Drainage-specific testing, done properly.
CS Site Investigations works directly with developers, planning consultants and drainage engineers across the UK on BRE 365 infiltration testing, percolation testing and groundwater monitoring. What sets us apart is turnaround: your results and full report land the day after testing, not weeks later (subject to terms and conditions).
We give planners, consultants and engineers data they can rely on — clear test results, sensible test locations informed by desk-study research, and reports ready to drop straight into a drainage strategy or planning submission.
(Next-day results and reporting subject to terms and conditions)
Trusted by consultants and engineers.
Quick to respond and easy to work with — testing was booked in and completed well ahead of our submission deadline.
Clear, well-presented results that we could drop straight into the drainage strategy without any back-and-forth.
Good communication throughout, and the team were flexible around access to a fairly awkward site.
