Tensar's retaining wall used for Asda parking

Tensar International's Tensartech earth retaining technology has been utilised to create customer parking under an ASDA store with a sloping site.

Parking for more than 500 cars and the goods delivery yard was created at less cost and time than with traditional construction methods at the superstore in South Shields, Tyne and Wear.

It was created underneath the store to reduce land grab within the retail complex.

The 100m long and 6m high Tensartech TW1 wall has been installed to enclose two sides of the undercroft car park, with the main store located on the mezzanine above.

The sloping site topography meant that the rear service yard had to be built up to the level of the mezzanine.

By using Tensar's solution, which has BBA certification for a 120 year design life, a retaining structure was created without any requirement for extra foundations.

In addition, this saved cost of construction and time on the overall installation.

The 6m deep retaining structure was constructed from Tensar uniaxial geogrid, layered with imported aggregate to ensure maximum stability.

The geogrids were secured with unique polymer connectors to the TW1 split-faced, concrete modular blocks, providing an attractive appearance.
