Services
Subsidence Remediation
Our subsidence remediation services address structural damage caused by tree root activity and soil movement. Using root barriers and soil rehydration techniques, we stabilise foundations for terraced houses and commercial buildings. With 14 years of specialist experience, we provide permanent solutions that prevent recurring damage.
Tree Root Barriers
Tree root barriers prevent subsidence by controlling root growth near structures. Our barriers use high-density materials installed to depths exceeding 3 metres. This technique protects properties while maintaining tree health, offering a sustainable alternative to tree removal.
Soil Rehydration
Soil rehydration reverses clay shrinkage through controlled water injection. This method restores ground volume and stabilises foundations without structural repairs. Particularly effective for severe subsidence cases, it's been successfully applied to historic buildings and modern developments.
Heave Mitigation
Heave mitigation addresses upward ground movement after tree removal. Our solutions include controlled excavation and ground reinforcement. These techniques prevent cracking and distortion in buildings affected by expansive soils, ensuring long-term structural integrity.
Insurance Solutions
We provide specialist subsidence solutions for insurance companies and local authorities. Our services include expert assessments, remediation plans, and implementation. With proven expertise in council housing schemes and commercial properties, we deliver cost-effective, permanent fixes for insurance-backed claims.
