Type B : Structural Integrity Protection
We are structural waterproofing and ground gas protection contractors. All of our installers are trained and experienced in the installation of our specialist materials
Structural Integrity Protection — Simplified:
Type B (structurally integral) protection as defined by BS8102:2022 (Code of practice for protection of below ground structures against water from the ground) where the structure itself is constructed as an integral water-resistant shell
.
Explained:
Type B (structurally integral) protection as defined by BS8102:2022 (Code of practice for protection of below ground structures against water from the ground) where the structure itself is constructed as an integral water-resistant shell. Invariably built of reinforced concrete, the basement structure must be designed within certain strict parameters to ensure it is water resistant.
When considering and or specifying a Type B integral system, this should only be carried out where there is knowledge and understanding of waterproofing in relation to BS 8102: (2022) and in the case of concrete structures an understanding and competence in concrete construction.
The water tightness of the Type B construction is reliant upon the design and construction of the basement as an integral shell, using a concrete of low permeability, and appropriate joint detailing.
Defects can be minimised by correct specification and design and by careful construction
Area of use:
New build basements.
Any new Underground Structures.
Below ground structures.
Car parks.
Retaining walls.
Swimming pools.
Lift pits.
Tunnels.
A concrete structure that is designed to experience and resist the penetration of water under pressure
What you should consider:
Type B should not be relied on for Podium Decks without secondary protection
Type B waterproofing should be installed by suitably experienced and trained operatives who are fully aware of the requirements for placing concrete used in Type B systems
- A risk assessment should be carried out which identifies any possible long-term water pressures, the effects of surface water percolation, use of external drainage and the effects of party wall impaction on neighbours
- The design of the waterproofing system should consider the likely effects of these ground conditions, including water, and assume exposure of the basement to full height of water within the design life of the building
Type B systems can NOT provide methane or radon resistance as a standalone system unless incorporating a membrane
- We recommend using ready-mixed concrete suppliers operating under the quality scheme for ready mixed concrete (QSRMC) or BSI Kite-mark scheme only
