EXPOL GEOFOAM (S/M/H/VH)

EXPOL GeoFoam (EPS – Expanded Polystyrene) block is used as lightweight fill in problematic situations.

It is multi-functional and is suitable for a wide range of applications, including construction on soft ground, slope stablisation and civil infrastructure work such as bridge abutments, airfield pavements and railway track systems.

EXPOL GeoFoam (EPS – Expanded Polystyrene) is preferred by specifiers and engineers because it reduces construction costs and timeframes, is easy to handle, can be cut on site, and is unaffected by weather conditions.

It offers exceptionally high compressive strength despite weighing only 1% of traditional soil fill and 10% of conventional lightweight fills.

It is made from (EPS – Expanded Polystyrene) beads that have been moulded into blocks, Lightweight fill can be cut into any size or shape depending on the requirement of the project.

As an ultra-lightweight fill the stress on underlying subgrades and adjacent structures is significantly reduced.  It helps improve stability against bearing and slope failures.

EXPOL GeoFoam Foundation

EXPOL GeoFoam (EPS – Expanded Polystyrene) clean waste can be recovered for recycling.

It is ideally suited for use in construction over soft substrates, road embankments, bridge abutments, causeways, retaining wall fill and for replacement of poor soils, landscaping, geotechnical fill, frost heave protection and on sites with limited access.

GeoFoam is manufactured from standard Expanded Polystyrene foam and is available in a variety of grades to suit different construction conditions (see Table 10.2). Typical densities range from 12kg/m3 to 32kg/m3. GeoFoam will absorb small volumes of water, however this will not have a significant effect on its mechanical properties or performance.

Can I get other sizes?

Yes we can cut them down to suit you project.

How durable is EXPOL GeoFoam?

EXPOL GeoFoam is made from expanded polystyrene (EPS), a product that has a long established reputation for resisting degradation over the lifespan of a building.  It is also resistant to soaps and inorganic substances such as dilute acids, alkalis and salt solutions.  EXPOL GeoFoam is not resistant to organic solvents including hydrocarbon fuels and lubricants.

Where is EXPOL H Grade GeoFoam 24kg/m3 used?

It is used under commercial foundations.

Where is EXPOL VH Grade GeoFoam 28kg/m3 USED?

It is used under commercial foundations, driveways and roads.

Where is EXPOL S Grade GeoFoam 16kg/m3 used?

It is commonly used in place of back fill where there is minimal loading such as gardens or lawns

Where is EXPOL M Grade GeoFoam 20kg/m3 used?

It is used under residential foundations.

DOES EXPOL GEOFOAM PROVIDE INSULATION?

EXPOL GeoFoam is suitable for use in protection against frost heave, beneath refrigerated storage buildings and under storage tanks to prevent ground freezing.
