PVC Waterstop TDS
Technical data sheet for Petroseal PVC waterstops — centre-bulb, dumbbell and kicker profiles in 150, 200 and 250 mm widths for watertight concrete joints.
Petroseal PVC waterstops are extruded flexible PVC profiles cast into concrete at construction and movement joints, forming a continuous barrier against water passing through the joint in basements, water tanks, tunnels and other water-retaining structures.
Fix at the flanges only, never through the bulb or web, and join by heat welding — lapped or taped joints are not watertight. Use factory-made intersections at tees and corners.
