On-Site Anchor Bolt Pull Testing & Scaffold Tie Verification

Statutory Scaffold Inspections Ltd provides independent, third-party anchor bolt pull testing and scaffold tie verification across Somerset, Bristol, Wiltshire, Devon, and South Wales. Using calibrated Hydrajaws digital tension equipment, we ensure your scaffold ties meet exact manufacturer loads, TG20 requirements, and NASC TG4 standards before site handover or ongoing exposure.

Why Scaffold Anchor Pull Testing Is Essential

Scaffold ties are critical structural components holding temporary works against wind lift and lateral loads. Visual inspections alone cannot guarantee that an anchor bolt has expanded correctly or secured properly into base materials like concrete, brick, or stone.

Independent pull testing verifies:

​

• Structural Holding Capacity: Verifies that fixings support specified tensile loads without slippage or masonry failure.

• Base Material Suitability: Identifies weak substrates, crumbling mortar, or hollow masonry before loading.

• TG4 & Regulatory Compliance: Fulfills your legal duties under the Work at Height Regulations 2005 and BS EN 12811-1.

• Unbiased Compliance: As an independent inspection specialist with no ties to scaffolding contractors, our reports offer true 3rd-party accountability for site managers and principal contractors.

Our Testing Process & Industry Standards

We follow strict operational protocols outlined in NASC Guidance Note TG4 (Anchors for Temporary Works).

StepTesting ActivityDetail & Compliance

​

1. Site SetupBaseline Anchor SelectionSelecting required proof-testing frequencies (minimum 1 in 16 ties, or 5 per site) across varied elevations.

​

2. Load ApplicationHydrajaws Pull TestingApplying controlled tensile loads using calibrated Hydrajaws testers up to 1.5x design load capacity.

​

3. VerificationSubstrate Integrity CheckMonitoring for anchor displacement, thread failure, or surrounding masonry movement.

​

4. ReportingDigital PDF TurnaroundLogging exact tensile readings (kN) alongside site photos and issuing digital compliance certificates on the day.
