or dust left in the crack can compromise the bond and lead to premature failure of the repair. This cleaning step is simple but absolutely essential for a successful and long lasting repair.

Once the crack is prepared and clean, we fill it with a professional grade repair material. For large, non-moving cracks, we may use a high strength epoxy or polymer modified cementitious mortar. For cracks that may experience some movement, such as at a joint, we use a flexible but durable polyurethane sealant. The material is carefully applied to slightly overfill the crack. Before it fully cures, the excess material is smoothed and scraped flush with the driveway surface to create a neat, level repair. This professional approach ensures the crack is sealed from water and the repair will last for many years.

Yes, crumbling concrete, a condition known as raveling or deterioration, can often be fixed, provided the problem is limited to the surface layer and the main body of the slab is still solid. This type of damage is common on older concrete that has been exposed to years of weather and traffic. The repair method for crumbling concrete is typically resurfacing. This process removes the weak, crumbling top layer and replaces it with a new, strong, and durable surface.

The first and most critical step is to remove all of the loose and deteriorating material. This is done using mechanical methods, such as a concrete grinder or a scarifier. We must grind down deep enough to reach a solid, stable base of concrete. If we apply a new surface over a weak or crumbling foundation, the repair will fail. After grinding, the surface is thoroughly cleaned to remove all dust and debris, creating a clean slate for the new overlay.

After the preparation is complete, a polymer modified concrete overlay is applied. This overlay is a special high strength material that is designed to bond permanently to the existing concrete. It is spread over the entire surface and finished to create a new, smooth, and durable layer. This new surface is highly resistant to the elements and will not crumble. The result is a concrete slab that looks and performs like new, effectively fixing the crumbling issue and extending the life of the concrete for many years. If the crumbling is extensive and goes deep into the slab, a full replacement may be required.
