Golder Associates provides aggregate and materials testing at our own laboratories. The laboratories are equipped for the testing of most construction materials including asphalt, concrete, aggregate, soil, masonry and other related construction materials.

The materials testing of bituminous materials is performed to applicable requirements and guidelines. Golder ensures that correct procedures and competent engineers and technicians perform the tests and analyses.

Golder, through our subsidiary Golder Construction Services, Inc. (GCS), provides specialized services in environmental construction, including construction management and third-party monitoring of the construction of soil and flexible membrane liner systems and closure covers for solid and hazardous waste landfills, slurry walls, treatment cells, leachate collection and removal systems, and impoundments.  GCS operates a geosynthetic materials testing laboratory, offering services for physical and mechanical testing of geo membranes, geonets, geotextiles and geocomposites.
