GeoSpan® Compressible Fill
EPS Geofoam Compressible Fill Material
Expanded polystyrene fill material engineered to compress under load, reducing the forces that swelling soils place on structural elements.
Product Details
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.
-
Designed specifically to meet the structure requirements for each application.
-
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
-
Not affected by the presence of water on the short term nor is it dependent on the presence of water in the long term.

Material Properties of GeoSpan® Insulation
| Required Project Data for GeoSpan Design | |||
|---|---|---|---|
| Structure Depth | Structure Weight | Soil Swell | Structure Uplift Capacity |
| A | B | C | D |
A = slab thickness - mm (inches)
B = self-weight of the structure - kPa (psf)
C = long term upward movement of soil beneath structure - mm (inches)
D = structure uplift capacity = maximum GeoSpan compressive stress
GeoSpan thickness (t) is determined using the equation:
t = Soil Swell (mm) x 100
