GeoSpan

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.
