We work alongside Type B systems, and combine systems that include Type B. We can tie in our Type A and Type C systems alongside a Type B system. 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:

Most adaptable for projects that include:

• 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:

• Contaminated Water entering the system.

• Ensuring the external basement wall provides enough primary resistance to water ingress to ensure the cavity accepts only a controlled amount of water or dampness

Type C Waterproofing Systems will fail if water is allowed to exert a head of pressure on the system. A failure in the waterproofing system proves costly, accounting for up to 80% of construction litigations and repairs
