Low Density – With Geofill LD Pervious, 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. Best of all it is free draining.
Highly Flowable – Geofill LD Pervious is an excellent
material for open cut backfill projects due to its self leveling
and pervious characteristic. It will easily fill around and
into hard to reach areas.
High Bearing Capacity – Lightweight – yet stronger than
soils or compacted fills – Geofill LD Pervious is frequently
used as an embankment and bridge fill on highway projects
where a free draining, lightweight material is required.
Excavatable – Ease of re-excavation makes Geofill LD Pervious an ideal choice for open cut backfill projects when weight and drainage are important considerations.
Pumpable – High air content makes it easy to pump Geofill LD Pervious long distances at low pressures.
The latest advancement in low density cellular concrete, Geofill LD Pervious is ideal for applications that require a combination of strength and high permeability.
This new product is very similar to Class I and Class II Geofill LD cellular concrete in weight and strength. What makes this material unique is its ability to allow water to freely drain. Geofill LD Pervious has densities ranging from 20 to 30 pounds per cubic
foot. It is primarily used as a load reducing fill where drainage is needed.
Lower Northwest Interceptor Sacramento, CA
Annular Space Grouting
This project consisted of a 19-mile sewage conveyance pipeline and pump station system that required micro-tunneling methods to install the new lines anywhere pipe could not be installed in an open-cut trench, such as under the Sacramento River or I-80.
The micro-tunneling operation was completed by filling the annular space around the pipe with Geofill LD cellular concrete to prevent corrosion and movement. This flowable material also reduced potential flotation or collapse of the carrier pipe.
