New Build Basements

New build basements

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. 

Basements are an increasingly popular option as the cost of land goes up, but it is vital that the work is carried out correctly right from the start if it is going to be signed off and a guarantee provided, paperwork which is vital when it comes to selling your property.  This is why it is so important to use a qualified waterproofing designer.

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. 

What services can Damptec Systems Ltd offer

Damptec Systems Ltd can be there at the start with you to assist and advise the design and construction teams to ensure that the design specification meets the requirements of BS8102:2009 the Code of Practice for the Protection of Below Ground Structures Against Water from the Ground.

What issues will you face with a new build?

These might 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.

Let Damptec 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.

The design stage

We can help with ensuring the integration of the right basement waterproofing system into the overall build at design stage.  Our assistance would include full specifications prior to the installation of the system and once it has been installed.

Damptec Systems Ltd consultancy service, provided by our CSSW qualified surveyor, would include:

  • Basement waterproofing consultation from the design stage onwards

  • Project management whilst works are ongoing until completion

Why it is essential to use a surveyor with a 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. 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 this qualification.

As part of our service as a basement waterproofing contractor we are able to offer insurance backed guarantees.  Service contracts are also available for the basement waterproofing element of your new build.


Steps to ensure your new basement meets the criteria for a warranty

  • Use specialist structural waterproofing companies to design and install tanking systems.


  • Ensure the design is produced by a qualified waterproofing designer, CSSW i.e. Certificated Surveyor In Structural Waterproofing


  • Qualify for a 10 year Insurance Backed Guarantee for Workmanship and materials


  • Ensure installation works carried out by fully qualified trained structural waterproofing technicians


  • Bear in mind that ALL new build basements require a combined structural waterproofing system to reduce the risk of failure.
