Independent Waterproofing Design You Can Trust

Structural waterproofing design is the process of analysing site conditions, grading performance requirements and specifying systems that protect below-ground structures from water ingress. We assess groundwater behaviour, hydrostatic pressure, soil conditions and structural characteristics, then develop detailed specifications aligned to BS8102.

Type A is barrier protection using tanking systems to prevent water penetration. Type B relies on integral waterproofing within the concrete itself. Type C uses cavity drainage systems to manage water that penetrates the structure. Each has appropriate applications depending on ground conditions, building use and risk tolerance. We assess which type—or combination—suits your project based on site-specific factors and requirements.

No. We're independent consultants with no commercial ties to manufacturers or installers. This means our specifications are based purely on technical suitability, performance requirements and site conditions. We evaluate systems objectively and recommend solutions that best protect your structure, regardless of brand.

BS8102 is the British Standard for protection of below-ground structures against water and ground contaminants. Compliance ensures your structure meets regulatory expectations and industry best practice. Our designs reference BS8102 throughout, providing evidence-based specifications that satisfy building control and professional standards.

Yes. We design retrofit waterproofing solutions for buildings with failed or inadequate protection. Retrofit designs may use cavity drainage systems, tanking applied to internal faces or injection techniques—selected based on access, disruption tolerance and performance targets.
