HDBR Waterstop

HDBR Waterbar is a green Elastomeric Hydrophilic strip made of natural sodium bentonite clay and synthetic rubber designed for the integral sealing of construction joints in cast-in place concrete. HDBR Waterbar expands up to 400% of its original dry volume on contact with water to form a positive seal.

HDBR Waterbar is also suitable for use in potable water situations.

ADVANTAGES

HDBR Waterbar is a permanently active ecological and user friendly system simple and quick to install.

The composition of HDBR Waterbar prevents premature swelling.

HDBR Waterbar has a proven track record in water treatment plants, water purification plants, underground parking lots, water reservoirs, swimming pools, water tanks, metro works and other concrete structures subject to high water pressure.

HDBR Waterbar can resist hydrostatic pressures of up to 40 metres of water column = 4 bar.

The durability and performance of the HDBR Waterbar will exceed the design life of the structure.

HDBR Waterbar will not dissolve in water and is non-polluting.

APPLICATIONS

Applications include both vertical and horizontal non-moving concrete construction joints, new to existing concrete construction, irregular surfaces and around through-wall penetrations; such as plumbing and utility pipes.

HDBR Waterbar works in both continuous hydrostatic and intermittent hydrostatic conditions.

HDBR Waterbar is designed for use in reinforced structural concrete, utilising two rows of reinforcing steel, with a minimum thickness of 200mm, providing the HDBR Waterbar with no less than 70mm concrete cover to all sides.

HDBR WATERSTOP expands upon contact with water to form a positive seal even in saline conditions.
