Large Basement Extension

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 basement waterproofing work however, as well as obtaining a secure guarantee and maintenance agreement from the contractor for the waterproofing system.

How Does Basement Waterproofing Work?

We always follow the recommendations of the British Standard 8102:2009 for waterproofing below ground structures. This defines three forms of 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

A combination waterproofing system is recommended where the consequence of failure or the likelihood of water ingress is high – and we would usually recommend that one of the forms of waterproofing is a Type C or Cavity Drain System (CDM). Because they are maintainable, CDM Systems are acknowledged as the safest form waterproofing a new or existing basement structures. The choice of the other system is largely dictated by the type of structure. We can help to ascertain what’s right for your project.

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 – but significant delays to the project may have already occurred. Let us help you get it right first time.

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.

“My friends and family were amazed how well the system did exactly what it was supposed to. Following the event, I have not had to claim on my insurance, I have not had to clean up or had any stress put on me, as my home was saved. I believe that due to your waterproofing I will be able to at any point sell my house and that due to the waterproofing system it will actually add value. My neighbours whom had not installed the flood protection were devastated at the amount it is going to cost them to repair the damage caused by the flooding, the stress it caused and is causing and the sheer turmoil it leaves behind”
