The clay-rich soils throughout the Wolverhampton area significantly impact drainage performance, especially during the region's increasingly wet winters. Clay expansion puts pressure on underground pipes, while the soil's poor drainage characteristics can lead to surface water overwhelming combined sewer systems. Our recent work across WV1, WV2, and WV3 has shown how ground movement affects older pipe joints and connections. We use this geological knowledge to recommend appropriate repair methods and preventive measures for properties across the West Midlands.
