| Pressure Grouting | |
|
We employ a system which requires the pumping of cement, sand and PFA grouts to fill the voids. Where necessary, barriers can be formed by injecting sand and aggregate into peripheral holes to limit the extent of infill grout to the target area. Applications for this include shallow mine workings, shafts, redundant pipelines, tanks, pits, cellars, basements, culverts, tunnels, adits and voids beneath floor slabs. |

Structural Leak Sealing |
|
|
Leakage of water can be minimized or in some cases completely sealed using pressure grouting methods. This includes drilling - normally through the full thickness of the structure. Cement and/or chemical grout is then injected to form a skin of consolidated strata around the structure. This also has the effect of filling and sealing all major fractures throughout the structure. Where the leak in the concrete occurs through a faulty construction joint or crack, the treatment is confined to the leaking joint or crack. Applications on tunnels, basements, cellars, culverts, sewers, aqueducts, manholes, pumping chambers, locks, dams, reservoirs and embankments. |
