Crocodile Expanding Waterstop is made from Bentonite and Butyl Rubber which provides superior expansion to seal cracks and fill small voids. It is a flexible strip concrete construction joint waterstop that provides a positive seal by expanding upon contact with water. Crocodile Expanding Waterstop is an active waterstop that functionally replaces conventional passive PVC dumbbell waterstops. It is designed for both continuous and intermittent hydrostatic conditions and hydrostatic head resistance 120 PSI (8 bar).
Application
- The substrate must be sound, clean dry and free from all surface contaminants.
- Remove protective backing from the adhesive side , and press a continuous roll of Crocodile Expanding Waterstop firmly onto the surface.
- Ends can be either butt-joined or kneaded together to form a continuous, uninterrupted seal.
- On vertical installation, it is recommended to use adhesive or nails to ensure firm fixing of waterstop during concrete placement. Besides use of adhesive or nails, the use of nails at approximate 30 cm spacing is allowed for waterstop installation.
- Do not allow waterstop to be exposed to rain or standing water prior to pouring of concrete.
The recommended concrete covering depends on the size of waterstop:
- Concrete covering > 20 cm, waterstop size 25 mm x 20 mm
- Concrete covering < 20 cm, waterstop size 20 mm x 15 mm
- Pipe application, waterstop size 20 mm x 10 mm
