Waterstop-RX is an active bentonite/butyl-rubber based waterstop designed to stop water infiltration through cast-in-place concrete construction joints by expanding upon contact with water to form a positive seal against the concrete.

The key to the effectiveness of Waterstop-RX is it’s 75% sodium bentonite content which provides superior expansion to seal cracks and fill small voids. Waterstop-RX is a reliable and cost-effective solution to preventing water infiltration through concrete joints.

Waterstop-RX offers a low cost opportunity to enhance the performance of a sound external waterproofing system, by sealing the areas of highest probability of water infiltration through the concrete, and should therefore be implemented as part of the waterproofing design.

Waterstop-RX can also be refereed to as a swellable water bar when being used in projects involving new to old slabs joins.

 

Performance

APPLICATIONS: Applications include both vertical and horizontal non-moving concrete construction joints, new to existing concrete construction, irregular surfaces, and around through-wall penetrations, such as plumbing and utility pipes. Additionally Waterstop-RX can seal around concrete pilings and steel H-piles passing through the slab. Waterstop-RX works in both continuous hydro-static and intermittent hydro-static conditions

B2 DURABILITY: Performance B2.3.1 (a) not less than 50 years.
E2 EXTERNAL MOISTURE: Performance E2.3.3.
F2 HAZARDOUS BUILDING MATERIALS: Performance F2.3.1. The Volclay Waterproofing System meets this requirement and will not present a health hazard to people.
