Terralift is a state approved technological breakthrough in drainfield restoration. It solves a number of soil problems, including: Compaction Saturation Improper drainage The technology of TerraLift allows complete aeration of the septic drain field without disturbing your lawn or other landscaping. The Terra-lift procedure will revitalize your septic drain field in a day or less. Lentz Wastewater Management uses a 6 ft. narrow probe to penetrate the soil around the septic trenches. Once in the ground, it does several things at once: it sends a blast of compressed air into the soil creating new cracks and fissures for liquids to pass through. While the ground is still newly fractured, it sends very tiny polystyrene beads into the new new fractures to keep the new fissures permanently open after the ground settles. These beads are an essential key to the longevity of this process. Because air tends to follow the path of least resistance, both the air and the pellets will move horizontally and vertically upward through the soil.
