Working as an active barrier for structures under either continuous or intermittent hydrostatic pressure, WATERSTOP-RX® substantially reduces the possibility for leaks—its active volcanic bentonite component absorbs up to 15x its volume in water, expanding to seal cracks using the very pressure of the water itself to fill and block any gaps.

WATERSTOP-RX® 101T is produced in a trapezoidal shape measuring 31 x 12 mm (1-1/4” x 1/2”) with a reinforcing plastic scrim embedded in the top surface for high tensile strength.

RX 101 and RX 101T are designed for vertical and horizontal reinforced concrete 200mm (8”) thick or greater, with two rows of reinforcing steel (see Figure 2.1). RX 101T (trapezoidal) is recommended for shotcrete or gunite concrete construction, extreme hot …

Cetco Waterstop-RX is an expanding strip waterstop designed to stop water ingress through cast-in-place concrete construction joints. Upon contact with water, it expands to form a positive seal against the concrete.

Waterstop-RX is designed for both continuous and intermittent hydrostatic conditions and has been successfully tested to resist 231 ft (70 m) of hydrostatic pressure. The key to the effectiveness of Waterstop-RX is its high sodium bentonite content which provides superior expansion to seal cracks and fill small voids.

Active bentonite/butyl-rubber based waterstop that is designed to replace passive PVC/Rubber dumbbell waterstops, thereby eliminating the requirement of special pieces, split-forming and seam welding. A flexible strip concrete construction joint sealant that provides a permanent watertight seal by expanding upon contact with water.

WATERSTOP-RX is a hydrophilic strip 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 WATERSTOP-RX’s effectiveness is its superior expansion to seal and fill voids and cracks in the concrete.

Waterstop-RX 101T - Trapezoidal shape measuring 32 x 12.7 mm, the RX-101T distributes the expansion pressures over a greater area and the reinforcing scrim provides additional product stability when concrete is placed. Best used for shotcrete applications requiring 75 mm of concrete coverage.
