Hydrotite is a state-of-the-art hydrophilic waterstop with unmatched durability and water sealing capacity.

This expansion creates an effective compression seal within joints of limited movement. Recognized worldwide, Hydrotite has a proven track record as a high quality and cost effective solution to your water containment needs.
