POLYSTYRENE FOR STRUCTURAL & EARTHWORKS APPLICATIONS

Retaining Walls Parking Structures Foundations Berms Embankments Landscapes Green Roofs Levees Dikes Utility Protection Compressible Inclusion The use of polystyrene in earthworks and structural applications provides the benefit of reducing both vertical and lateral pressures on below-grade structures. Soil creates nearly 6.3km/m3 of lateral pressure. If a structure is below ground level, this lateral pressure increases by a factor of 10. The use of polystyrene completely eliminates this lateral pressure. The use of polystyrene for earthworks and structural applications is easy to install, does not require surcharging, pre-loading or staging and is a cost-effective engineering solution.

Expanded Polystyrene Foam ( EPS) can be used as lightweight fill in the construction of roadway embankments in the area overlying the toe drain. Terrafoam would be located over the toe drain area to reduce the stresses and associated settlements induced by embankment loads.

Terrafoam EPS is an engineered thermal plastic material that is factory manufactured to exacting product standards. It has strength characteristics equal to a well-compacted soil fill, but with only 1 to 2 % of the weight of soil. Typical compacted soil fill is often estimated to have a unit weight of 20 Kilonewton per cubic metre, while the Terrafoam EPS exhibits a density of only 0.32 Kilonewton per cubic metre. It is manufactured in large blocks that are easy to handle and install. A major benefit of Terrafoam EPS is that it can be installed under any weather conditions. The Terrafoam EPS can be capped by a geomembrane liner to protect it from hydrocarbon attack;


in the event such a spill occurred. Standard construction techniques are permitted to take place over the installed Terrafoam EPS subsequent to it being covered by soil embankment materials of sufficient depth.

The Contractor responsible for the Terrafoam EPS installation and embankment construction, should installs by staggering the block layers and using a multi-barbed Gripper plate or glue to pin the layers together

YOU’RE IN CONTROL WITH PIL EPS.

PIL EPS building products are engineered to give you the greatest possible control for your project application: from design and timelines, to materials and costs, and—ultimately—control over your results. The advantages to using PIL EPS products include: • State-of-the-art insulation and energy efficiency• Variety of density, thickness, size• UL QA monitored, tested, certified, listed• Unlimited fabrication possibilities• Building code recognized• Warranted R-value• Perform Guard® termite protection available• Cost effective• Long-lasting, strong, and stable• Contains no CFC, HCFC, HFC, or

formaldehyde• Recyclable PIL PS is a lightweight yet strong material that gives architects, designers and builders the freedom and confidence to turn their visions into reality.

This looks like a job for expanded polystyrene.

In the construction industry, PIL EPS is among the most versatile, energy efficient, and cost effective insulators available, delivering extremely high, stable

R-values. Depend on PIL EPS supply to do the job—practically any job—from the ground up: perimeter foundation and underslab insulation, wall sheathing, EIFS insulation, roof insulation, concrete insulation/void filler, ICF insulation, Terrafoam and just about any construction application you can imagine.

Good for the environment. Cost effective thermal design is among the highest priorities

in construction. PIL EPS insulation products are available in a range of densities necessary to provide energy efficiency, structural integrity, and cost effectiveness. They’re proven to lower energy costs, saving both money and precious resources.

Be the master of your materials.

PIL EPS, when used as a component in an engineered building system, helps to resist some of the toughest conditions nature can deliver, like rain, snow, wind, dust, heat and cold.

Proven to meet, or exceed, building codes. PIL EPS is manufactured to Quality Control Program standards and recognized by national building codes.

Polystyrene (EPS) Solutions

Slope Stabilization

Polystyrene engineers recognize the validity of using expanded polystyrene (EPS) Terrafoam as lightweight fill to reduce mass and associated gravitational driving forces within sloped embankments. The detail below illustrates a typical slope stabilization application using PIL lightweight fill material. PIL EPS Terrafoam with a density from 15 to 35 kg/m3 is up to 100 times lighter than in-place soil with a typical density of 2,100 kg/m3. This means that replacing in-place soil in an unstable slope with EPS Terrafoam can achieve a significant net reduction in driving force within the embankment

Figure 1 – EPS Polystyrene Placement in Slope Stabilization Application

Terra foam EPS is often the best option for lightweight fill material in embankment construction because it is up to 100 times lighter than soil.

When side slope failure occurs in road applications, it is often the result of subsurface soil with low load-bearing capabilities. Often in this type of situation makeshift repairs are implemented by filling and resurfacing the failed road section.

(Figure 2). This is a performance solution to reconstruct a section of highway, which had been subject to reoccurring side slope failure. The normal practice here is that a section of highway has been repaired unsuccessfully a number of times previously by filling and resurfacing the failed road section. In this instance, the side slope had failed resulting in a portion of the road surface dropping.

To provide an improved slope safety factor against failure, the corrective measure to be taken is to excavate the section of road down to hardpan. PIL lightweight fill material blocks were supplied to replace a portion of the failed soil embankment (Figure 3).

The blocks are delivered to the site on flat bed trailers, unloaded and then placed in their final position on the prepared roadbed by hand. The road construction crew backfilled over the PIL lightweight fill material as they were placed.
