It expands immediately upon first contact with water and fills the void and cracking, forming filler throughout the leaking path that seals against the concrete walls. At the moment of hydration, the seal expands up to three times its size in an open area but is limited to controlled expansion within the concrete joints. The effectiveness of this durable waterstops is achieved by high content of sodium bentonite mixed with butyl rubber, which provides outstanding swelling performance. It is designed to replace commonly used plastic or rubber waterstops by eliminating the need for additional metal segments and frame-work.Easy Installation Saves You MoneyLaney Selection Expandable waterstop strip is also easy on your budget, saving you money in time and installation. Designed for greater performance predictability, it replaces traditional PVC/Rubber dumbbell waterstops and eliminates the need for special pieces, split-forming, and seams. It is manufactured in lightweight, flexible coils, making installation so quick and easy—simply apply Laney Selection Waterstop to a prepared surface and press into place—that a single worker can install it without extensive training.
