Hydrostop HP 500 PVC external for working seams, blue (price per 1 running meter, sale in multiples of 20 m)

External Waterstops for Construction Joints, HP Series

Used for sealing and waterproofing construction joints during the monolithic construction of tanks, swimming pools, wastewater treatment facilities, dams, underground and buried structures, collectors, and more. Installed directly onto the formwork sheet on the side of the anticipated water pressure.

The waterstop’s shape ensures reliable integration into the concrete structure, while the presence of ribs on the surface prevents moisture from penetrating inside the structure.

Advantages of using waterstops:

• used during pauses in concreting monolithic reinforced concrete structures, and in critical structures can be complemented with internal or external waterstops;

• suitable for structures with high waterproofing requirements;

• withstands high water pressure both inside and outside;

• easy to install;

• does not require modification of the reinforcement cage.
