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
