Application |
|
Volclay tablets
are designed for use in the groundwater monitoring industry to form a
chemically resilient, low-permeability, flexible seal. Tablets isolate
screened intervals of monitoring wells and provide an excellent seal for
abandoned boreholes. ¼” tablets are ideal for tight annular spaces, while
3/8” and ½” tablets are useful for larger boreholes.

Characteristics |
-
Chemically
stable. Results from EP Toxicity Metals Analysis are below RCRA limits for
hazardous constituents.
-
Permeability
range of 1 x 10-7 to 1 x 10-9 cm/sec.
-
Will swell to
10 to 15 times their dry volume when hydrated with fresh wate.
-
Self-sealing;
remain flexible when saturated and will rehydrate.

Mixing and Applications |
|
For shallow
applications, add Volclay. Tablets slowly and steadily to prevent blocking
and bridging. For deep applications, tablets may be tremied into place.
Tablets are added and water or air is pumped down the tremie pipe,
delivering the tablets to the desired depth quickly and accurately.
