Application of Regulation 28 – exemptions for certain building uses
Regulation 28 regarding ground moisture resistance and weather resistance does not apply to buildings used solely for storing goods (with only storage staff) or other purposes where compliance would not increase health or safety protection for occupants.
Regulation 28 in respect of resistance to ground moisture of floors and walls, and weather resistance of walls, shall not apply where the building is intended to be used wholly for—
(a) storing goods, provided that any person who is habitually employed in the building is engaged only in storing, caring for or removing the goods; or
(b) a purpose such that compliance with regulation 28 would not serve to increase protection to the health or safety of any person habitually employed in the building.
