Nicholls Lane, Stone, Staffordshire

The challenges of limited space and the presence of existing services were overcome by installing Secura Grand using the geopin method.

Geopins reinforced the existing soil and did not require the retained mass to be excavated and replaced as with geogrid reinforcement.

The geopin reinforced Secura wall is ideal for use on sites where backfill space is limited or where it is preferable to avoid the greater amount of excavation which is required for a geogrid reinforced or concrete backfill wall.  As the location of the services was identified, 50 geopins were installed avoiding any distribution to the services. The groundworkers were pleased to discover the wall which was 3.2 metres at its highest, was quicker to construct with geopins compared to geogrid as placement and compaction of layers of fill is avoided.

Secura Grand enabled two adjacent walls with a consistent look despite the different construction methods and ground stabilisation for each case.

Tobermore also provided fully indemnified permeable paving using Hydropave Tegula Duo complemented with kerbing.
