Cracked concrete happens when part of a concrete slab breaks and sinks into underlying soil that has compressed or washed away. These cracks aren’t just unsightly; they offer moisture a way to seep beneath the slab. This can cause the underlying soil to soften or even wash away completely. That, in turn, can cause the slab to crack further as sinks into the void left by the washed-away soil.
To prevent moisture from seeping into the soil beneath, those cracks need to be sealed, as do the control joints that were cut between the slabs when they were first poured. While you could seal them with urethane caulk found at your local big-box DIY store, that is a solution that is prone to cracking, bubbling and drying out over time. Which means you’ll likely be sealing them again… and sooner than you thought.

The PolyRenewal™ Solution
Thankfully, fixing cracks in concrete has never been easier, thanks to a breakthrough in technology only available from Foundation Recovery Systems.
PolyRenewal™ 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, PolyRenewal™ 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 PolyRenewal™ 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 PolyRenewal™ 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.
