Newton CDM System InstallAfter more than 170 years in business, Newton Waterproofing Systems remain a leading independent supplier of waterproofing systems for all below-ground structures, no matter the size.

Not only does Newton supply an extensive range of products, but the company also has a team of dedicated technical staff to offer support for your project – from design right through to post-installation maintenance via our network of specialist contractors. Newton’s site support team are also on hand to undertake quality assurance visits and on-site training when required.

In the current market, it is becoming increasingly difficult for specifiers and contractors to secure Professional Indemnity cover for waterproofing designs.

We are in the phase of the market cycle where in general, insurer capacity is withdrawing from the market, competition is reducing, premium rates are increasing, policy coverage is narrowing and insurers are being highly selective about which risks they choose to insure. Insurance Market Conditions Q3 2020, Evans Mockler*

At Newton’s we are proud of our leading technical services, having maintained our Professional indemnity insurance for waterproofing design for over 20 years. We have been supporting specifiers with designs since the 1930s. We are delighted now to formally offer a bespoke waterproofing design service, backed by our insurers and our Professional Indemnity policy.

The British Standard for Waterproofing

The British Standard for Waterproofing, BS 8102:2009, recommends that a waterproofing specialist is included as an integral member of the design team. By employing Newton’s team of industry-qualified experts, you will benefit from the knowledge and expertise of one of the most experienced companies in the UK waterproofing industry.

Qualifying projects can also benefit from the Newton Latent Defects Guarantee. The guarantee is the first meaningful, insurance policy from a UK waterproofing supplier that is backed by an A-rated, UK-based insurer, and provides up to 12 years of cover for all structural waterproofing defects arising from the workmanship, design, and/or materials. All policies are assessed on a case-by-case basis by Newton’s insurer at the design stage.
