The sodium bentonite is very important in the building industry for its ability to absorb water expanding up to 12-16 times compared to its dry volume, which makes it ideal for producing waterstop, sheets, panels, rolls and shaped self-sealants, for waterproofing of masonry or concrete walls against ground.

The CLAYSEAL waterstops, for alkaline water CLAYSEAL 25.20 and for brackish and/or leachate water CLAYSEAL 25.20 SW, are a splendid example of products that have taken advantage of the peculiar hydro-expansive capacity of sodium bentonite.

 

 

CLAYSEAL 25.20

Preformed hydro-expansive sealing waterstop joint, for hermetic sealed construction joints in structures, walls and foundations, made with a mixture of sodium bentonite, expanding rubber and special aggregating polymers ("hydrocarbon" ). CLAYSEAL 25.20 has a rectangular cross-section of 25x20 mm, packaged in rolls of 5 m each.

BENTONET

Trapezoid preshaped steel square mesh cage open only on one side, to be used to encourage correct positioning of the CLAYSEAL 25.20 sodium bentonite waterstops, and to prevent the displacement from the seat provided, especially in complex situations or on surfaces which are not perfectly prepared. Once the joint is inserted, BENTONET will have to be fixed to the concrete support using steel nails and washers every 20-25 cm.

PROSEAL FIX

Permanently elastic, modified silane-based polymeric adhesive for sealing gaskets, joints and curbs, of both bentonitic (e.g. CLAYSEAL 25.20, CLAYSEAL 25.20 SW) and hydro-expansive rubber (e.g. SEALGUM 20.05), for waterproofing cast elements. The adhesive is a substitute for the more traditional nailing of sealants.
