A CSSW (Certificated Surveyor in Structural Waterproofing) is a professional qualification for diagnosing and designing solutions for moisture ingress in below ground spaces. They are essentially a waterproofing design specialist who is experienced and qualified in dealing with moisture ingress in below ground structures and can provide design solutions for waterproofing systems. These are designed to British Standard 8102, the industry standard for below ground waterproofing.

In order to make sure any below ground waterproofing project is compliant with BS8102 you should always use a trained and competent CSSW qualified surveyor.

Due to the complexity of waterproofing, and the risks involved, a trained professional should be appointed at the earliest opportunity when considering a waterproofing system. The surveyor will work closely with architects or engineers to provide a system fit for the structure and environment, and can design a system with a combination of Type A, Type B and Type C methods of waterproofing.

Many properties have unused below ground spaces that can be converted into a habitable room, making them an excellent way to increase living space without moving home. They can also add significant value to your property, making it a valuable investment. Because these spaces are inherently below ground - this means they are susceptible to moisture ingress, flooding and other issues related to dampness.

In order to keep the internal space dry, elements of waterproofing are required to prevent moisture ingress. This not only includes lateral penetrating damp into the below ground space through walls and floors, but also factors such as flood risks, ground surface water runoff and high water tables.  Even in a permeable subsoil, ground water will often require time to fully drain away, and this can result in limited pressure periodically coming to bear against the structure.

All of this must be taken into account by a CSSW qualified surveyor during a waterproofing survey. They will then provide a waterproofing survey report with their findings, and recommendations for a waterproofing system designed specifically for the property involved, including any additional heating and ventilation requirements dependent on end use.

If you wish to go ahead with the waterproofing system design, our trained and experienced technicians will carry out the installation to the highest standards backed by our quality assurance checks throughout the process.

If you choose to go ahead with the installation of a basement system designed by our CSSW qualified surveyor, you are in safe hands from start to finish, giving you peace of mind.

Trained technicians local to you will install the waterproofing system to prevent moisture ingress, while using the correct products, installed as intended. This is a hugely important step as one mistake and the waterproofing could fail, leading to a system failure and moisture ingress. This is why all Peter Cox installations are backed by our quality assurance process ensuring checks are conducted throughout the installation and signed off by a lead technician.

Peter Cox are approved installers of Delta, Koster, Newton and Safeguard waterproofing products, and all of our technicians undergo rigorous in-house and onsite training in order to be able to qualify as a trusted partner. All products used undergo an extensive testing process by the manufacturers to attain BBA/BDA certification.

The CSSW qualified surveyor will visit the site throughout the installation of the system, and will be responsible for quality assurance checks throughout installation and a final sign off process in order to ensure our exceptionally high standards are met. This will give you peace of mind from start to finish.

Once the installation is complete, we will ‘sign off’ the project with a final handover.

Once complete, the basement system designed to BS8102 will receive a 10 year guarantee, giving you long term peace of mind that your investment is protected.

While DIY fixes for waterproofing may be tempting, by designing a system that is built to last you will save money by minimising repair costs and preventing further damage in the future.
