Pure Basement Systems: The company to provide you with a complete waterproofing service for your projects

If you’re considering a basement waterproofing or basement conversion project at a client’s property or at your own development, Pure Basement Systems are the professional basement waterproofing contractors you can trust.

Pure have a wealth of experience of successfully completing basement waterproofing projects on new build properties, basement refurbishment schemes and on commercial properties.

Pure’s CSSW (Certificated Surveyor in Structural Waterproofing) Qualified and experienced surveyors will provide you with expert advice throughout your project to ensure your basement waterproofing system is robust and effective and will protect your property against the risk of damage from water ingress (flooding) and dampness.

Pure Basement Systems offer a comprehensive basement waterproofing system design, installation and ongoing maintenance service.

It is crucial that basement waterproofing is considered at design stage to ensure that the specified basement waterproofing system can be correctly adopted into the overall build.

There are three types of generic waterproofing system as outlined in the current British Standard BS8012 – 2009 “Code of Practice for protection of below ground structures against water from the ground”:-

  • Type A (barrier) protection – comprises of a barrier system which is applied to the structure externally, internally or within the structure with the goal of precluding water ingress/ dampness.
  • Type B (structurally integral) protection – comprises of the structure itself providing resistance to water ingress/dampness.
  • Type C (drained protection) – comprises of an integral drainage system which manages water ingress/dampness and prevents it from affecting the usable space.

Basement Contractors for all types of Properties and Projects

Basement Waterproofing Contractors select from one or a number of the above generic waterproofing systems dependent on the individual property’s risks when considering waterproofing design. The type of project, risk of water ingress/dampness and over-all buildability for the project should all be considered when selecting the appropriate waterproofing system(s).

It is not uncommon for new build projects to have a combined system of waterproofing which adopts two or three of the generic waterproofing systems.

Waterproofing Basements and safe-guarding your Project’s budget

Poorly implemented basement waterproofing can offer unpredictable and extremely costly and distressing results if not carried out by experienced, suitably qualified professionals using purpose made high quality equipment and materials.

Internal dampness and water ingress (flooding) will occur as a result of a poorly designed, inadequate waterproofing system. This will result in significant damage to your client’s property and their possessions which will be extremely costly and disruptive to remediate, it can also be pretty embarrassing and costly to your reputation too.

Pure Basement Systems trained and experienced surveyors and installation technicians will help you to remove the risk of water ingress (flooding) and dampness in your basement conversion through:

  • A thorough professional survey of your property and assessment of the risks presenting
  • Accurate, evidence based waterproofing system design and material specification
  • Professional technical installation of the waterproofing system specified
  • Planned post-installation maintenance program

What problems will a Specialist Waterproofing Company solve?

Early Consultation with a Basement Waterproofing Design Specialist is critical.

The Waterproofing Design Specialist will provide you with a specification for waterproofing of the structure and discuss other important aspects of the build/project with you.

It’s important to allocate time for installation in the program of works and important that the system can be tested after installation. Without consultation with an experienced waterproofing design specialist at an early stage vital enabling or allied components to the overall waterproofing scheme could be missed.

Speak to a Specialist at Feasibility Stage. Recruiting an experienced CCSW Surveyor and Waterproofing Design Specialist at an early stage will reduce the level of risk in terms of waterproofing at your project and help to ensure that installation time does not extend the overall site program.
