Waterproofing Solutions

Water is capable of causing huge damage to the structures that we build if it is not kept under control. Bondlast understand the many problems associated with keeping water where is should be. We offer water tight solutions for all the important areas in any home and business (all based on water based liquid polymer technology). Whether it be for ground water control (positive hydrostatic pressure), for waterproofing decks, parapets, swimming pools, bathrooms, showers, kitchens, or even decorative finishing of concrete slabs (inside or outside); Bondlast can provide a specification to keep water in or out.
