It is a specially formulated polyurethane- based material with a hydrophilic agent dispersed evenly throughout the paste. Akwaswell is installed with a standard caulk gun and self adheres to dry concrete surfaces; no mechanical fastening or adhesives required. The key to Akwaswell’s effectiveness is its 500% swelling capacity when wetted and its plasticity to contour the surrounding surface. This swelling action creates a positive seal against the concrete in construction joints and stops the flow of water through the joint. Akwaswell has been successfully tested to 115 feet of hydrostatic pressure when properly installed in concrete joints. Application : Ideal for rough concrete surfaces and irregular penetration surfaces. Other applications include horizontal and vertical poured-in-place concrete joints, new to existing concrete pours, around penetrations, and concrete repair joints. Not an expansion joint material. Minimum concrete coverage is 2". Allow to cure 24–36 hours before concrete placement. Coverage : One 10.5 fl. oz. cartridge covers approximately 20 LF.
