This publication sets out a comprehensive review of tree root biology and covers a broad range of practical issues that need to be considered in order to grow trees successfully in our towns and cities and to realise the significant benefits they provide in built environments. Topics covered include: soil condition and roots; improving tree root growth in urban soils; water supply and drought amelioration for amenity trees; coping with soil contamination; protecting trees during excavation and good trenching practice; control of damage to tree roots on construction sites; tree root damage to buildings and pavements, sewers, drains and pipes; research needs and sustainability issues.

A survey on the damage caused by tree roots which indicates the conditions under which trees can be planted near buildings in safety. It also discusses the identification of tree roots from their anatomical structure and contains new information on some 12,300 tree and shrub root identifications.

Wood is formed in an essentially water-saturated environment in the living tree, and the cell wall remains in this state until the water flow from the roots is interrupted, such as by felling the tree. The wood then begins to lose most of its moisture by drying, resulting in changes in most of its physical properties. These changes, and their relationship to the environment to which the wood is subsequently ex posed, are the subject of this book. The text consists of six chapters. The first chapter discusses cer tain empirical relationships between wood and water, methods of measuring wood moisture content, factors which affect its equilib rium moisture content, and the effect of moisture content on wood strength. The second chapter treats the thermodynamics of moisture sorption by wood, inc1uding enthalpy, entropy, and free energy changes. The third chapter discusses some of the theories which have been proposed to explain the sorption isotherms for hygroscopic ma terials such as wood. Chapter 4 considers hygroexpansion or the shrinking and swelling of wood associated with moisture change. Chapter 5 is concerned with how moisture moves through the cell wall of wood in response to both moisture and temperature gradients. The sixth and final chapter discusses the theoretical and practical aspects of the electrical resistance and dielectric properties of wood, in c1uding the principles involved in their application in electrical moisture meters.

Providing practical guidance for homeowners whose properties have been affected by subsidence, or heave, or who are concerned by the potential risk of damage, this second edition has been expanded to include sections on other types of subsidence and causes of damage that are unrelated to foundation movement.

GSP 115 contains 14 papers presented at sessions of the Shallow Foundation and Soil Properties Committee of the Geo-Institute at the ASCE 2001 Civil Engineering Conference, held in Houston, Texas, October 10-13, 2001.
