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.

Load Reducing Fill
Recurring settlement issues at this bridge approach were solved by replacing a portion of existing soils beneath the approach slabs with Geofill LD Class II Cellular Concrete.
Because Geofill LD is lighter than traditional subgrade, it reduced the load on underlying soils to help prevent future settlement. Geofill LD Cellular Concrete can range in densities from 20 to 60 pcf.
