BUILDING A WORKING PLATFORM WITH TENSAR INTERAX

PROJECT DESCRIPTION

Tensar were approached to provide a Mechanically Stabilised Layer (MSL) for ground stabilisation, to construct a working platform for piling rig operation.

The challenge was to provide a cost effective engineered solution using recycled material that was generated from within the total site area of 44,000m2. The design proposal was also required to carry all construction traffic operating across the site.

OUR SOLUTION

Following the guidance provided by the Building Research Establishment (BRE) on the use of alternative working platform design methods, Tensar adopted the “T-Value” approach to rationalise the platform thickness, accommodating the request to use recycled material.

The resulting mechanically stabilised platform was constructed using a Class 6N material, placed to the specific depth required, incorporating Tensar InterAx geogrid placed on the made ground formation, which had a Cu value of 50 KPa.

PRODUCT USED

Tensar® InterAx® Geogrid

• Speeds up construction, saving up to 70% in aggregate section reduction
• Optimised geometry design for maximum confinement and compaction of granular fill, creating the most efficient mechanically stabilised layer (MSL)
• Improves compaction and restrict the movement of the particles over time, retaining the stiffness long term and further enhancing performance of the MSL
• Results in a more resilient solution that will withstand severe weather events, the increasing impact of climate change, and other challenging environmental conditions
• Improves interaction between the geogrid and aggregate for better performance
• Less aggregate is required to meet project requirements, which leads to savings on cost, time and carbon emissions
• Ideal for subgrade stabilisation, roads, heavy-duty pavements, and working platforms
