Waterproofing Below Ground: Grades, Protection Types and Combined Systems

This course explains how BS 8102 grades and ground conditions set the design, compares barrier, structurally integral and drained protection, reviews sheet membranes and bituminous, cementitious and crystalline coatings, and covers the joints, sequencing, protection, testing and repairs that keep a basement dry.

Learning objectives

1. Explain the grades of protection for below-ground spaces and how groundwater, ground chemistry and intended use set the design
2. Compare barrier, structurally integral and drained protection, and decide when to combine them
3. Select barrier materials, including bonded sheet membranes, bituminous coatings and cementitious and crystalline coatings, for positive-side and negative-side application
4. Specify the details, sequencing, protection and inspection that decide whether a below-ground structure stays dry
