Volclay RX101 Bentonite Waterstop

SKU: WSVRX101 Category:



Waterstop RX is a high-performance bentonite/butyl rubber swellable waterstop for vertical and horizontal cast-in-place and reinforced concrete structural joints. The waterstop is typically placed centrally in the joint and is designed to prevent the migration of water in either direction. The bentonite waterstop will expand up to 15 times its volume in water and will seal cracks using the very pressure of the water itself to fill and block any gaps.
Waterstop RX101 is the most common bentonite waterstop and is 25 x 20mm rectangular shape and available in a 5m roll. Waterstop RX101 requires a minimum concrete cover of 75mm.
Waterstop RX also needs to be secured in place using Cetseal adhesive or concrete nails (sold separately).
