Sub-Slab Drainage and Waterproofing
PL:BECS has extensive acquaintance with sub-slab drainage and waterproofing methods. Product familiarity includes various bentonite-clay, composite sheet membrane and bentonite-clay systems, integrated bentonite-polymer materials, concrete-activated sheet membranes, drainage mats, geotextile fabrics, bentonite and swelling-sealant joint water-stops, drainage piping, crack-resistant low-shrinkage concrete slab mixes, epoxy and polyurethane injection grouts, related mastics, sealants, and other materials. Experience includes the design, construction oversight, as well as hands-on installation of many such systems, including several which were immersed several feet underwater, as well as the preparation of a technical guide on the subject, General Recommendations for Floor Slab Assemblies. Extensive design and field experience is supplemented by appreciable training and familiarity with geologic factors contributing to high-risk floor slab exposures.
