The process involves injecting a stiff mortar-like grout into the ground to displace and compact the surrounding soil. During injection, the grout displaces the soil and forces the soil grains into tighter packing, expelling air and/or water out of the effected area, and reducing pore volume.

During the latter 1950s the use of low mobility grouts for void filling had become common. The use of these plastic consistency grouts was further extended to jacking of
