basement sealing and waterproofing

Converting a basement, or extending a property below ground, can be a great way of increasing the living space and adding financial value to the property. It is very important to choose the right products and contractor to undertake the necessary waterproofing and sealing work for your basement. Ensure you obtain a secure guarantee and maintenance agreement from the contractor for the waterproofing system. In this way, basement sealing and waterproofing can enhance your property’s value.

How Does Basement Waterproofing Work?

We always follow the recommendations of the British Standard 8102:2022 for waterproofing below ground structures. This defines three forms of waterproofing, essential for proper basement sealing and waterproofing:

  • Type A (barrier protection) – tanking membranes applied to the inside or outside of the structure
  • Type B (integral protection) – waterbars within construction joints
  • Type C (drained protection) – a cavity drain system compromising waterproof membranes, pumps and drainage

When the consequence of failure or the risk of groundwater ingress is high, we recommend using a combination waterproofing system. We usually specify a Type C (Cavity Drain System) as one of the forms of protection. CDM Systems are maintainable, so they provide the safest approach to waterproofing a new or existing basement structure. The choice of the second system will depend on the type of structure. Our technical team will assess your project and determine the right approach. This way, you achieve the best basement sealing and waterproofing solution for your needs.

Don’t Risk Failure

We are often called in to help where the wrong basement waterproofing products have been installed or have been installed incorrectly. We can always help to put this right. However, significant delays to the project may have already occurred. Let us assist with appropriate basement sealing and waterproofing from the start.

Who Installs the Basement Waterproofing System?

We would always recommend one of our Newton Specialist Basement Contractors (NSBC) undertake the work. They are specialists in waterproofing and will guarantee both the design and installation of the waterproofing.

What Next?

Do contact one of our technical team for any further advice on your project. In addition, if you are a homeowner, we can liaise with your architect directly. As a result, we can help design the most suitable waterproofing or damp proofing solution for your property. Moreover, we can then also provide you with a list of Newton Specialist Basement Contractors in your area. Ultimately, these contractors not only hold the CSSW Certificated Surveyor in Structural Waterproofing, but also offer insured-backed guarantees for the project. Therefore, you will have complete confidence that your waterproofing is compliant, robust and professionally supported.

For architects and developers, we can attend design meetings and site visits. We provide the necessary training to ensure success with your waterproofing project from the pre-design stage to installation. This ensures all aspects of basement sealing and waterproofing are thoroughly addressed.
