High-level ultrasonic testing and structural assessment of failing silos
Structural Repairs was tasked with delivering a comprehensive concrete condition survey at Selby Flour Mill. The project demanded a delicate balance between thorough sub-surface inspection and minimal operational disruption. Faced with failing concrete at significant heights and complex logistical hurdles, our engineering team deployed advanced ultrasonic scanning to map the exact structural health of the silos and provide a definitive, fully costed remediation strategy.
Critical Degradation & Complex Access
The situation at the mill was urgent – large pieces of concrete were spalling and falling away at a mere touch. We needed to deploy sensitive equipment to detect internal voids, delamination and insufficient concrete cover across the entire face of the silo.
The logistical obstacles were significant. The project required safely accessing the silo’s full height, managing proximity to a major road and contending with unpredictable Yorkshire weather. The ultimate challenge lay in rapidly translating our sub-surface findings into an actionable, code-compliant plan for critical structural remediation.
Ultrasonic Pulse Echo (UPE) Scanning at Height
To address these complex challenges, we deployed advanced non-destructive testing (NDT) technology – specifically the Proceq PD 8050. This is a state-of-the-art ultrasonic pulse echo device capable of identifying internal voids, water ingress and defects without damaging the structure.
The Deployment
- High-Level Access: We used a Genie 135 MEWP (Mobile Elevating Work Platform), allowing our technicians to safely reach and scan the entire concrete surface.
- Logistical Planning: We coordinated closely with Selby Council to arrange temporary road closures, ensuring total safety for both our team and the public.
- The Scan: Over two full days, a team of two expert NDT technicians systematically scanned the concrete face, operating efficiently despite the technical challenges of working at height in crosswinds of up to 15 mph.
The PD 8050’s sensitivity allowed us to identify areas of insufficient concrete cover, document water ingress damage and pinpoint zones of severe internal degradation.
