grout & sealant
Bentonite sealant in the form of chips (PDSCo Plug), granules (Granular Seal), and powder (PDSCo Grout) are often used to grout/seal well casings or abandon wells. When bentonite is poured or pumped in around the well casing, the ground water in the well hydrates the bentonite chips or granules, allowing them to swell and form an impermeable seal. This seals the well, preventing groundwater contamination from surface runoff.
Bentonite pellets are our specialty. We manufacture clean, dust-free, and easy to handle compressed bentonite pellets, Pel-Plug. For deep setting, we have developed a unique time release biodegradable non-sticking coating that prevents the coated bentonite pellets from swelling upon contact with water for a specific time, which can be applied to both our coated bentonite chips (PDSCo Plug TR30/60) and coated bentonite pellets (Pel-Plug TR30/60).
