Checklist for Specifying Waterproofing Solutions
Kevin Dodds, Managing Director at Delta Membrane Systems Limited, provides guidance on the essential considerations involved in designing and specifying effective waterproofing solutions.
Structural waterproofing forms a fundamental part of safeguarding the integrity of buildings and structures. The primary purpose of waterproofing is to prevent water ingress, which, if left unaddressed, may lead to significant structural damage over time. In the context of subterranean structures, designing and specifying appropriate waterproofing solutions demands careful attention to a variety of factors. These include the intended functionality of the space, assed risks of the site – ground gas / contaminants, flood risk, hydrogeology, selection of suitable system (s) and appropriate materials, evaluation of product performance, consideration of costs, and planning for future maintenance requirements.
Engaging with a Waterproofing Designer at the earliest stages of a project is a recommendation within BS 8102:2022. Early collaboration helps avoid the pitfalls of incorrect product selection, the need for costly redesigns, budget overruns, and compromises in performance. By leveraging the expertise and practical experience of specialists, specifiers can develop comprehensive and practical waterproofing strategies that are tailored to the unique demands of their project.
Best Practice and Technical Details
Adherence to established standards and authoritative guidance documents is essential for achieving a robust and integrated waterproofing design. These frameworks provide clear benchmarks and help ensure that all aspects of the waterproofing system are addressed to a high standard, through design and specialist installation.
Approach to System Selection and Implementation
The process of selecting an appropriate waterproofing protection system should be systematic, focusing on a thorough risk assessment and a careful evaluation of site-specific conditions. It is also important to ensure compliance with relevant industry standards, such as BS 8102:2022.
Best practice involves appointing a qualified design specialist at an early project stage, conducting comprehensive site investigations, and, where necessary, implementing combined waterproofing systems—especially in areas identified as high-risk or intended for habitation. It also includes engaging with specialist trained waterproofing contractors.
Manufacturer Guidance and Safety Considerations
Strict adherence to manufacturer instructions is vital for ensuring both the safety of personnel and the optimal performance and longevity of the waterproofing products. When working with chemicals, it is crucial to follow Material Safety Data Sheet (MSDS) guidelines for the mixing process in order to prevent hazardous reactions and to maintain product effectiveness.
While third-party expertise can provide valuable perspectives based on extensive experience with various products, manufacturers generally possess deeper insight into their own offerings. Manufacturers frequently collect user feedback which assists with specific product ,perform independent testing, and analyse product performance under different conditions. This knowledge enhances their understanding of practical applications and potential challenges, making their guidance essential for users seeking thorough and reliable information.
Apples from Oranges
Guidelines for products can differ substantially. Structural waterproofing recommendations are subject to variation based on multiple factors; it is critical to recognise the specific requirements and standards applicable to each product.
