SHUR-GROUT

 

SHUR-GROUT is a patented formula bentonite product designed to be used as a water well grouting fluid, drill hole

abandonment fluid, grout for geotechnical monitoring wells after casing   placement, and  other geotechnical

construction applications  requiring non-destructible subgrade seals. Once in place, SHUR-GROUT   begins to set

and assumes a caulk-like consistency that   contacts formations  to establish a low permeability seal (1 X 10-9 cm/sec).

 

MATERIAL SPECIFICATIONS:

    Dry Fineness: 80% min. passing a 200 mesh screen

    Processed Bulk Density: 58.0 ± 4 pounds/cubic foot

    pH: 5% slurry, 8 to 9.8

    Slurry Density: 10.2 pounds/gallon at 30% solids

    Permeability: 1 x 10-9 cm/sec

SHUR-GROUT can be mixed and placed using most available pumping

equipment. Although type mixers and positive displacement pumps

work best, mixing can also be done through recirculating systems.  

Maximum performance is achieved at a ratio of 1 bag to 14 gallons of water (30% solids). Since pumps such as

double diaphragm or gear pumps may not produce enough pressure to place highly viscous mixtures, the ratio

can be adjusted to 1 bag per 16 gallons of water and still achieve a good grout "set".  As SHUR-GROUT is added

to the make-up water, a "pan-cake batter" consistency is generated. Pumping at this time is recommended as

it minimizes migration into formations and allows for continued hydration to take place down hole. Provided local

regulations allow, it is always recommended to with-draw the tremie line as grout is being pumped. This permits the

grout to continue its "set" undisturbed, reduces pump pressure and minimizes unnecessary migration into formations
