THE PROBLEM
There was a tight programme on a difficult sloping site which needed to be split into tiered levels. Site access was restricted due to the existing adjacent landowners.
THE SOLUTION
The TensarTech TW1 modular block retaining wall system offered a stable, fully indemnified design and an attractive appearance, providing a pleasing split faced architectural finish.
PROJECT DESCRIPTION
TensarTech TW1 Wall Systems are BBA certified systems offering up to 120 years design life. 250m2 of retaining walls were installed with a maximum height of 3.5m. Imported granular fill was placed and compacted behind the face reinforced with layers of Tensar uniaxial geogrid which were attached to the facing blocks using high efficiency mechanical connectors. The blocks are dry laid and placed by hand. No crane lift or temporary propping is necessary. These walls enabled effective use of tight space throughout the site with retaining walls forming both the upper and lower boundaries. The gardens of the lower houses were then formed on the newly created plateau areas.
