About Us / Who We Are

Who We Are

Newton Waterproofing Systems is the leading independent supplier in the UK for damp proofing and structural waterproofing solutions. 

We have been involved in protecting buildings since 1848 and we are still – as then – a family run business. In 2013 the company moved to Tonbridge, Kent due to expansion of the business. We operate throughout the UK and Ireland via our Newton Specialist Basement Contractor network – and in addition we are actively developing markets in Australia and New Zealand.

“I use Newton Waterproofing Systems because of the friendly and efficient service that we get - nothing is ever too much trouble. The products are excellent and I like being part of the research and development of their products to the ongoing benefit of the waterproofing industry.
