Cut and Pull-Out Test.

Our Services

Direct Evaluation of Bond Strength Between Reinforcement and Concrete.

The Cut and Pull-Out Test is an important semi-destructive test used to determine the bond strength between steel reinforcement and surrounding concrete. It helps assess the anchorage performance, construction quality, and in-situ concrete strength, making it a valuable diagnostic tool for both new structures and existing rehabilitation projects. At Global Lab, we conduct the Cut and Pull-Out Test using calibrated hydraulic jacks and digital load cells, ensuring high accuracy and compliance with IS 2770 (Part 1): 1967, ASTM C900, and BS 1881: Part 207 standards. Our team of structural engineers provides NABL-certified testing and interpretation for reliable assessment of material bonding and durability performance.

Why COPAMatters.

Evaluates Bond Strength Between Steel & Concrete

Ensures that the reinforcement is properly anchored and that the concrete has developed adequate bond strength to safely transfer loads.

Assesses Quality of Construction and Materials

Detects issues like poor compaction, low concrete strength, or inadequate embedment length, which can lead to premature structural failures.

Provides In-Situ Strength Data

Unlike cube tests, the pull-out method reflects actual field performance, offering a realistic measure of concrete strength and bonding conditions at specific locations.

Useful for Old & Repaired Structures

Helps assess the remaining bond capacity in corroded or deteriorated structures and validates repair and strengthening effectiveness after rehabilitation works.
