Concrete Cracks in Garage
The causes of concrete settlement and sinking are the same whether it's a driveway, walkway, patio, garage floor, or pool deck. As soil underneath a concrete slab shrinks, settles or washes away, this leaves empty space, or voids, beneath the slab. With the soil no longer supporting the slab, the concrete will sink, creating an uneven surface.
More Cracking
Concrete slabs are often poured on wet, weak, or poorly compacted soil. Over time, this will lead to settlement of the slab, causing uneven floors or cracking. Inside your home, your floor will pull away from walls and doorways, creating gaps at the seams.
Concrete Repair Solutions
Frontier Foundation & Crawl Space Repair provides expert concrete repair solutions using the PolyLevel® system. PolyLevel® is an expanding polyurethane foam that is injected beneath the concrete to fill the gaps caused by soil erosion and raise and stabilize the concrete surface.
Concrete Lifting
PolyLevel® is an alternative solution to traditional mud jacking that lifts concrete slabs to a level position and provides long lasting stabilization. 4
Strong but light
PolyLevel® weighs only about 4lbs. per cubic ft., compared to 120lbs. per cubic ft. for standard fill material. PolyLevel®'s light weight makes it useful where denser fill material might impose an undesirable load on weak soils. Despite its light weight, PolyLevel® can support substantial loads; it typically provides greater lifting power than mudjacking.
NexusPro
NexusPro sealant is a long-lasting solution for repairing cracks in any concrete slab.
Cracks Sealed
NexusPro is a silicone-based sealant for joints and cracks specially formulated to provide long-lasting flexibility and to stand up to harsh weather conditions. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble or dry out. That means a single application can seal the joints and cracks in your concrete driveway, patio, pool deck or sidewalk for years to come, protecting it from damage caused by soil compaction and washout.
Quick to Install, Quick to Cure
The NexusPro solution is installed by a highly trained crew that specializes in concrete repair and protection. First, the cracks are drilled, smoothed and prepared with non-absorbent backer rod filler. Then, the NexusPro sealant is inserted in the prepared crack or control joint. Finally, the cracks are detailed with a thin layer of native sand, giving the concrete a uniform, finished appearance. And, of course, sealed concrete cracks mean no unsightly weeds growing through.

Thankfully, fixing cracks in concrete has never been easier, thanks to a breakthrough in technology only available from Frontier Foundation & Crawl Space Repair and other concrete repair contractors in the Foundation Supportworks network.
