Geofoam
Geofoam is an EPS (Expanded Polystyrene) block that has been used as a geotechnical material since 1960. The weight of geofoam is approximately 1% of the weight of the soil and 10% of the weight of other lightweight alternative fill materials. As an extremely lightweight soil filler, geofoam can reduce the load on the soil or structures beneath it. In addition to being a very lightweight soil filler, the use of geofoam is also highly advantageous in terms of time and cost of work. Geofoam can be cut to the desired volume design and is easy to install in the field. Geofoam used as a soil filler must meet the geofoam standards set by ASTM D-6817.
Advantages of Geofoam include:
- Lightweight
- Easy field installation: Geofoam does not require heavy machinery for installation. Its lightweight nature allows for easy and quick installation in the
field - Fire retardant: Geofoam is designed to be fire retardant, reducing the risk of fire-related hazards.
- Time-saving: The use of geofoam can greatly reduce construction time due to its easy installation process. It eliminates the need for complex and time-
consuming construction methods. - High compressive strength: Despite its lightweight nature, geofoam has a high compressive strength ranging from 15 to 128 kPa/m2. This allows it to provide structural support and stability.
- Termite-resistant: Geofoam is resistant to termites, preventing any damage or degradation caused by these pests.
- Long-lasting: Geofoam is non-biodegradable, ensuring its durability and longevity over time. It does not decompose or degrade, maintaining its structural integrity.
- Utilizes Galvanized GeoGripper: The use of Galvanized GeoGripper enhances the installation process of geofoam by providing a secure grip and stability.
