Lateral Finger Systems
New life for your septic system in one day without disturbing your lawn!
Terralift™ uses a long, narrow probe and an integral pnuematic hammer to penetrate soil to the depths of three to six feet – depending on the depth of your drainfield. It then forces air into the soil at a controllable rate using a high pressure compressor creating a network of fissures and cracks which break up the biomat that has formed on the walls of trenches, and loosens compacted soil in the drainfield as shown.
Because air tends to follow the path of least resistance, the air will move horizontally and vertically upward through the soil. This process is repeated every four feet (depending on soil conditions) around each of the drainfield trenches (as indicated below.)
