Description

The VD 320 waterstop is designed and used to seal and prevent water from entering moving joints in monolithic construction. It is used on a variety of objects: from foundations to subway tunnels. It is mounted directly into the body of the reinforcing frame before pouring concrete mortar. The waterstop is widely used in hydraulic structures, such as dams, dams, reservoirs, canals, locks, water intake structures and hydroelectric power plants, as well as for sealing joints in foundations, tunnels, multi-storey car parks and other underground structures.

Internal expansion joint seals of the VD series are used for sealing and waterproofing expansion joints. They are made of EPDM (Ethylene Propylene Diene Monomer) - ethylene-propylene-diene rubber.

Main advantages:

• ensures reliable embedment in concrete structure.

• ribbed surface guarantees tightness, preventing moisture from penetrating.

• deformation zones allow the hydraulic wedge to compensate for movements of reinforced concrete structures without losing tightness.

• used to seal joints between two concrete structures.

• in critical structures, the possibility of additional use of an internal hydraulic key is provided.

• meets high requirements for structural tightness.
