Enviroplug® no.8, no.16, no.20
ENVIROPLUG® No.8 and No.16 and No.20 are high-swelling Wyoming Bentonite in granular form.
The unique molecular structure allows them to absorb five times their weight of water and swell to a volume of 12 to 16 times their dry bulk, making it an ideal well sealant. Applied dry or in a pumpable slurry, these fine granules expand against casings and formations to create a very low permeability flexible grout seal.
