"Dmata rebuilt a circa 1929 brick retaining wall at our house that was cracked and in danger to failing in several places. They were able to salvage much of the original brick and mix it in with new brick to create a wall that looks like a perfect match for the original wall. They were also able to fix a number of drainage issues we were having in the front yard at the same time. We have gotten multiple compliments from neighbors on the new wall and it has dramatically improved the drainage in the yard. Dmata also repointed an existing slate patio and re-aligned an existing brick walkway on our property both of which turned out great! They are our first call for any masonry and hardscaping project and we would not hesitate to use them again!"

"They did an excellent job in raising/leveling our garage floor that was sinking. It took longer than expected, but they charge the agreed upon price. They gave us a price per square foot when other contracts could not give us a set price until they discovered how much material would be used. I appreciated the clear pricing and the professionalism of the crew. I highly recommend this company."

Concrete Leveling questions, answered by experts

Yes, you can pour a concrete slab on dirt, but only if you follow specific requirements. A wooden frame is a must, and the soil layer used for the base must be wet enough, thick enough, and compact enough to support the weight of the concrete slab. Consult with a concrete contractor to ensure you have the base you need.

Concrete shrinkage cracks are very common and should be expected. Even professionals end up with shrinkage cracks on newly poured concrete slabs. Remember that these cracks are not harmful to the slab's strength, though some homeowners do prefer to fill in the cracks for aesthetics. When installing concrete, you can avoid ample concrete shrinkage cracks by avoiding hot, sunny, or windy days.

Thicker concrete is less likely to crack due to extreme weather changes. At a minimum, concrete slabs should be at least 4 inches, but if you’re worried about the concrete cracking under the weight of heavy machinery or from the freeze-thaw patterns of your climate, you should use even thicker concrete. A professional concrete company near you will be able to advise on the best thickness for your climate and use case.

Polished concrete floors also have downsides. Some homeowners, for example, might dislike the coldness of the material (though area rugs can help warm up the space). Concrete floors are also hard, which isn’t always ideal for children and pets. What’s more, these floors are susceptible to cracking, and repairs can be costly. Some homeowners might not like that installation isn’t DIY-friendly. 

If you're repairing a sagging or falling fence, a concrete base can strengthen the fence against burrowing animals, erosion, high winds, and more. Having a concrete reinforcement slab installed with a chain link fence can cost $4 to $10 per square foot.
