Uses

A flexible butyl rubber and swellable clay waterproofing compound that swells upon contact with water to form a long-lasting compression seal in non-moving concrete joints. HYPER STOP requires a 2-inch minimum clear

 

coverage from the face of the concrete. HYPER STOP is used primarily for foundation walls slabs, slabs-on-grade, precast wall panels, manholes, pipe connections, box culverts, utility and burial valuts, wet wells, and portable water tanks.

Advantage

 

Easy to install by bonding nailing or casting into joint face. Factory made connectors enable full integration of swellable and exciting waterstop networks.

Swelling properties uneffected by long term wet/dry cycling.

Sustains effective seal in wet conditions.

Description

 

HYPER STOP is high performance hydrophilic bentonite waterstop.

HYPER STOP is made high performance modified bentonite strips. The swelling action is the result between water and hydrophilic groups which are part of the HYPER STOP molecular structure. Expansion of the waterstop creates a positive seal against the face of the concrete joint and prevents the water entry into the structure through the protected joint.
