AbstractAn investigation of the incidents of trees causing building subsidence was undertaken as a re-investigation of the data reported in the Kew Root Survey undertaken by CUTLER and RICHARDSON in 1981, and expanded in 1989. This investigation was undertaken 26 years after the Kew Root Survey was first reported. The databases of the major loss assessor (Cunningham Lindsey UK Ltd); the site investigation company (The CET Group Ltd); the tree root identification Labs (Tree Root Investigations Ltd) and the major arboricultural consultancy company involved in subsidence (OCA UK Ltd) were interrogated. The study reveals that although there are some minor differences between the data reported in the Kew Root Survey of 1981 and the data in the present study, the findings of the Kew Root Survey are vindicated. A discussion about tree rooting strategies is included because of the historic reliance that Arboriculturists and others place on the straight line distances between trees and building damage. |
