Speak To An Expert

CSSW Waterproofing Design

Our designs are led by CSSW (Certified Surveyor in Structural Waterproofing) professionals, recognised within the industry and by warranty providers as competent waterproofing designers.

We can:

  • Develop a project-specific waterproofing strategy
  • Select appropriate protection types (Type A, B, C or combined systems)
  • Coordinate with structural and architectural design to avoid conflicts
  • Provide written design statements and drawings for submission to Building Control, warranty providers, and insurers
  • Offer design sign-off confirming compliance with BS 8102:2022 and relevant technical standards

Having a named CSSW designer involved from the early stages significantly reduces the risk of future water ingress and associated claims.

Our Design Approach

We take a pragmatic, risk-based approach to waterproofing design:

  1. Site & Risk Review
    • Review ground investigation data and groundwater conditions
    • Understand proposed use of the space (habitable, plant, storage, etc.)
    • Identify risk level and required performance (Grade of internal environment)
  2. System Selection
    • Evaluate options for Type A (barrier), Type B (integrated), and Type C (drained cavity) protection
    • Consider combined systems where risk or consequence of failure is high
    • Select materials and systems suitable for the structure and build sequence
  3. Detailing & Integration
    • Design critical details (joints, penetrations, pile caps, retaining walls, podiums)
    • Coordinate with structural engineer and architect
    • Ensure the design is buildable and verifiable on site
  4. Documentation & Support
    • Provide design drawings, details, and a written design report
    • Support you through queries from contractors, warranty providers, or Building Control

Backed by £5 Million Professional Indemnity Insurance

All waterproofing designs produced by UKRS are covered by £5 million Professional Indemnity insurance.

This gives:

  • Developers & clients – reassurance that design liability is backed by substantial cover
  • Contractors – confidence in following a professionally insured design
  • Funders & warranty providers – clear evidence of competent, insured design input

We understand the commercial and legal importance of accountability in waterproofing design, and our PI-backed service reflects that.
