The Paper describes volume change properties of the more important British clay soils. Seasonal variations in soil moisture and the significant reductions that trees can induce are discussed. The impact of the 1975–76 drought in Britain which generated many cases of building damage is considered by the application of a damage classification, the results of which suggest that levels of damage have not generally been large. However, the large heave movements which can occur close to trees following their removal are emphasized. Recently published information on the range of influence of various tree species in clays in urban conditions is reviewed and a hierarchy of damaging trees is presented. Some consideration is given to the difficulty of detecting desiccation in clays, with some practical though limited guidance being suggested. Three short case histories are presented to illustrate the influence of trees on both existing buildings and new construction. Cet article decrit les proprietes de changement d...
