John-Newton-Approved-ContractorGuaranteed Waterproofing Solutions With A Newton Specialist Basement Contractor (NSBC)

Newton Specialist Basement Waterproofing Contractors are an elite group of professional basement waterproofing contractors who work in partnership with John Newton to provide the specifier and their clients with the highest quality products, design and installation available in all aspects of domestic and commercial basement waterproofing.

The NSBC scheme was implemented in 2003 as a response to poor and worthless contractor schemes infiltrating our industry which was resulting in clients losing faith that the waterproofing contractor was able to deliver the dry basement they required. All members of the scheme adhere to very strict membership criteria and they are required to demonstrate quality workmanship resulting in a meaningful scheme where all members provide a level superior technical excellence unsurpassed within the industry.

Becoming a NSBC approved contractor

Criteria for entry into the NSBC network is strict, and members are continually measured and inspected with Newton’s Technical Managers attending many site locations to offer support and assistance wherever possible. The absolute pre-requisites for becoming an NSBC are:

  • All Surveyors must attend and pass the three day School of Waterproofing training and exam.
  • The Management, Surveyors and Technicians are to attend an initial Newton Training Day and subsequent training modules covering all aspects of structural waterproofing with our systems.
  • The NSBC member must be an affiliated member of British Structural Waterproofing Association (BSWA)or the Property Care Association (PCA) who both are also very strict on qualification for entry.
  • A Newton Technical Representative must conduct on-site training with technicians on all practical aspects of Cavity Drain Waterproofing installation. (Continual and ongoing, includes new development)
  • All NSBC contractors must be able to offer “PI” (Professional Indemnity) on waterproofing design and offer independent insured guarantees for the installation.

We are proud to be John Newton approved basement waterproofing contractors, giving you the extra re-assurrance of the quality that this offers.
