CETCO'S BENTONITE TABLETS
Cetco's regular bentonite tablets are a pre - formed compressed tablet made from high
swelling sodium bentonite - stocked here in Denver in the 3/8" size. They will form a
flexible, permanent, non -toxic seal in monitoring well applications where water flow
and hydrostatic pressures are involved. Cetco's tablets will swell 10 to 15 times their
dry volume when hydrated with fresh water and will not shrink or crack over time. The
smaller your annular space ( ie the distance from the outside of the casing to the
borehole wall ) the smaller the diameter of tablets that should be used. Tablets will
provide you with an in place expansive bentonite seal for your most sensitive
monitoring well applications. Tablets can be placed in either a wet or dry borehole
with the same ease as pea gravel. Cetco's tablets are packaged in 5 Gallon Pails (50
lbs per Pail) and are palletized & shrink wrapped 36 Pails to a Full Pallet.
Purity - - -- Montmorillonite content of about 90% minimum
contains small portions of Feldspar, Biolite, Senenite, ect.
Specific Gravity - - -- 2.3 to 2.5
P11 Value - - -- 8.5 to 10.5
Dry Bulk Density - - -- 82 lbs per cubic foot
3/8" CETCO Coated Bentonite Tablets
Now you can pour pellets easily in the bore holes with standing water without the
problems such as bridging from premature swelling. Cetco coated tablets combine the
best of a high yielding virgin western bentonite ( for expansion of up to 12 times dry
volume size ) and the coating for a delayed hydration. This allows Cetco tablets to be
efficiently poured or pumped in place down to a depth of up to 150' through standing
water. This method reduces waste, time, and handling costs associated with the semi
liquid methods presently used. Celco coated tablets are stocked in 3/8" size.
