Cellular concrete is a very easily pumped, highly fluid mixture. The bulk of cellular concrete is placed by pumping. Cellular concrete typically will move through the pump lines using less pressure than typical heavier grout mixes. Cellular concrete can be pumped up to and exceeding 500 ft. vertically and 10,000 ft. horizontally is commonly available.
Typically, Geofill Cellular Concrete is placed in 2' to 4' lifts depending on cell size. In most cases, nothing is done between lifts. Occasionally we see a specification that requires a scarification, but this is rare. This material is similar to soils, not concrete.
In most cases, you must dewater before placing material. There must be enough load on top of our material to prevent uplift. Use of the Geofill-LD Pervious will help to reduce overall buoyancy.

Filling Abandoned 12” Pipe
Rebuilding the infrastructure of California’s 5th largest water district involved filling more than three miles of 12” abandoned water lines. The lengths of pipe to be filled ranged from 1,000 to 3,500 feet.
Geofill LD Class II was used because -- unlike CDF or sand cement slurry -- this flowable material can be pumped distances of up to one mile at low pressures without requiring multiple access points.
