Over 10 Years Serving
London Construction

Concrete Testing Solutions Limited has been working alongside the London construction industry since 2015. Based in South East London, we partner with main contractors, structural engineers and developers across the capital and the wider South East, delivering UKAS accredited testing.

We cover concrete testing, ground testing and geo-technical laboratory analysis. All work is carried out by qualified engineers using calibrated digital equipment, and results are reported the same day where possible, so your programme does not slow down waiting on paperwork.

The business was built on one simple principle: a testing partner should show up on time, do the job properly, and get out of your way. That has not changed in over a decade.
