Materials testing
Our full range of independent third-party concrete and aggregate testing services can help ensure both the quality of your concrete and the quality of your aggregate. We help you meet strict regulations and quality standards, and therefore quality and compliance assure.

We offer you comprehensive concrete testing at every stage of your project. From on-site slump testing as you pour your concrete, through to testing hardened samples for physical characteristics in our laboratories, our concrete testing includes:

\

Sampling of fresh concrete and slump testing on site

\

Making and curing test specimens on your site and in our laboratory

\

Compression and flexural testing

\

Compression tests on molded specimens and on hardened concrete cores

\

Mass per unit volume testing for hardened concrete

\

Securing and testing cores from hardened concrete

\

Flexural strength and toughness of hardened concrete

\

Testing for the compressive strength per unit mass of grout

\

Water absorption and permeable voids testing

\

Apparent volume testing

We offer you broad aggregate testing at every phase of your project. From our on-site quality control monitoring when you source the aggregate, right through to physical characterization in our specialized laboratories, our services include testing for:
