In-House

Laboratories.

Leighton operates laboratories with an extensive inventory of equipment and cross-trained staff to complete many types of tests.

Leighton’s three in-house laboratories, located in the cities of Irvine, San Diego, and Temecula, are Caltrans and DSA certified, accredited by AASHTO, and staffed by Caltrans and NICET certified technicians.

Tests offered in-house range from simple pH and sieve analyses to extremely complex such as triaxial and torsional shear strength.

In-house materials testing includes asphalt concrete, structural concrete, Portland cement concrete, Class I aggregate base, and reinforcing steel.
