GeoVoid® Compressible Fill
Compressible medium under structural concrete floors
GeoVoid compressible fill material is an expanded polystyrene product designed to act as a compressible medium between swelling soils and structural elements. Where long-term soil movement can be predicted, GeoVoid compressible fill material can be designed to reduce the forces that would be induced on structures by soil movement, thus reducing the likelihood of damage to the structure above. GeoVoid design for each application is based on the thickness and depth of the GeoVoid compressible fill material which is unaffected by water, does not support vermin or insects, and the dimensions can be easily adjusted on the job site.
GeoVoid compressible fill material properties assist designers in addressing the following code requirements:
- GeoVoid compressible fill material is designed specifically to meet the structure requirements for each application.
- GeoVoid is available in a range of compressive resistance to permit design for light structural to heavy structural elements.
- GeoVoid design criteria are provided for each application in the design summary for review by the engineer.
- GeoVoid is not affected by the presence of water on the short term nor is it dependent on the presence of water in the long term.
