BS 8102:2022

In the world of waterproofing, BS 8102:2022 is like our Bible. It provides rules and recommendations that help us keep buildings dry and safe, especially basements and underground structures.

What is BS 8102:2022?

BS 8102:2022 is a British standard that outlines how to prevent water from seeping into below-ground structures. It categorises waterproofing systems into three main types based on water exposure risk and management:

  1. Type A (Barrier Systems): These systems create a physical barrier to water ingress. They include materials like cementitious coatings, bituminous membranes, or liquid-applied membranes applied to the structure’s internal or external surfaces. Type A systems are effective where there’s a low to moderate risk of water ingress.
  2. Type B (Structurally Integral Protection): Type B relies on the inherent waterproofing properties of the structure itself. This often involves using specially designed concrete mixes or additives that make the concrete impermeable. Type B systems are suitable for structures where a high level of water resistance is required.
  3. Type C (Drained Protection): Type C systems manages water ingress as it allows it to penetrate the structure and directing it away safely. This is achieved through cavity drain membranes or drainage channels that collect and redirect water to suitable discharge points. Type C systems are ideal for structures with high water ingress risks or where maintaining internal dryness is crucial.

Why is BS 8102:2022 Important?

  1. Planning for Risks: Before starting any project, BS 8102:2022 helps us assess risks like groundwater levels and soil conditions. By understanding these risks, we can choose the best combination of waterproofing systems. Such as, using a Type A system alongside Type C drainage for ensuring comprehensive protection.
  2. Design and Building Together: The standard emphasises integrating waterproofing into the building design from the outset. This collaborative approach among architects, engineers, and waterproofing specialists ensures that the construction work together, seamlessly to prevent water ingress.
  3. Keeping Things Working: After installing waterproofing systems, BS 8102:2022 recommends regular maintenance and monitoring. This proactive approach promptly identifies and addresses issues like barrier cracks or drainage blockages, maintaining waterproofing effectiveness over time.
  4. Helping the Environment: Effective waterproofing not only protects buildings but also reduces the environmental impact by minimising waste material. BS 8102:2022 encourages sustainable waterproofing practices that contribute to building resilience and environmental stewardship.
