Control Joint & Crack Sealing
Seal expansion joints to stop subgrade water erosion under driveways and patios.
Control joints are cut into concrete to direct natural cracking. However, open joints allow rain and melted snow to rush underneath the slab. Over time, this washes away supporting dirt, causing driveways to sink and crack unevenly.
We clean out joints and apply self-leveling polyurethane or silicone sealant that remains flexible through hot summers and freezing winters.
