GeoSpan® Compressible Fill

GeoSpan 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, GeoSpan 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. GeoSpan compressible fill material is unaffected by water, does not support vermin or insects, and the dimensions can be easily adjusted on the job site.

GeoSpan Compressible Fill material supports expected construction live loads, & the weight of the structural slab until the concrete has cured and gained enough strength to be self-supporting. GeoSpan acts as a compressible medium for applications such as under concrete grade beams, structural floor slabs, & against foundation.

Why GeoSpan® Compressible Fill

• GeoSpan compressible fill material is designed specifically to meet the structure requirements for each application.
• GeoSpan is available in a range of compressive resistance to permit design for light structural to heavy structural elements.
• GeoSpan design criteria are provided for each application in the design summary for review by the engineer.
• GeoSpan 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.
