The New Wembley Stadium

Geotechnical Observations were involved from the beginning of this project, making on site suction measurements to assess the best compaction conditions to manage the highly expansive London Clay. To monitor the ground movements following the compaction GeO installed 50m deep rod extensometers and 30m deep magnet extensometers, with VW piezometers being used to monitor the dissipation of excess pore water pressures and inclinometers being used to monitor the deflection of bored piles used to retain the swelling clay.
