Geofoam, The Lightweight Fill

Tru-R Geofoam is engineered to give you the greatest possible control for your project application: from design and timelines, to materials and costs, and control over your results.

The advantages to using Tru-R Geofoam include:

  • Predictable material behavior
  • Manufactured to meet ASTM D6817
  • Variety of Types to meet specific project requirements
  • Super lightweight compared to other fills
  • Inert in long-term burial conditions, no leachates

Tru-R Geofoam means control, not compromise.

Traditional earth materials are heavy and can cause settlement, instability or lateral pressures. Other fill materials such as foamed concrete, waste tires, soil, woodchips, wood fiber, etc., have higher densities, are variable in their makeup and are not engineered, due to field execution variables. They also have limitations in handling and can be weather sensitive, thus requiring staged construction and/or preloading, surcharging and draining, etc. Tru-R Geofoam maximizes onsite installation efficiency. Material can arrive at the job site prefabricated and ready to place. It is easily inventoried and handled. Installation is not delayed by weather.

Geofoam Applications

Stadium Seating

The theater viewing experience enhances every great performance.  Tru-R Geofoam has been used to cost effectively transform movie theaters, public outdoor venues, school auditoriums and private viewing rooms into environments where people become immersed in the performance.

Retaining Walls

Reducing lateral loads on retaining walls, reduces costs of construction, as well as insuring long term performance.  Using Tru-R Geofoam provides the most reliably engineered, fast construction method to build high performance retaining walls.

Lightweight Roads

Transportation roadways often need to be built over unstable soils. The use of structural, light weight Tru-R Geofoam reduces construction time and the costly steps of surcharging, de-wicking and driving piles.  Tru-R Geofoam delivers fast, stable and built within-budget road building.

Bridge Abutments

Tru-R Geofoam used in the approach fill sections of bridge construction, reduces lateral loads on the bridge deck support system, which reduces cost.  Tru-R Geofoam also prevents the potential deferential settlement of the finished roadway and the bridge deck elevation.

Plaza Decks

Reducing over bearing loads on plaza decks increases deck spanning distances at lower cost.  Tru-R Geofoam allows for cost effective long span designs.  And, Tru-R Geofoam’s insulation power allows for conditioned habitable space under the plaza deck.

Vegetative Roofs

Foundation Fill

Foundations over unstable or expansive soils is a challenge.  Tru-R Geofoam allows for soil removal and replacement, with light weight Tru-R Geofoam structural fill. This provides for a net zero weight gain for the structure, on the building foot print.

Utility Protection

Overbearing fill and roadways, reoccurring live loads and consolidating soils can cause damage to underground utility service runs.  Tru-R Geofoam relieves these stresses and protects critical utility runs for years to come.

Slope Stabilization

Mobile soils, cyclical surface and sub-surface water events can effect the stability of roads and structures, built on natural slopes.  Designs using Tru-R Geofoam can provide an engineered solution that eliminate slope erosion, and stabilize the native conditions.

Building Fill

Urban redevelopment and reclamation of historical buildings, requires adjustments to floor and stair elevations to meet code egress, HVAC, and electrical standards. Tru-R Geofoam elegantly and cost effectively provides the solution for urban building retrofit.
