The Best Solution to Anti-chemical- TPV Waterstop
TPV waterstop, also known as TPER waterstop, made of an alloy of rubber and plastic, acts as a fluid-tight diaphragm with excellent mechanical properties and higher chemical resistance than traditional waterstops. Without plasticizer, stabilizer or fillers, the TPV waterstops will not leech out when exposed to chemical fluids as hydrophilic waterstops.

TPV waterstop prefabrications for changing directions
- Ideal for primary and secondary containment structures.
- Sewage treatment facilities.
- Fueling containing areas.
- Mining and refineries industries.
- Structures relating to ozone.
- Manure pits and elevator pits.
- Retaining walls and dams.
- Storage tanks and other water reservoirs.
- Canals and tunnels.
- Roof and floor slabs, parking decks and bridge decks.
Normally, the TPV waterstops are embedded into or installed along extend of joints for preventing water and chemical liquid leaking into the joints, which is the weak point in any concrete structure. As to the changes of directions, pre-fabricated products are needed for easy installation.
To enhance the fixing of waterstops, you could fasten them to surround reinforcing bars with the help of steel wires. For easy installation, our TPV comes with punched flanges, brass eyelets, hog rings or clamps as PVC waterstops according your request.
