Here at Newton, we take pride in our specialist contractors’ installations. Our network of NSBCs (Newton Specialist Basement Contractors) work closely in partnership with us to provide the highest quality products, design, and installations in all aspects of basement waterproofing.

This also includes the fact that our NSBCs also carry their own Professional Indemnity (Pl) insurance, meaning that they can perform the role of the waterproofing designer as part of the project design team, and take liability for the design of the waterproofing system on your projects.

Importantly, this fulfils the requirement of the British Standard for waterproofing, BS 8102, that “a waterproofing specialist should be appointed as part of the design team so that an integrated waterproofing solution is created.”

Furthermore, Newton Specialist Contractors will further support their work by providing their own insurance-backed installation guarantee, therefore giving the specifier and client the peace of mind that their project is in safe hands.

The fact that Newton Specialist Contractors can provide these assurances is due to the strict criteria that all members of the network must adhere to. As well as carrying PI and guaranteeing their work, NSBCs must also demonstrate consistently high-quality workmanship and technical excellence, and are audited to ensure this is the case. The result is a highly effective and meaningful approved contractor scheme.

Newton highly recommends using one of our specialist contractors in any project where there is an element of below ground waterproofing.
