River Avon alluvial ground & SuDS drainage
Pershore (WR10) lies within the lower Avon Valley, where ground conditions consist of heavy river alluvium, agricultural clay, and high water tables. Poor natural drainage in low-lying areas like Waterside, Bridge Street, and Wick mandates open-graded sub-base aggregates (MOT Type 3) wrapped in geotextile filter fabric.
This enables rainwater to drain freely through the driveway matrix into sub-surface soakaways without saturating topsoil.
