Domestic Subsidence Assessment & Advisory Services

At Pineapple Structures, we provide specialist structural engineering expertise for domestic properties affected by subsidence, ground movement, and foundation distress. Properties built on London clay and other shrinkable soils with shallow foundations are particularly vulnerable—especially following seasonal dry spells and where mature trees or leaking drains are present.
Whether you are a homeowner concerned about recent cracking, a buyer needing clarity before completing a purchase, or a seller looking to resolve structural issues to protect your property’s value, we offer clear, pragmatic, and independent technical advice.
Our Core Services
- Homeowner Structural Appraisals
Comprehensive inspections and detailed technical reports assessing active cracking, structural distortions, or foundation movement. We identify root causes and outline proportional, step-by-step remedial action plans. - Pre-Purchase Subsidence Assessments
Focused structural investigations for prospective buyers navigating homebuyer survey findings or mortgage lender retention requirements. We provide clarity on risk, liability, and potential remediation costs. - Pre-Sale Advisory & Defect Resolution
Tailored guidance for vendors seeking to address subsidence issues, resolve buyer enquiries, or manage insurance claims prior to putting a property on the market.
Remedial Solutions & Mitigation Strategies
Every property requires a tailored strategy. We evaluate the full spectrum of engineering and environmental options to direct you toward the most practical and cost-effective approach:
- Tree & Vegetation Management
Advice on managing clay shrinkage caused by root activity, including liaising with arborists and navigating local authority tree preservation orders (TPOs) or council tree removal enquiries. - Drainage Defect Remediation
Identifying and diagnosing underground drainage leaks or washouts that exacerbate localized foundation instability. - Insurance Claim Assistance & Support
Independent expert assessment and reporting to support homeowners through the process of making formal insurance claims for structural subsidence. - Underpinning & Deep Foundation Solutions
Design and specification of traditional or piled underpinning systems where structural stabilization is required. - Root Barrier Potential
Highlighting where subsurface root barriers may offer a viable alternative strategy, particularly where tree removal is prevented by the council or underpinning is undesirable due to impact on insurance. - Low-Carbon Resin Injection Techniques
Where suitable, evaluating high-density resin injection solutions. Resin injection provides a minimally invasive, rapid, and low-carbon alternative to traditional concrete underpinning, significantly reducing site disruption and environmental impact.
