Percolation Tests carries out BRE365 soakaway percolation testing and foul infiltration testing across Coventry, supporting planning applications for extensions, new builds, and developments across the city.
Coventry sits predominantly on Mercia Mudstone, a clay-rich deposit that tends to drain slowly across much of the city, though sand and gravel river terraces along the Sherbourne and Sowe valleys can percolate noticeably better. As with many urban areas, made ground from previous development is also common and can affect results, making a site-specific test essential rather than assuming a citywide “typical” rate.
We test across Coventry city centre, Earlsdon, Tile Hill, Binley, Keresley, and the surrounding suburbs. Available Monday to Friday.
