As the nation's pipeline infrastructure continues to age, more emphasis must be placed on repairing these underground systems.
Sliplining and relining are two solutions that allow the installation of new pipe without having to dig a new trench.
The existing pipe becomes "the host" for a new carrier pipe which is slipped into place.
The annular space between the two pipes is then grouted to protect against shock and corrosion.
The result is a "good as new" pipeline installed at substantial savings compared to traditional installation methods.

This work consists of providing Geofill LD, a non-pervious closed cell, low density cellular concrete to fill the annular space between the host/casing pipe and the carrier pipe from within the carrier pipe or from bulkheads at the end of each section per the plans and accordance with the details in the plans and these specifications.
The annular space shall be completely grouted to support the liner and provide long-term stability and corrosion protection.
Admixtures for water reducing, retarding, accelerating, and other specific properties may be used when recommended by the manufacturer of the foaming agent.

Cellular concrete is generally defined as a "lightweight cementitious material that contains stable air or gas cells uniformly distributed throughout the mixture at a volume greater than 20%."
Cellular concrete can be thought of as a concrete, which utilizes a stable air cell structure rather than traditional aggregate.
No. Geofill cellular concrete weighs considerably less than typical "lightweight" concrete.
By definition "lightweight" concrete is a concrete made with aggregates that are lighter than typical stone aggregates.

Geofill LD cellular (foam) concrete offers significant advantages in projects that require lightweight fill.
Densities can be varied from 20 to 60 PCF and compressive strengths from 50 to 900 PSI.
In addition, Geofill LD is also available in a pervious formulation (Geofill LD Pervious).
Applications include bridging over existing unsuitable weak soils for load reduction, replacement of unsuitable materials, construction of embankments for bridge approaches or ramps, backfilling of MSE panels/retaining walls and open cut backfills.

Geofill cellular (foam) concrete has been used successfully to solve a variety of tunnel backfill grouting challenges.
Geofill's unique set of characteristics makes it an ideal choice for either wet or dry tunnels, as well as critical path projects or jobs where access to injection points is limited.
Geofill LD and Geofill LD Hybrid offer several advantages for tunnel backfill grouting applications, including:.
Mix designs can be customized to project requirements including density, strength, and access issues.
