Subsidence Site Tree Surveys

In 80% of subsidence cases (according to the Loss Prevention Council's 1995 Report), trees and/or shrubs are suspected as having contributed to the building's movement due to soil water abstraction by tree roots causing clay shrinkage between the founds.

A Subsidence Site Tree Survey comprises:

  • Vegetation appraisal
  • Root identifications
  • Soil analysis
  • Off-level monitoring
