Water Well Grouting

The primary purpose of the grout seal in water well construction is to maintain and protect the water quality of an aquifer by preventing contamination from the surface or by preventing commingling of the waters from different aquifers. The materials used must comply with all federal, state and local well construction codes. The grout will have a low permeability to limit contaminant migration and ideally the grouting materials should be easy to install.   

Bentonite and cement are the only accepted materials for annular seals. Bentonite is available in chipped or granular form, processed pellets, or blended with additives to make dispersible grouts. HOLEPLUG® sealing material, BENSEAL® slurry and EZ-SEAL® sealing material are whole bentonite products and AQUAGUARD® material and QUIK-GROUT® material are dispersible grouts. The flow properties and bonding ability of neat cement slurries can be improved by additions of Baroid BARAD-381TM additive. The choice of bentonite or cement should be based on the geologic conditions and subsurface water chemistry at the well site. Choice of casing material also needs to be considered. Bentonite grouts should not be used in areas with chloride content above 1500 mg/l and calcium and magnesium hardness levels above 500 mg/l. In some areas local regulations govern the choice of grouting materials.

Baroid IDP's extensive product line of grouts and additives meets and exceeds all government regulations. The knowledge and expertise of your local Baroid IDP Field Service Representative or the Baroid IDP Technical staff can assist you in the correct product choice for your location and application.
