Keller nails it for new Derby sports facility

Keller Geotechnique has successfully overcome initial problems on site to complete retaining wall construction for a new £10.8M sports facility and rugby pitch at Derby University.

Despite some early issues of ground collapsing during the benching out of the working platforms and trapped water escaping from the clay fill, Derby-based contractor, G F Tomlinson and Keller Geotechnique worked closely together to complete the works.

Reatining wall contractor Phi has since started work on installing 1200m2 of a stone filled panel system to provide a durable and low maintenance finish to the 65 degree slope.

A total of 596 nails were installed to lengths of between 4.8 to 7.8m founded in re-compacted clays overlying weathered mudstones to secure the ground behind the retaining wall. The retaining wall also consists of sheets of Terram 1000 under A393 mesh held by 300 by 300mm and 400 by 400mm square plates and nuts.
