Description:  Extract from Technical Data Sheets Hydrotite is a hydrophilic waterstop which exhibits excellent durability and water sealing capacity.  It expands as it absorbs water and fills up concrete joint gaps conforming to the gap variation, ensuring excellent sealing. It consists of a unique combination of expanding hydrophilic materials and non-expanding chloroprene rubber co-extruded together to form a single strip.  The expanding section is blue with the non-expanding section being black.  The co-extruded design means that the expansion is directed across the joint for maximum sealing performance.

Hydrotite, as with any hydrophilic waterstop will return to its original size if there is no more water or moisture present.  Hydrotite will then re-expand when water or moisture is again introduced to the joint.
