Waterstop Bentonite

Description

Waterstop Bentonite

Bentonite Waterstop is based on active sodium bentonite in the matrix of butyl rubber with high elasticity and is specially designed to prevent the leakage of executive seams and water infiltration and the interruptions of concreting. When bentonite waterstop comes in contact with water, it expands and prevents water from passing through the concrete joints.

properties and effects

• The ability to fill concrete seams and holes
• Permanent and flawless performance
• High malleability and relatively free

Application

• Sealing of executive seams of horizontal and vertical surfaces
• Sealing uneven surfaces or possible cold joints
• Sealing of shear concrete sections and bearing walls
