Our investigation and reporting of building defects service provides expert analysis of non-traditional properties, including Airey, Wimpey No-Fines, Cornish, Tarran, BISF and other PRC (Precast Reinforced Concrete) homes. These property types are known to experience construction-specific defects that require specialist structural and material expertise to correctly identify and assess.
We support councils, housing associations and registered providers by delivering clear, evidence-based defect reports that inform maintenance strategies, options appraisals, compliance decisions and long-term asset planning.
Why Defect Investigation Is Critical for Non-Traditional Construction
Non-traditional properties often suffer from hidden or progressive defects that are not always apparent during routine inspections. These defects can impact structural safety, durability, compliance and asset value if not properly diagnosed.
Common defects in non-traditional housing include:
- Deterioration of reinforced concrete panels or frames
- Corrosion of embedded steel reinforcement
- Cracking, spalling and loss of cover to concrete
- Movement at joints or connections
- Moisture ingress and associated material degradation
- Failure or inadequacy of historic repair systems
Our investigations focus on identifying the root cause of defects, not just the visible symptoms.
What Our Defect Investigation Service Includes
Our building defect investigations follow a structured, proportionate methodology tailored to non-traditional construction types:
Desktop Review
We review available records including original construction details, historic repairs, previous surveys and stock condition data to understand the property’s design and known vulnerabilities.
On-Site Inspection
Specialist inspections focus on structural and fabric elements most at risk in non-traditional properties, assessing defect patterns, severity and progression.
Testing and Investigation
Where required, we undertake non-destructive and intrusive investigations to assess concrete quality, reinforcement condition and durability. Testing is targeted to provide reliable evidence while minimising disruption.
Technical Analysis
Findings are assessed against the original construction system, current standards and expected performance, allowing us to determine the cause, extent and future risk of identified defects.
Clear, Actionable Defect Reporting
Our defect reports are designed to support informed decision-making, not just diagnosis. Each report clearly sets out:
- Identified defects and their underlying causes
- Assessment of structural, safety and durability risks
- Likely future deterioration if left untreated
- Recommended remedial options or further investigations
- Implications for maintenance, compliance and investment planning
Reports are written in plain English, supported by technical evidence, photographs and clear conclusions suitable for boards, asset managers, regulators and funding bodies.
Supporting Asset Management and Compliance
Defect investigation and reporting for non-traditional properties supports:
- Planned and reactive maintenance programmes
- Options appraisals for refurbishment, redevelopment or disposal
- Structural surveys and durability assessments
- PRC and NTHAS-related decision-making
- Compliance with housing quality and building safety requirements
Our reports help landlords make defensible, auditable decisions that balance safety, cost and long-term sustainability.
Why Work With Us?
We have extensive experience investigating defects in non-traditional and PRC housing, combining structural engineering expertise with practical knowledge of social housing stock. Our advice is independent, proportionate and focused on delivering clear solutions, not unnecessary complexity.
By correctly identifying defects and their causes, we help housing providers reduce risk, prioritise investment and protect residents, while extending the viable life of non-traditional properties wherever possible.
