We are offering industrial well point equipmentsif you need of well point method need for groundwater control. Proper control ofgroundwater can greatly facilitate construction of subsurfacestructures founded in, or underlain by, previous soil strata below the water table by:(1) intercepting seepage that would otherwiseemerge from the slopes or bottom of an excavation. (2) increasing the stability of excavated slopesand preventing the loss of material from the slopes orbottom of the excavation. (3) reducing lateral loads on cofferdams. (4) eliminating the need for, or reducing, air pressurein tunneling. (5) improving the excavation and backfill characteristicsof sandy soils. Uncontrolled or improperly controlled groundwatercan, by hydrostatic pressure and seepage, cause piping, heave, or reduce the stability of excavation slopes orfoundation soils so as to make them unsuitable for supportingthe structure. For these reasons, subsurfaceconstruction should not be attempted or permittedwithout appropriate control of the groundwater and(subsurface) hydrostatic pressure.
