Integrating structural waterproofing from design to construction

Basement waterproofing should only ever be carried out by experienced professionals who hold the CSSW (Certificated Surveyor in Structural Waterproofing) qualification required by the NHBC and new build guarantee schemes. ​

Our surveyors are CSSW (Certificated Surveyor in Structural Waterproofing) and we are registered with the Property Care Association, the governing body for damp in the UK. 

​Some of the issues you are likely to face with a new build include challenges faced when the initial site is excavated. Expert advice is needed to ensure that water, which can rapidly fill the newly dug site from rainfall and laterally through the soil, is effectively managed away from the build structure.​

Damptec will help you to ensure that your design and subsequent construction works meet the regulatory requirements for basement waterproofing.​

This would include choosing the correct waterproofing system for your new build and helping you to navigate through potential problems regarding land drainage for example.

Why it is essential to use a surveyor with a CSSW qualification

​ Many guarantee scheme providers for new builds, including NHBC and Premier Guarantee for example, will only guarantee works which have been designed by surveyors holding the CSSW qualification.  Only surveyors holding the CSSW qualification are recognised by the construction industry as having the required level of competence and specialisation to provide structural waterproofing advice. ​
