ACCU-VIS® & BELLE CRUMBLES

ACCU-VIS & BELLE CRUMBLES blends a granular bentonite with a consistently controlling liquid polymer to form a slurry that provides an economical way to seal and grout boreholes, well casings, and earthen structures. Once set, the slurry forms a complete grout seal with low permeability.

C/S GRANULAR & CETCO® CRUMBLES

C/S GRANULAR and CETCO CRUMBLES are granular bentonite products composed of polymer-free, dried bentonite in various mesh sizes. CETCO CRUMBLES are coarser in size than C/S GRANULAR. Both are certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals - Health Effects.

CETCO® COARSE CHIPS

CETCO COARSE CHIPS are natural sodium bentonite screened to 3/8 inch to 3/4 inch in size. PUREGOLD MEDIUM CHIPS are natural sodium bentonite screened to 1/4 inch to 3/8 inch in size. Both are certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals - Health Effects.

CETCO® COATED TABLETS

CETCO COATED TABLETS are coated using an aqueous carrier to apply the coating. These untreated organic tablets are compressed into 1/4” (0.64 cm) and 3/8” (0.95 cm) sizes. CETCO COATED TABLETS are certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals - Health Effects.

CETCO® GRANULAR GROUT

CETCO GRANULAR GROUT mixes into a smooth bentonite grout that has no lumps and pumps easily. CETCO GRANULAR GROUT is certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals - Health Effects.

CETCO® GROUT

CETCO GROUT is a 20% solids, polymer-free, single-component, easy-to-use sodium bentonite grout available in powdered form. CETCO GROUT allows placement in a low viscosity state. CETCO GROUT is certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals - Health Effects.

CETCO® MX-80

CETCO MX-80 is a granular bentonite product composed of dried bentonite clay with a typical size range between 30 and 100 mesh.

CETCO® TABLETS

CETCO TABLETS are organic free, high-swelling pure sodium bentonite. CETCO TABLETS are compressed into 1/4 (0.63 cm), 3/8” (0.95 cm), and 1/2” (1.27 cm) diameters. CETCO TABLETS are certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals - Health Effects.

GEOTHERMAL GROUT

GEOTHERMAL GROUT is a specially blended high solids bentonite that can be mixed with sand in a two-part thermally conductive grouting material to improve the performance of ground source heat loop applications. GEOTHERMAL GROUT is an easy pumping grout that has been carefully developed to efficiently suspend solids (silica sand) for enhanced thermal conductivity. GEOTHERMAL GROUT can be mixed to meet a range of thermal conductivity (TC) from 0.40 to 1.00 Btu/hr/ft/F (0.68 to 1.69 W/mK). GEOTHERMAL GROUT is certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals - Health Effects.

GROUNDING GROUT

GROUNDING GROUT is a high-solids, single-component bentonite grout. GROUNDING GROUT is specially formulated to provide a conductive seal around grounding rods. When used to seal drilled boreholes in which vertical grounding rods are placed, GROUNDING GROUT increases the grounding system’s conductivity by lowering the resistivity from 300 ohms/meter with normal soil to 0.76 ohms/meter. GROUNDING GROUT adheres to the entire surface of the grounding rod, providing the smallest surface area and, consequently, offering the greatest effective resistance area. This helps to stabilize the ground resistance despite seasonal changes in temperature and soil moisture content.

HIGH TC GEOTHERMAL GROUT

HIGH TC GEOTHERMAL GROUT is a specially blended high solids bentonite that can be mixed with sand in a two-part, thermally conductive grouting material to improve the performance of ground source heat loop applications. HIGH TC GEOTHERMAL GROUT is an easy pumping grout that has been carefully developed to efficiently suspend solids (silica sand) for enhanced thermal conductivity. HIGH TC GEOTHERMAL GROUT can be mixed to meet a range of thermal conductivity (TC) from 0.40 to 1.21 Btu/h/ft/F (0.68 – 2.05 W/mK). HIGH TC GEOTHERMAL GROUT is certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals - Health Effects.

PUREGOLD® GROUT

PUREGOLD GROUT is an easy mixing, organic-free, high-solids bentonite grout engineered to form a contaminant resistant seal without affecting groundwater chemistry. PUREGOLD GROUT is certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals - Health Effects.

PUREGOLD® MEDIUM CHIPS

CETCO COARSE CHIPS are natural sodium bentonite screened to 3/8 inch to 3/4 inch in size. PUREGOLD MEDIUM CHIPS are natural sodium bentonite screened to 1/4 inch to 3/8 inch in size. Both are certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals - Health Effects.
