Bentonite

Bentonite is available as pellets, granules, clay and powder. It is used for sealing, backfilling, grouting or decommissioning boreholes. We stock a range proven to be extremely popular with our drilling and geotechnical engineering clients.

All securely packed in 25kg bags.

Swelltight™ Bentonite Sealing Pellets

SWELLTIGHT® Bentonite Sealing pellets are a quick, clean and easy way to obtain a watertight seal the top of boreholes to stop the ingress of surface water contamination. Extruded Bentonite sealing pellets are prepared from naturally occurring high-purity Montmorillonite, sodium activated Bentonite. Contained swelling volume 40%, free swelling volume >500% (48 hours). Retarded swelling onset 15 minutes. Dimensions 10mm diameter 5-15mm length. All securely packed in 25kg bags

Bentonite Cement / Pellets

Bentonite cement pellets are a quick, clean and easy alternative to using a slurry when grouting or decommissioning boreholes. Typically, they will sink to depth through water and negate the need to use mixers, pumps and tremie pipes.

Bentonite Cement (2:1 ratio) extruded pellet. Montmorillonite Bentonite blended thoroughly with proprietary ordinary Portland cement.

Geoseal™ Grouting Clay

Geoseal™ is a special grouting clay that provides excellent borehole sealing yet is easy to mix and use, giving a conductivity of 0.68 watts/m/^oC when mixed in water or up to 1.86 watts/m/^oC when mixed with sand - see table below.

Geoseal™ has a low swell and slow yield with no flash set, making it ideal for use in Geothermal and subsoil sealing as it has a long working time and can be mixed easily using a wide variety of paddle or cyclone mixers and can be pumped using either a moving diaphragm or piston pump.

Geoseal™ provides excellent bore-hole sealing and fluid loss control, with long-term stability and resistance to drying and because it remains plastic it will deform as the land moves and still maintain an excellent seal on the loop.

Available in bulk, 20kg sacks

SWS Ready Grout

A specially formulated blend of OPC, Bentontite and GGBS specifically designed for ease of mixing to provide excellent sealing and a hard but not brittle final grout what exhibits lower shrinkage and lower heat of reaction than regular bentonite/opc grouts.

KM Ready Grout can be used for general purpose grouting to provide a cut off between different strata or to provide a highly impermeable ground barrier that is slightly plastic and which if required can be cut or drilled out easily.

KM Ready Grout comes ready to mix in water - a high shear mixer or a re-circulating centrifugal pump mixer is advised to achieve full dispersion. It also exhibits slow setting time, good pumpability / workability and low bleed so it is easy to place and will not flash set and requires no special plant.
