Colleen C. had previously sealed her walkway which started to chip away at the joint but shortly after realized the sealant was not adhering to the concrete like she had hoped. After weather, sun and normal wear and tear it was time to find a better solution. We installed a 2 Part system which includes PolyLevel foam underneath her sidewalk to level off and fill any voids below; as well, NexusPro joint sealant was injected into each expansion joint to eliminate water penetrating the soil below. The 2 Part System also includes a transferrable 3 year warranty.
