Tensar® InterAx® optimises a platform for student accommodation – big savings for the builder.
Constructed in September 2024.
Benefits
- Reduce platform thickness by 200mm without compromising the platform performance
- Reduce environmental impact with less material import
- Lower construction cost by completing approximately 7 days in advance
As part of the expansion works for this project, piling operations were required but the low strength soils encountered on site meant the working platform needed to support the piling rigs was proving expensive. The contractor had used Tensar before and so approached them for a proposal to reduce the amount of imported fill and the time required to install the platform.
A project specific working platform design was developed using the innovative T-Value approach for a mechanically stabilised working platform incorporating Tensar InterAx geogrid. This reduced the platform thickness by 200mm from the original design whilst maintaining platform bearing capacity requirements to allow piling operations to be successfully completed saving around seven days construction time. Piling operations and other site excavation works were not hindered by the presence of the Tensar InterAx geogrid.
