Laboratory Testing
Laboratory Testing
CRA offers laboratory services to certify aggregates, test various construction materials, and determine the properties of soil and rock.
Our laboratory facilities, equipped with the most modern and up-to-date equipment, complement our studies of soils and crushed aggregates, geotechnical, asphalt, concrete, metallurgy, and building science. No assignment is either too small or too large. Our many locations allow us to handle projects in an economical manner.
