Trusted by Our Clients

We deliver major commercial and residential projects across the UK and are proud to have worked on many prestigious contracts. Some of our clients include:

How We Test

Our primary testing method is through Electronic Leak Detection, of which there are two methods:

  • LOW VOLTAGE TESTING: The wet test method, also known as earth leak detection and low voltage testing.

  • PINHOLE TESTING: The dry test method- this test is non-destructive and highly accurate, being able to detect pinholes in the membrane barely visible to the naked eye.

These tests do rely on the electrically conductive properties of the deck and insulating properties of the waterproofing to be effective so we also offer our differential pressure test when necessary such as for non-conductive decks.

Client Testimonials

I’ve worked with Thornton’s team for nigh on 10 years and I’m yet to be disappointed by any aspect of their business or interaction with any of their staff. I feel that the collaborative approach we have when working together not only benefits our site in a speedy response and solution, but it also strengthens our relationship with our onsite client team, building in faith that together we can self-solve most, if not all issues. Working with Wendy and the onsite teams is nothing short of a pleasure. I would highly recommend using Thornton Consulting Group for all investigative services when it comes to finding leak issues.

I also wanted to write to express how impressed we are with the professionalism of both Sam and Dave and there health and safety whilst on site. I will be recommending Thornton Consulting going forward to the Hospital and will certainly use this service in the future with Carillion. Many thanks, and also for attending at such short notice.

We have worked with Thornton’s for several years now and we could not be happier with the service. The team are really helpful, accommodating and always happy to help us out if we are under pressure from a client. The team are always happy to take a call to discuss a project with them to get a clear understanding of the issues found on site. Thorntons always find the issues and provide a very thorough report to outline them with recommendations on repairs required.
