This is a comprehensive and invaluable guide to the provision of all-weather surfaces for horses which covers the choice of site, drainage, construction, materials, and maintenance, as well as a chapter on the common causes of failure and how to correct them. New developments of major significance are: a patented arena base system which has been installed as part of the provision of an arena for a well-known dressage rider and the continuing development of a patented turf reinforcement system, which has now been introduced at many venues, including Smith's Lawn polo grounds.
