Specifically formulated for geotechnical and underground applications, Geofill LD is a low density cementitious material that contains no aggregates. Densities and strengths can be formulated to match individual project needs.

Geofill LD Material Characteristics:
Low Density – With Geofill LD, load reduction can be achieved without sacrificing strength or stability making it ideal for reducing vertical loads over weak soils or underlying structures and lateral loads against MSE Panels and retaining walls.
Highly flowable – Geofill LD can be pumped for long distances at low pressures. This is an excellent material for completely filling abandoned lines or annular spaces due to its self leveling characteristic.
High Bearing Capacity – Lightweight – yet stronger than many soils or compacted fills – Geofill LD is frequently used as an embankment and bridge approach fill on highway projects.
Excavatable – Ease of re-excavation makes Geofill LD an ideal choice for open cut backfill projects when weight is an important consideration.
Pumpable – High air content makes it easy to pump Geofill LD long distances at low pressures.
Clark/Elsinore Rd Water System Perris, CA
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.
