Geogrids are used increasingly to reinforce unpaved roads and trafficked areas. As in the case of a temporary overflow car park, when the protection of the grassed area is required, then TENAX LBO geogrids reinforcement are well suited for this application.
Geogrids help to prevent shear failure in the sub-grade and reduce rutting to a minimum.
The design consists of placing the geogrids over the grassed or trafficked areas and fixing with 'U' shaped pins, an overlap of 300 mm usually is required.
Grass will then grow through the apertures of the TENAX LBO geogrid, thus forming a stable reinforced ground crust. If however the requirement is temporary then the TENAX LBO geogrid can be easily rolled back and re-used in other applications.


problem
During the peak summer holiday season, traffic becomes much busier at Gatwick Airport, bringing with it a requirement for extra car parking space.

The airport operator approached the contractor John Laing Construction for a solution which was both economical and fast in order to provide temporary parking space for the general public using the airport.
