ICS 91.120.30

CED 41

Reaffirmed 2022

1. Scope

This standard lays down recommendations and provides guidance on methods of dealing with and preventing the entry of water from surrounding ground into a structure below ground level. It covers the use of,

a) waterproofing barrier materials applied to the structure,

b) structurally integral watertight construction, and

c) drained cavity construction.

It also covers the evaluation of groundwater conditions, risk assessment and options for drainage outside the structure. It applies to structures which extend below ground level and those on sloping sites.

This standard does not give recommendations concerning the use of embedded heating in structures, floors and walls or for the special requirements in connection with the design and construction of cold stores.

NOTE - Structures are generally characterized as deep, if they have more than one storey below ground level, or shallow, if they have only a single storey below ground. This standard is applicable to both.
