Bentonite Soil Sealant Systems make it practical to construct freshwater lagoons and lakes in almost any type of soil and in any configuration. Being a natural material, the bentonite can in no way pollute the stored water and surrounding environment.
GeoSeal or any other bentonite grade specified, with the help of our soil analysis, will form a water tight underseal barrier that will last indefinitely. The unusual flexibility of this material helps it withstand quite strong ground shifts. In many areas where water is both costly and scarce, Bentonite's positive sealing ability is very important. Low in initial cost, this material is usually applied inexpensively, as a mixed blanket between 4 and 6 inches thick.
EFFLUENT STORAGE LAGOONS
GeoSeal can be applied either as a mixed blanket, in the normal manner, or when dry applications is impossible, as a slurry on wet or unstable soils. The only specific requirement for GeoSeal application is complete freshwater hydration before introduction of contaminated wastes. The effluent should be tested to determine ionic salt level. Relatively high ionic salt levels in the effluent can attack and break down the bentonite. A special treatment of the bentonite may be required to protect the bentonite against attack in cases where the effluent has relatively high ionic salt concentrations.
SLURRY TRENCHING AND CUT-OFF WALL CONSTRUCTION
Bentonite is an extremely efficient material for slurry trenching. The bentonite absorbs water and each platelet of clay surrounds itself with a jacket of water thus giving bentonite the ability to develop viscosity. This viscosity permits the stabilization of excavations and the flow of water through trench walls is stopped by Bentonite's soil sealing ability. Fine solids such as sand and silt are kept in suspension for eventual displacement along with the slurry when concrete or other fill is placed in trench.
MUNICIPAL SEWAGE OXIDATION LAGOONS
Bentonite Soil Sealant Systems have become the key ingredient in the building of many municipal waste oxidation lagoons. Hundreds of these lagoons have been operating satisfactorily for years in smaller and medium sized communities. The cost of building a well designed lagoon is usually less than that of an equivalent capacity mechanical plant. Bentonite Soil Sealant Systems are inexpensive and the soil analysis and field advice assures, proper grade selection and correct application for long life.
Unusually flexible to withstand lagoon bottom shifts can mean extremely low maintenance costs. Small leaks are self-mending and larger repairs can be easily made without draining and shutdown.
MUNICIPAL AND INDUSTRIAL LANDFILL LEACHATE SEEPAGE CONTROL
Bentonite Soil Sealant System provides a positive, low cost way to control leachate seepage in municipal and industrial sanitary landfills. GeoSeal will withstand prolonged contact with highly contaminated leachate. Easily applied to the bottom and sides of landfills in a mixed blanket, bentonite provides a low cost, permanent barrier to prevent groundwater contamination. In unusual situations a slurry cut-off wall of bentonite provides a low cost, permanent barrier to prevent groundwater contamination. In unusual situations a slurry cut-off wall of bentonite keyed into the permeable zone, will help control excessive leachate runoff.
Once a landfill is completed and "umbrella" cover of bentonite is placed in a mixed blanket over the entire site. This controls infiltration of water from rain and melting snow thus preventing additional leachate formation.
TANK FARM SEEPAGE PROTECTION FROM OIL AND CHEMICAL SPILLS
Today, spills and leakage in tank farm areas are extremely serious because of the possible seepage of pollutants into groundwater supplies. Bentonite soil sealant can now be used to prevent this type of seepage. Once activated with fresh water, it is totally unaffected by any of the oils and chemicals usually stored in tank farms.
Applied as a mixed blanket inside the dike area. and up the dike slope, the bentonite mixture is then covered with about 4" of soil to provide an insulating, protective work surface. Due to earth shifts that generally occur because of tank loading and unloading, the flexible nature of bentonite is important in providing rupture free, long life protection.
