Brownfield & Infill Sites: Proving SuDS by Infiltration with BRE365 Testing

As flood and drainage scrutiny increases, planners want robust evidence that SuDS proposals will work—especially on tight brownfield and infill plots. Our Infiltration Testing service delivers BRE365‑compliant results that designers can trust.

We scope trial pit locations that reflect proposed hardstanding and drainage strategy, then carry out testing to determine infiltration rates and soakaway sizing. Results are reported clearly and quickly so the design team can progress layouts and civils without delay.

Where infiltration is marginal or groundwater is shallow, we’ll advise alternatives and sequence with contamination assessment to avoid creating pollutant pathways. Coordinating early with our Contaminated Land and Phase 1 Desktop Study services keeps your application coherent and defensible.

Give planners confidence and keep your programme moving with evidence‑led drainage design.
