Bastion No. 1 
Gosport

This was a slip in the old Napoleonic defences at Gosport. After thorough research and a site investigation involving boreholes through the crest and along the edge of the slip together with a topographical survey, it was decided to stabilise the slip by using soil nails at the toe and replacing the slipped material with gravel reinforced with a geotextile mesh. The work was carried out to the satisfaction of English Heritage.
