Stabilisation - Abweb and Abgrid, Quarry Bank Mill, Styal, Cheshire, UK

Quarry Bank is an old cotton mill in Cheshire, now operated by the National Trust it attracts large numbers of visitors daily. A permeable run off was required to allow the car park to be used without issue all year around as there had been problems with saturation previously. A solution was required without having to replace the first lift of soil that was already down. To stabilise the soft spots, Abweb back filled with the existing cappings meant further excavation was not required. Abgrid and Trigrid enabled the target CBR to be met with 30% less sub base needed.
