A schematic of a grout curtain, see drill holes and grouted area.
Grout curtains are barriers that protect a dam from seepage and can be used in initial construction or repair.[1] Additionally, they can be used to strengthen foundations and contain spills.
Characteristics
A grout curtain usually consists of a row of vertically drilled holes filled with pressurized grout, a process commonly known as pressure grouting.[2] The holes are drilled in intervals and in such a way that they cross each other, creating a curtain.
Method
Grout is injected with grouting jets, which use a high-pressure fluid stream (i.e., slurry or water) to erode a cavity in the soil.[1]
