Direct Tensile Proof-Load Testing on Slab Anchor
Technician in full PPE operating manual hydraulic pump and calibrated pressure gauge directly over hollow-piston pull-out cylinder mounted on anchor bolt to verify characteristic holding resistance.
In-situ tensile proof load and ultimate capacity testing on installed chemical anchors, mechanical expansion bolts, rebar dowels, and structural fixings in concrete — essential for façade, cladding, steel baseplates, and structural acceptance testing across Singapore.
The Anchor Pull Out Test applies a direct axial tensile load to installed anchors (chemical resin anchors, mechanical expansion bolts, rebar dowels, and cast-in fixings) to verify they achieve the specified characteristic design resistance in concrete.
Calibrated hydraulic tester applies tensile force → reaction bridge transfers load → inline load cell & digital transducer record verified capacity.
Anchor holding capacity is not determined by the steel fixing alone. Workmanship, hole preparation, and substrate conditions cannot be verified by visual inspection.
"A correctly specified anchor can still fail if the hole is dusty, embedment is shallow, or chemical resin is improperly mixed."
Comprehensive on-site tensile load testing across all common post-installed anchors and structural fixings in Singapore.
Bond strength verification between reinforcing steel and concrete for structural extensions and retrofits.
Verification of epoxy, vinyl ester, and hybrid chemical resin anchors under direct axial proof load.
Performance testing of expansion anchors, sleeve anchors, wedge anchors, and heavy baseplate fixings.
Direct tensile verification for curtain wall brackets, perimeter parapet fixings, and surface adhesion bond strength.
Verification of anchors supporting curtain walls, aluminium composite panels, and subframes.
Holding capacity verification for heavy mechanical risers, cable trays, and ductwork.
Verification of rooftop anchor fixings against wind uplift and dynamic equipment vibration.
Post-pour verification of accessible cast-in anchor channels, insert sockets, and lifting loops.
Field testing is conducted using compact, calibrated hydraulic testing apparatus mobilised directly to your site with traceable calibration records.
Integrated instrumentation: pressure source → hollow ram → inline load cell → anchor coupler → real-time digital force data logging.
Provides steady, controlled fluid pressure without dynamic shock loads.
Applies pure axial tension while safely distributing reaction into concrete.
Transducer calibrated with national standards traceability for precise measurement.
Interchangeable threaded couplers, button adapters, and rebar jaws for M6–M36 fixings.
Captures real-time load, peak hold, and displacement curves for consultant QA/QC.
A structured 5-stage on-site engineering roadmap executed in strict accordance with ASTM E488 and SS EN 1992-4 standards.
Review construction drawings, anchor specifications, concrete grade, and PE proof load criteria (typically 1.2 to 1.5 times characteristic design load).
Attach precision high-tensile threaded couplings or hardened rebar wedge jaws directly to the test anchor without eccentricity or bending stress.
Position rigid reaction bridge with adequate clearance spacing from the anchor per ASTM E488 to prevent confining the concrete breakout cone.
Apply tensile force steadily in calibrated increments, sustain specified proof load for 60 to 120 seconds, and continuously log load vs displacement.
Record peak load, measured displacement, and pass/fail criteria. Issue formal SAC-SINGLAS accredited engineering test report within 24 to 48 hours.

The Anchor Pull Out Test applies a controlled tensile load to installed anchors (chemical anchors, mechanical expansion bolts, rebar dowels) using a calibrated hydraulic tester and reaction frame to measure actual load capacity and displacement in concrete.
Tests are carried out per ASTM E488/E488M, SS EN 1992-4 (Eurocode 2), BS 5080-1, and ISO/IEC 17025:2017 under SAC-SINGLAS accreditation.
Please share: (1) Anchor or rebar type and diameter, (2) Substrate material, (3) Required proof test load (kN), (4) Number of test points, and (5) Site location in Singapore.
