Durabilities. Strength Testing. Mix Designs.
The smallest quantity of impurities in concrete can seriously diminish the strength and longevity of concrete works.
Our accredited laboratories and mobile facilities are equipped to perform the following concrete testing services according to testing standards set by ASTM, SANAS, BSI and more.
Design, batch and prepare freshly mixed concrete in the laboratory where accurate control of the materials and test conditions is possible.
Preparing concrete specimens from freshly mixed concrete for future testing to determine compressive strength.
A method for determining the uniformity and consistency of freshly mixed concrete from a supplier.
The use of a concrete cube press is to determine compressive strength of a sample taken from the freshly mixed concrete used in a structure.
The use of a concrete beam press to determine the flexural strength of concrete.
A method of drilling cores from hardened concrete and preparing them for testing to determine their compressive strengths.
A series of tests for product acceptance: shape, appearance, texture and color, dimensions, tensile splitting, abrasion resistance and water absorption.
A series of tests for product acceptance: shape, appearance, texture and color, dimensions, warpage, compressive strength, efflorescence, soundness, water absorptions, water soluble salts and moisture expansion.
A test to determine oxygen permeability, water absorptivity and chloride conductivity.
Determining the reinforcing depth in an existing concrete structure with the use of a rebar detector.
A Schmidt hammer, also known as a Swiss hammer or a Rebound hammer or Concrete hammer test, is a device to measure the elastic properties or strength of concrete or rock, mainly surface hardness and penetration resistance.
By extracting a core sample and treating it with a phenolphthalein solution we can determine the actual carbonation depth on a structure.
Non-destructive testing of concrete structures using stepped frequency continuous-wave ground penetrating radar to an effective depth exceeding 700mm.
A test to investigate crack width on concrete structures such as walls, tunnels and bridges with photographic recording.
Pulses of ultrasonic waves are transmitted into concrete structures to determine the uniformity of concrete, estimate the depth of surface voids and check on the effectiveness of crack repairs, the severity of damage and deterioration of concrete.
