Pile Mat Design, Plymouth

Geogrids were used as part of a pile mat design for a site in Plymouth.

Calculations, which were undertaken in accordance with BRE 470: working Platforms for Tracked Plant, showed that a significant reduction in the platform thickness could be achieved if geogrid was incorporated into the platform construction, reducing the temporary works costs.

Calculations were carried out for geogrids of varying tensile strength so that cost-benefit analyses could be carried out.
