Product Description

 

HYDRO-EXPANSIVE BENTONITE JOINT

Product Description

The Willmore bentonite joint is a joint based on sodium bentonite and organic binder, which is used for sealing construction joints of underground structures, and sealing non-mobile joints from any possible ingress of water . When in contact with water, the profile gradually increases in volume, ensuring waterproofing, once it is confined between concrete and concrete.

The joint expands by 200-300% in volume and resists a water pressure of 5 bar (50 m).

A typical application is in the waterproofing of construction and connection joints, on concrete structures located at water level. Integrated into concrete construction joints, the curb expands in contact with water sealing the structure.

The hydro-expansive waterstop bentonite joint provides a permanent sealing, guarantees total safety, excluding potential defects that may derive from conventional construction, as well as all losses deriving from water infiltration.

The Willmore hydro-expansive waterstop joint is available in size 20x25 ,18x7 ,10x5,20x10, also we accept customized.
