Book Description
This Good Building Guide discusses one of the main challenges when designing a basement: preventing water or water vapour ingress. The focus is on dampness due to penetration of groundwater, sometimes complicated by rising damp. Part 1 (6 pages) outlines the principles of constructing a waterproof basement. Part 2 (6 pages) describes the main methods for perimeter construction with advice on safety, insulation and services.
