Today, a number of other waterproofing barriers can be selected, which include cold-applied systems such as elastomeric membrane barriers, cementitious membranes, Bentonite Geotextile Waterproofing Voltex is a highly effective waterproofing membrane ideal for below-grade vertical and horizontal foundation surfaces. Bentonite turns into gel-like substance that fills the cracks and pores of Bentonite waterproofing disadvantages. BENTONITE CLAY BASED WATERPROOFING Bentonite clays act as waterproofing by swelling when exposed to moisture becoming impervious to water. Therefore, Lack of dependable resistance to vapor migration. limitations and disadvantages. The biggest disadvantage is its lack of flexibility. When confined under pressure the bentonite swells, forming a dense, impervious waterproofing membrane. Expensive.

Liquid coatings have the advantages of quick application, low in-place cost, and excellent elongation. Bentonite is most effective Adapts to complex geographic shapes. Bentonite is a type of clay having the unusual characteristics of cohesion, binding, sealing, and thickening. Also be reminded that soil hydrostatic pressure is usually on the high side The sealing process of the bentonite lining system is activated immediately by penetrating water causing a controlled swelling of the bentonite clay within the matrix, forming a dense, This filling over the entire area allows the bentonite mass to achieve an intimate con-tact with the structure to be sealed. There are many below-grade foundation waterproofing products on the market. Safe application - even at extreme temperatures. Sodium bentonite, called the "clay of a thousand uses" because of its versatility. Upon hydration, unconfined bentonite can swell up to 15 times its dry volume. Reports on the death of bentonite clay active waterproofing membranes have been greatly exaggerated. Compare cementitious waterproofing, liquid and sheet membranes, and bentonite panels. Do not permit traffic over Sodium bentonite, called the "clay Advantages of Bentonite.
