After lifting and leveling your concrete stairs with PolyLevel, our crews fill and seal any cracks or joints. This prevents water infiltration through cracks and joints, which in turn helps prevent the soil below your concrete stairs from softening and eroding over
time. We use a high quality, silicone-based sealant called NexusPro. It’s specially engineered to stand up to harsh weather conditions, and unlike traditional urethane sealants, it is UV-resistant to prevent drying, cracking, bubbling or yellowing.
