Pvc waterstop is designed to provided an overall sealing system for the movable joints and construction joints in cast-in-place concrete. such joints usually exist in the following types of buildings.

Water storage building:

Reservoirs, water towers and sewage towers

Dams, culverts, canals and spillways

The swimming pool

The berm area around the storage tank

Waterproof building:

Basement and underground parking

Tunnels and underpasses

Abutment and retaining walls

Roof deck and podium area

Functional principle of pvc waterstop:

1. Dumbbell shaped waterstop is poured through concrete and embedded in the edge of adjacent concrete, and the concrete slab acts as a baffle. When the joint is opened due to dry shrinkage or other displacement, the edge bulge on the section of the waterstop will play an anchoring role. Therefore, the transverse tension of the waterstop will produce a sealing effect on the inner surface of the edge bulge.

2. After the section of the waterstop becomes complex, its surface area will be greatly increased, which will have a greater organizational effect on the water leakage of the waterstop section, and the complex path formed on the section will make it difficult for water to pass through.
