The use of Stylite EPS Geofill for retaining walls
Stylite EPS Geofill is suitable as a lightweight backfill where a retaining wall is to be built. Because EPS Geofill is very light, the lateral pressures imposed on the retaining wall are significantly less than would be the case with a traditional backfill such as soil.
This in turn means that the retaining wall does not need to be designed to withstand such high pressures if the backfill soil in the active zone behind the retaining wall is replaced with EPS Geofill. This design approach can therefore result in savings in the cost of the structure itself.

Some of the key Benefits of EPS Geofill include:
- Lightweight compared to other fills
- High compressive strength
- Easy to install and cut on-site
- Lower overall cost of construction
- Reduced loads on underlying ground
- Reduced construction programmes
- Available in standard or bespoke blocks
- Minimal water absorption & permeability
- Resistant to rot & durable
- 100% recyclable
- No HFC’s, CFC’s or HCFC’s
