Services

Rapid-response drainage testing.

Every service can be commissioned on its own, or combined to cover a full surface water and foul drainage strategy.

BRE 365-compliant infiltration testing

Infiltration testing to BRE 365, typically used to inform surface water drainage design where soakaways, permeable paving or other SuDS features are proposed. Test pit depths are agreed against your proposed drainage layout and local BGS/borehole records.

Percolation testing

Percolation testing carried out in line with current building regulations guidance, generally required where a foul drainage field is proposed rather than a mains connection.

Groundwater monitoring

Groundwater level monitoring, normally carried out across the winter months when levels are at their peak. Bookings for the upcoming season are best made early, as slots fill up.

Next-day results & reporting (subject to terms and conditions)

This is where we differ from most: results and a full, planning-ready report are turned around the day after testing, not weeks later — so your submission doesn't sit waiting on us (subject to terms and conditions).

Planning support

Reports written to be used directly by planning consultants and drainage engineers in support of a live application, with no extra formatting needed on your end.
