Percolation Tests provides BRE365 soakaway percolation testing and foul infiltration testing across Gloucestershire, from the Cotswolds to the Severn Vale, supporting planning applications and self-build drainage design.
Ground conditions in Gloucestershire
Gloucestershire spans two very different geological zones. The Cotswold escarpment is largely limestone-based and often percolates well, sometimes very well — occasionally too well for a standard soakaway design without careful sizing. In contrast, the Severn Vale and areas around Gloucester and Tewkesbury sit on heavier alluvial clay, which typically drains far more slowly and is prone to a higher water table, particularly near the river. This makes Gloucestershire a county where a percolation test result can vary dramatically depending on exactly which side of the county your site falls.
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 for planning submissions
Coverage across Gloucestershire
We test across Gloucester, Cheltenham, Stroud, Cirencester, Tewkesbury, and throughout the Cotswolds and Forest of Dean. Available Monday to Friday.
Why get a percolation test
Given the sharp contrast between Cotswold limestone and Severn Vale clay, an accurate site-specific test is essential in Gloucestershire — assuming a “typical” result for the area is one of the most common ways self-builders end up with an undersized or unsuitable soakaway.
