Description EnviroPlug® Coated and Non-Coated Tablets are used
in piezometer holes, monitor wells, and other sealing and
plugging applications. Non-coated tablets are available in
1/2”, 3/8”, and 1/4” sizes, while coated tablets are
available in 1/4” and 3/8” sizes. EnviroPlug® Tablets

Function
Coated EnviroPlug® Tablets make a high density, low permeability seal between
sand packs and high solids bentonite grouts, and isolate screen sections in multi-
completion wells. Hydration of Coated EnviroPlug® Tablets is slowed due to their
coating, and can therefore be placed through a tremie line. This results in deeper,
more predictable tablet placement. Their coated exterior also prevents a ‘sticky rind’
from forming once water contacts the bentonite.
Mixing
EnviroPlug® Tablets should be poured directly into the hole or placed by the tremie
method. As with gravel packing, the desired result is a ‘bentonite pack’. Therefore,
take care in placing the tablets to prevent bridging. The tablet seal or plug should be
placed against an impervious formation, such as clay. EnviroPlug® Tablets should
be allowed to hydrate 1-2 hours before any grout is installed.
A wide variety of sealing products and application methods exist. Please consult
local regulations, a groundwater professional or a product representative prior to
commencing any sealing or abandonment procedure.
