Mitigate waterproofing risks early in the Pre-Contract Service Agreement (PCSA) to ensure a solid foundation before construction begins.
Specialist waterproofing advice is often overlooked in early design stages — even on complex basement projects — leading to design weaknesses and long-term risks for Main Contractors.
Our independent, expert-led Pre-Contract Service Agreement (PCSA) Waterproofing Consultancy leads to more reliable waterproofing and more efficient procurement.

What is the PCSA Waterproofing Consultancy Process – and how does it add value?
Site and Ground Conditions Review:
We analyse all available site data—including flood risk assessments and ground investigation reports—to identify potential geotechnical or environmental issues that could impact the waterproofing strategy. We also flag any gaps in the investigation informationWaterproofing Design and Performance Evaluation:
We review the proposed design to ensure the correct waterproofing approach and performance grades are defined, understood by all parties, and aligned with site conditions. We assess compatibility between structural and waterproofing designs and evaluate how key challenges like water tables or contamination are addressed.Risk Identification:
Our team identifies any risk factors or gaps in the waterproofing design, including areas where further design development is needed. We pinpoint weaknesses or omissions in the waterproofing design—such as build-up inadequacies, drainage concerns, or inconsistencies in approach—that may require further development.Reporting and Recommendations:
After conducting our review, we produce a comprehensive report that outlines potential risks, areas of concern, and recommendations to reduce or eliminate those risks. This enables collaborative resolution among the project team.Procurement Advice:
We assess specifications and contracts and work with the project team to set competency standards. Packaging waterproofing well for tender is enormously valuable! This might include review of contractor proposals, comparison of specialist waterproofing contractor tender responses, reconsidering certain materials or approaches to ensure the waterproofing system is fit for purpose and reduces long-term risk.
