NO. 330
PVC WATERSTOPS
Prevents passage of water from liquid containing
structures and through foundation walls or tunnels at construction and expansion
joints.
Technical Description
SEALTIGHT PVC Waterstops are extruded from high-quality PVC resins
that are plasticized and stabilized to offer long-life performance, resistance
to abrasion and attack by ozone, oxygen, alkalies and waterborne chemicals.
SEALTIGHT PVC Waterstops are available in a variety of thicknesses, widths and
center bulb sizes. The cross-section configuration features a multi-rib design
for an effective grip and tenacious anchor to the
concrete and a flexible, hollow center bulb to accommodate moderate extension
and transverse movements.
Uses
SEALTIGHT PVC Waterstops are embedded in adjacent pours of concrete
to prevent the passage of water from liquid-containing structures or through
foundation walls and tunnels at construction and expansion joints.
Advantages and Benefits
· Extruded from high-quality virgin PVC resins
· Flexible, lightweight and easy to install
· Resistant to abrasion and attack by ozone, oxygen, alkalies and waterborne
chemicals
Application Tools
Electric Splicer |
Knife |
Application
SEALTIGHT PVC Waterstops should be
securely held in place by splitting the concrete form. They are thermoplastic
and may be field welded using an indirect heating element. When placing the
concrete, thoroughly vibrate it around the waterstop to avoid honeycombs and to
insure complete embedment of the ribbed flange.
