1 <br />Groundwater Division <br />1 <br />1 <br />Volclay®Grout <br />~~ High Solids Bentonite Grout <br />'_ (New 1-Step Mix) <br />DeSCriptlon: Volclay®Grout is a 20% solids, polymer free, single component, <br />bentonite grout. <br /> <br />' Recommended USe: Volclay®Grout is designed for use in sealing well casings and de- <br />~ commissioning abandoned wells and boreholes, and sealing closed <br /> loop heat pump systems. It forms a low permeable, flexible seal. <br /> <br /> Characteristics: o Single component for 1-step mixing, no initiator is needed. <br />`' o Low permeability, laboratory tests range from 1 x 10'' to 1 x lo-8 <br /> cm/sec. <br /> o Laboratory test range pH from 5 - 6. <br /> o X11 not damage well casing, no heat generated during mixing or <br /> curing. <br />L. o Remains flexible, maintains putty-like consistency over time and <br />' will rehydrate. <br /> o Physically stable, will not flow through highly permeable soils, <br />• o Longer placement time than with bentonite polymer grouts. <br />~_ o Can be positively placed using tremie pipe method ensuring <br /> uniform, consistent application. <br />' Mixing and <br /> Application: Add SO lbs. of Volclay®Grout to 23 gallons of fresh water to produce <br /> 3.5 ft' of grout. This is a 1-step grout and NO RVITIATOR IS NEC- <br />' ESSARY. For best results, the grout should be mixed with a venturi <br /> type jet hopper or commercial grout mixer. Volclay®Grovt remains <br /> placeable for at least two hours. The grout should be pumped <br /> through a side discharge tremie pipe or other applicable method <br />•- which displaces the grout from the bottom of the well up to the <br />' surface. Pumping should continue until the grout purged to the <br /> surface is at the proper mud weight of 9.41bs./gallon. <br />'' Packaging: SO lb. multi-wall, paper bag, 48 bags per pallet. All pallets stretch- <br /> wrapped. <br />1 <br />
