Percolation Tests provides BRE365 soakaway percolation testing and foul infiltration testing across Warwickshire for planning applications, self-builds, and small developments.
Ground conditions in Warwickshire
Warwickshire sits largely on Mercia Mudstone (formerly known as Keuper Marl), a heavy clay-rich deposit that covers much of the county and tends to drain slowly. Some areas, particularly around river terraces near the Avon and Leam valleys, have sand and gravel deposits that percolate considerably better. Because of this contrast, soakaway feasibility varies plot to plot, and it’s common in Warwickshire for a percolation test to determine that an alternative drainage strategy, rather than a standard soakaway, is the right solution.
What we test for
- BRE365 percolation testing for surface water soakaway design
- Foul effluent infiltration testing (Part H) for septic tanks and treatment plants
- Drainage strategy (SuDS) support, working with civil engineering partners
Coverage across Warwickshire
We test across Warwick, Leamington Spa, Stratford-upon-Avon, Rugby, Nuneaton, Kenilworth, Bedworth, and the surrounding rural areas. Available Monday to Friday to fit around build schedules.
Why get a percolation test
Given the prevalence of slow-draining clay across much of Warwickshire, planning authorities routinely require BRE365 test evidence before approving drainage conditions — and a test can also save you from over-specifying (or under-specifying) a soakaway that won’t perform as expected.
