Part # RX101T
Waterstop-Rx Expanding Concrete Joint Water stop. Waterstop-RX 101T is produced in a trapezoidal shape measuring 1-1/4" (31 x 12 mm) with a reinforcing plastic scrim embedded in the top surface for high tensile strength. The patented trapezoidal shape distributes the expansive force over a greater area and allows the concrete to flow more readily over the product during placement. RX-101T is designed for concrete 8" (200 mm) thick or greater with two rows of reinforcing steel.
Waterstop-RX is a reliable, cost-effective means to stop water infiltration through concrete cold joints. It can also be used around pipe and structural penetrations.
Waterstop-RX is a sodium bentonite 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 Waterstop-RX’s effectiveness is its high sodium
bentonite content which provides superior expansion to seal and fill voids and cracks in the
concrete. Waterstop-RX is an 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. Waterstop-RX has been successfully tested by independent testing firms to over 200 feet (60 meters) of hydrostatic water pressure, under both continuous immersion and wet/dry cycling.
Though Waterstop-RX possesses good resistance to many chemicals, the waterstop is not
intended to be used as the primary joint sealant for chemical containment vessels. Consult
manufacturer for guidance regarding chemical compatibility for secondary chemical containment
applications. Additionally, Waterstop-RX is not an expansion joint sealant. Expansion joints require an expansion joint product provided by others.
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 hydrostatic and
intermittent hydrostatic conditions.
Waterstop-RX products are designed for reinforced structural concrete with a minimum
of 3,000 psi compressive strength.
