Hydrophilic Bentonite Rubber Waterstop/Swellable waterstop strip
PENNBAND Swellable waterstop is a putty type self-adhesive swellable clay waterproofing compound that is glued or nailed in strips into construction joints. Known as a hydrophilic waterstop system, bentonite expands up to sixteen times its dry volume when it comes into contact with water, forming a compression seal in concrete joints. Bentonite's ability to swell enables it to fill small cracks and voids in concrete, preventing the ingress of water around joints. And since clay is a natural material, bentonite is a popular waterstop choice for potable water applications.
Advantages
1. High tensile strength, high tear resistance.

9, anti aging, no shrinkage, no hardening, no oxidation.
10. Withstand severe temperatures from - 30 ° f to 200 ° F.
11. Non toxic.
12. No special treatment is required.
Where to use it?
PENNBAND P swellable waterstop can be widely used in swimming pools, waste water / sewer solution projects, underground railway, tunnels, culverts, buildings etc, in the construction joints, expansion joints and cracks of concrete constructions. It is designed for water stop / waterproof of concrete joints.
Expansion joints are components designed to safely absorb the thermal expansion and contraction of various building materials, absorb vibration, or allow movement due to land subsidence or earthquake.
They usually appear between sidewalks, bridges, railway tracks, piping systems and other parts of structures.
