- Product Information
More recently, a new trend has begun in hydraulic barrier design, based in the production of a combination of bentonite and geosynthetics (geomembranes and geotextiles). It consists of a compacted clay barrier between a layer of geotextile and another layer of geomembrane (manufactured plastics, as high-density polyethylene or polypropylene, among others).
The distinctive features that make bentonite a good sealer are mainly its high specific surface, great swelling capacity, good plasticity and lubricity, high impermeability and low compressibility. Sodic bentonites are most widely used for this purpose because of their high swelling capacity.
Sodium bentonites are also used as sealants and as liners in the following situations:
* As a liner to prevent fresh water flow from pools and ponds, golf courses, channels, etc.
* As a li er to prevent waste water flow from industrial waste sites.
* In contaminated soils: sheeting and verical barriers.
* As a sealant in contaminated underground water wells.
* In radioactive waste sites: underground repositories, crack sealing in granites, etc.
Applications & Uses
- Applications
- Application Rate
The proportion of bentonite to use varies between 3% and 10%, depending on the type of soil and the pessure or erosion it is subjected to.
