CETCO GRANULAR GROUT mixes into a smooth bentonite grout that has no lumps and pumps easily. CETCO GRANULAR GROUT is dust free, offers reduced friction going down the tremie pipe, and has a firm set-up with little settling. CETCO GRANULAR GROUT is certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals – Health Effects.
CETCO GRANULAR GROUT is designed for grouting waterwells and monitoring wells, decommissioning abandoned wells and boreholes, and sealing closed-loop geothermal heat pump systems. It forms a low-permeability, flexible seal.
• Improved set-up time allows mixing flexibility and reduces settling
• Physically stable; will not flow through highly permeable soil
• Smooth consistency for improved pumping and handling
MIXING & APPLICATION:
WATERWELL – 20% SOLIDS
Add one 50 lb (22.7 kg) bag of CETCO GRANULAR GROUT to 24 gallons (91 liters) of freshwater to produce 3.5 ft3 (0.11 m3) of grout. Once mixed to proper consistency, grout should be pumped through a tremie pipe with a positive displacement pump from the bottom of the well up to the surface. Pumping should continue until grout at the surface reaches the initial mud weight of 9.4 lbs/gal (0.63 kg/m3).
GEOTHERMAL – 40% SOLIDS
Place freshwater in a paddle-mixing tank of a commercial grout mixer. Start the paddles and add one 50 lb (22.7 kg) bag of CETCO GRANULAR GROUT to the water. Mix for about 1 minute. Add silica sand at a steady rate (1-2 minutes), and continue mixing for about 2 minutes to obtain a consistent mixture. Pump with a positive displacement pump (piston pump recommended) through a 1 to 1 1/4 inch (2.54 cm to 3.18 cm)
inside diameter (I.D.) tremie pipe at a rate of 5-15 gallons (19-57 liters) per minute. Yields 4.52 ft3 (0.13 m3).
