Pull-Off Adhesion Strength of Bonding Layer on Concrete .

Our Services

Evaluating the Bond Strength of bonding layer placed on concrete by pull-off adhesion strength test.

Pull-Off Adhesion Strength of Bonding Layer on Concrete is a crucial evaluation to determine how well a repair mortar, overlay, or coating adheres to the existing concrete surface. This test measures the tensile stress required to cause separation at the interface, providing a direct assessment of the adhesion quality, compatibility, and long-term performance of repair systems. At Global Lab, we conduct pull off adhesion strength Testing as per ASTM C1583 standard using precision pull-off adhesion testers. Our NABL-accredited testing ensures accurate data on pull off adhesion strength, helping engineers, contractors, and material manufacturers validate the reliability of repair and overlay systems under actual service conditions.

Why Strength of Bonding Layer on ConcreteMatters.

Ensures Durability of bonding layer on concrete for Repair & Overlay Systems

A strong bond ensures that the repair or overlay material remains securely attached to the existing concrete, under mechanical stress.

Verifies Surface Preparation Quality

Proper surface preparation — including cleaning, roughening, and removal of laitance — is critical to achieving durable adhesion. The test confirms whether the preparation methods used were effective.

Assesses Compatibility of Materials

Different repair mortars or polymer-modified systems have varying thermal and mechanical properties. Bond testing ensures compatibility between the substrate and the overlay, reducing the risk of delamination or debonding over time.

Prevents Costly Failures & Ensures Long-Lasting Repairs

The test provides on-site verification for repair projects and performance validation for manufacturers developing new materials or coatings.
