Waterstop-RX
®
is a concrete construction joint waterstop that
provides a permanent seal by expanding upon contact with water.
Waterstop-RX
®
is an active sodium bentonite based waterstop
that is designed to replace conventional passive PVC dumbbell
waterstops, thus eliminating the requirement of split-forming and
product seam welding.
Waterstop-RX
®
is manufactured in lightweight, flexible coils that can
be installed in both hot and cold weather. The product is adhered
to concrete, steel, and PVC (pipes) with
CETSEAL
sealant/adhseive;
at or exceeding the required minimum distance from the exterior
concrete surface.
The key to Waterstop-RX
®
is sodium bentonite. Sodium bentonite
swells when in contact with water, forming an impermeable barrier.
This swelling property allows Waterstop-RX
®
to form a permanent
pressure seal within the concrete joint, thus eliminating water
migration over or along the waterstop.In addition to forming a
positive pressure seal, the products expansion properties allow it to
seal small cracks and void areas.
Waterstop-RX
®
is designed for structural concrete with a minimum
of 3,000 psi.
RX 101
and
101T
, require a minimum 3" of concrete
coverage.
RX 102
requires a minimum concrete coverage of 2".
RX 101 and 101T are designed for vertical and horizontal reinforced
concrete 8" thick or greater, with two rows of reinforcing steel.
RX 101 has more water resistance and will react slower in water or
wet conditions before concrete is placed. RX 101T (trapezoidal)
is recommended for shotcrete or gunite concrete construction,
extreme hot weather and difficult applications. RX 102 is designed
for vertical reinforced concrete 5" thick or greater; and horizontal
reinforced concrete 4" thick or greater. RX 102 is designed primarily
for concrete with one row of reinforcement.
CETSEAL
is a multi-purpose, low VOC, 100% solids, single component
polyether moisture cure adhesive used to secure Waterstop-RX
®
into position. Apply a continuous bead of CETSEAL to substrate then
install Waterstop-RX
®
before CETSEAL skins over and cures within 30
minutes. Adhesive yield will vary with use, substrate and application.
