Abstract:
Integral crystalline waterproofing (ICW) is absorbed by capillary action and diffusion into the concrete where crystals grow to fill capillaries and voids in the concrete matrix. This continues as long as moisture remains present. If the concrete dries, the chemicals sit dormant until another dose of water causes the chemical reaction to begin again, and more crystals grow to seal any new cracks. The benefits of ICW are demonstrated in this case study of an elevated swimming pool that developed severe shrinkage cracks and leaking soon after construction was completed.
