Description
Hydrotite is a hydroswelling waterstop which seals construction joints effectively. The principal component of Hydrotite is sodium bentonite; a material which swells in the presence of water.
Hydrotite is installed as a rubbery strip in the centre of construction joins. Water which enters the joint will cause Hydrotite to swell. The high swelling pressure of Hydrotite seals any cracks and void effectively.
