Waterproofing

Our group of companies has vast experience with all major types of waterproofing systems, both above and below grade. These materials and systems may include sheet waterproofing, blindside and underslab waterproofing, bentonite, fluid-applied liquid membranes, hot-applied rubberized asphalt, crystalline materials, and drainage materials. The type of system utilized will be determined by the design professional and the intended location (horizontal, vertical, above or below grade). Our staff has the training and expertise to install these systems properly.
