Rebound Hammer Testing & Rebar Scanning

In construction, verifying the strength and safety of your structures shouldn’t mean breaking them. Inch-On Materials Testing Laboratory provides professional, non-destructive evaluation (NDE) services across the Philippines. By combining Rebound Hammer Testing with High-Precision Rebar Scanning, we offer a complete picture of your concrete’s surface hardness and internal reinforcement without causing a single crack.

As a DPWH-BRS Accredited laboratory, we utilize high-precision equipment and strictly adhere to ASTM C805 and international scanning standards to ensure your structural integrity is accurately assessed.

Rebound Hammer Test (Schmidt Hammer)

The Rebound Hammer test is an essential tool for gathering rapid data on the quality of concrete elements in their actual in-place environment. It allows our team to estimate compressive strength by measuring the surface hardness of the hardened concrete.

Compressive Strength Estimation

By measuring the rebound of a spring-driven steel hammer, we provide a reliable correlation to the concrete’s strength.

Hardness Assessment (ASTM C805)

Standardized testing to evaluate the surface durability of structural members like slabs, beams, and columns.

Uniformity & Quality Control

We pinpoint low-quality zones and check for consistency across different areas of a single pour to ensure no weak spots are left hidden.

Monitoring Deterioration

Ideal for assessing surface wear in older infrastructure to determine if rehabilitation is necessary.

Precision Rebar Scanning (GPR & Electromagnetic)

Knowing what lies beneath the surface is critical before any cutting, coring, or structural retrofitting. Our rebar scanning service provides a “X-ray” view of your internal reinforcement.

Rebar Localization

Precisely map the location, depth, and orientation of reinforcing bars (rebars) to avoid accidental damage during construction.

Cover Depth Measurement

Ensure that the concrete cover is thick enough to protect steel from corrosion, meeting local building codes.

Spacing & Diameter Estimation

Verify that the reinforcement matches the original structural design and as-built plans.

Safe Coring & Drilling

Identify "clear zones" to prevent hitting post-tension cables or primary reinforcement, saving time and preventing structural compromise.

Why Combined Testing Matters

Relying on visual inspections alone can lead to hidden structural risks. For contractors, developers, and structural engineers in the Philippines, our integrated reports provide the critical data needed to:

Ensure Regulatory Compliance

Meet all DPWH and local building code requirements with certified laboratory results.

Evaluate your structure

Non-Destructive Assurance

Evaluate your structure’s integrity without the need for drilling cores or damaging finished surfaces.

Rapid on-site testing

Immediate Decision-Making

Rapid on-site testing allows for real-time feedback, reducing downtime and preventing costly structural failures.

Foundation Optimization

Early Issue Identification

Catch potential weaknesses or reinforcement errors early to ensure long-term stability for the life of the structure.
