Shrinkable Clay Soil Remediation in Cornwall
Manage the risks of building on shrinkable clay in Cornwall — seasonal ground movement control and foundation protection.
Shrinkable clay soils are a significant cause of subsidence across parts of Cornwall, particularly in river valleys and lowland areas. These soils expand when wet and shrink when dry, creating a cyclical movement pattern that can damage foundations and cause persistent cracking in walls.
Our clay soil remediation service combines ground investigation, moisture management, and foundation protection to control the effects of shrinkable clay on your property. We address both the immediate structural damage and the long-term management of the clay soil conditions.
Cornwall's clay soils — including the china clay deposits around St Austell and the valley clays found throughout the county — present particular challenges for property owners. Trees, seasonal rainfall patterns, and inadequate drainage all influence how much movement these soils produce.
If you're unsure whether clay remediation is the right solution for your situation, our team can help. We assess every property individually and recommend the most appropriate treatment based on the specific ground conditions, building construction, and cause of movement.

What to Expect from Our Clay Remediation Service
Every clay remediation project we undertake follows a structured process designed to deliver the best possible outcome. It begins with a thorough site assessment where we examine the damage, investigate the ground conditions, and identify the underlying cause of movement. Only once we fully understand the problem do we design the repair solution.
During the works, we maintain clear communication with you at every stage. You'll know what we're doing, why we're doing it, and what to expect next. We work efficiently to minimise disruption while never compromising on quality. After completion, you'll receive full documentation including completion certificates, monitoring data where applicable, and comprehensive guarantees.
Our clay remediation work is accepted by all major insurance companies. If you're making an insurance claim, we format our reports and documentation to meet insurer requirements, making the claims process as smooth as possible. Our insurance claim management service can handle the administrative side for you.
Why Choose Our Clay Remediation Service
Root Cause Treatment
We address the factors causing clay movement — drainage, vegetation, and soil moisture — not just the resulting damage.
Seasonal Management
Our solutions account for Cornwall's distinct seasonal rainfall patterns and the resulting cycles of clay expansion and contraction.
Tree Management Advice
Trees are the single biggest factor in clay-related subsidence. We provide expert advice on tree management, removal, and replacement.
Long-Term Monitoring
Where appropriate, we install monitoring systems to track ground movement and verify the effectiveness of remediation measures.
The Clay Remediation Process
Our five-step process applies to all our services including clay remediation. We start with a thorough assessment, carry out any necessary investigations, design a repair solution tailored to your specific situation, execute the works to the highest standard, and then make good all finishes.
Throughout the process, you'll have a single point of contact who manages everything from technical coordination to insurance liaison. This integrated approach ensures nothing falls through the gaps and the project moves forward efficiently. Many of our clients tell us that this coordinated service is one of the biggest reasons they chose to work with us.
We also work closely with structural engineers to ensure every clay remediation project is properly designed and specified. This engineering oversight provides confidence that the solution will be effective and long-lasting, and produces the documentation that insurers and future property buyers expect to see.
