Materials Testing Services

Successful horizontal and vertical construction is dependent on the quality of materials used during construction.  With our laboratory and field quality control operations, CEC is constantly providing consistent oversight in all aspects of construction. CEC has extensive experience in construction materials testing providing all components of field and laboratory testing including soils, concrete, asphalt, aggregates, and masonry. Along with the field and laboratory testing we can provide special inspections including but not limited to reinforcing steel, fireproofing, paint thickness, adhesion testing and structural steel. At CEC we operate to suit client needs by providing open communication and promptly delivering results. Despite the best intentions of all parties, the outcome of a construction project will always be dependent upon the materials used during construction. Thus, it is paramount that these materials are of the required quality. Layer by layer, project by project, accurate and timely test results are essential in allowing construction to be completed in a manner that stands the test of time.

Along with in house material testing services CEC utilizes reliable partners for geotechnical exploration services. From pre-design through construction our partnership with Geotechnical engineering expertise is here to provide reliable services to our clients from geotechnical recommendations to quality construction materials testing services.
