Why bring in a waterproofing specialist early?

Ownership of the structural waterproofing design is often unclear on a project. BS 8102:2022 expects a waterproofing specialist to be appointed before the technical design stage at the very latest (think ‘late’ RIBA Stage 3). Involving us at concept and spatial design stage means questions of grade, system choice and buildability are settled while they are still cheap to answer.

RDA-UK design and review below-ground waterproofing for the UK construction industry, in line with BS 8102:2022, so that the protection specified on paper is the protection that can actually be built on site.
