Laboratory Testing

FDC & Associates is a Los Angeles Certified Testing laboratory, who enjoys the reputation of being one of the leading materials and soil testing laboratories in Southern California. The laboratory’s record of “Service to our Clients” and technical excellence makes it the testing laboratory of choice for many contractors, material producers, and project owners throughout Southern California. Our laboratory can perform testing of the full range of construction materials and soils. These capabilities include rock products such as aggregates and base materials, concrete, masonry materials and reinforcing steel. The soil mechanics laboratory can perform numerous testing services including, sieve analyses, optimum moisture – maximum density, consolidation, direct shear, and R-value tests. Asphalt concrete can be tested for asphalt content, aggregate gradation, and stability, as well as other qualities. We also test built-up roofing, spray-applied fireproofing, welds, bolts, and other construction related materials. All tests are performed by qualified and experienced technicians. The Laboratory Supervisor and several of our technicians have been with FDC & Associates for years. All testing is overseen and reviewed by Professional Engineers.
