Low-rise building foundations: the influence of trees in clay soils

Digest 298

BRE, 1999
Low-rise building foundations: the influence of trees in clay soils

Document Status



Core Supplement




Soil shrinkage caused by the removal of water by trees and other vegetation can result in foundation subsidence. Soil swelling caused by the recovery of moisture following tree removal can result in foundation heave. This digest gives simple design guidance on minimising these effects in clay soils and points to some dangers in current foundation practice.


Should be read in conjunction with Digests 240, 241, 251 and 412.
