Project Brief
Persimmon Homes acquired the former Wardley Colliery and landfill site near Gateshead to develop 144 new homes. The site, historically mined since 1855, presented complex ground conditions, including former coal seams, deep made ground, and infilled reservoirs.
Detailed site investigations highlighted variable ground conditions and a risk of settlement from former coal seams and landfill deposits. These complexities made
traditional strip foundations unviable for parts of the development. Green Piling proposed a cost-effective, engineered solution to overcome these issues.
Key Requirements
- Persimmon Homes
- 19 Plots + Garages
- Programme: 8 weeks
Results
To complement the piling system, Green Piling supplied and installed 1126m of precast ground beam. Green Piling’s innovative G-sPan system, manufactured offsite, enabled
rapid on-site installation, minimised the need for excavation, and reduced waste and disruption. It also offered resilience against weather delays, ensuring consistent programme delivery. This approach provided a faster, more sustainable solution compared to traditional methods, while significantly reducing costs and carbon impact. The combination of driven piles and precast beams delivered an efficient, risk-managed foundation solution ideally suited to the challenging ground conditions of this brownfield site.
This approach delivered significant cost and time savings, especially on the brownfield site with complex ground conditions, and provided Persimmon Homes with a fast, efficient, and sustainable foundation solution.
