Sodium Bentonite Systems

A range of bentonite-based waterproofing products, comprising highly effective waterproofing geo-composite membranes and compounds, designed to prevent the passage of water and water vapour.

These systems contain high swelling sodium bentonite, and are generally pre-applied prior to placement of insitu concrete. The sodium bentonite systems then form a strong mechanical bond to concrete, thus forming a dense, monolithic, impervious waterproof layer.
