Concrete & Brick Testing Services

UMLAB Sarawak carries out physical and mechanical testing of structural concrete and masonry from our Kuching HQ, covering everything from cube compressive strength to non-destructive in-situ checks, for building and infrastructure projects across Sarawak.

What We Test

01 / 10

Compressive Strength Test

Crushes concrete cubes or cylinders under a hydraulic press to determine the compressive strength against the design grade.

02 / 10

Density Test

Measures the density of a hardened concrete or brick sample to check it falls within the expected range for its mix design.

03 / 10

Mix Composition Test

Analyses a concrete sample to verify its cement, aggregate, and water content match the specified mix design.

04 / 10

Rebound Hammer

A non-destructive spring-loaded plunger test that estimates in-situ concrete strength from the rebound distance of the hammer. See our concrete strength testing guide.

05 / 10

Concrete Core Sampling

Extracts a cylindrical core from hardened concrete for strength testing where cast cube samples aren't available or are in dispute.

06 / 10

Water Absorption

Measures how much water a hardened concrete or brick sample absorbs, an indicator of porosity and durability.

07 / 10

Unconfined Compressive (UCS)

Tests an unconfined cylindrical sample to failure under axial load, commonly used for stabilised soil and weak rock as well as concrete.

08 / 10

Indirect Tensile (ITS)

Loads a cylindrical sample along its diameter to estimate tensile strength, since concrete and asphalt are difficult to test in direct tension.

09 / 10

Pull Off Test

Bonds a steel dolly to a concrete or coating surface and pulls it off to measure surface bond/tensile strength in-situ. See our pull-off test guide.

10 / 10

Ultrasonic Pulse Velocity

Passes an ultrasonic pulse through concrete to assess its uniformity, detect voids or cracking, and estimate quality non-destructively. See our UPV testing guide.

Standards & Reporting

Testing follows Malaysian JKR specifications and standard geotechnical test methods. Final test reports are endorsed by a Professional Engineer (PEPC).
