Our testing laboratory provides support to our consulting and field inspection services, while providing forensic and testing services to our clients worldwide. We work closely with ASTM in the development of test methods, testing guidelines, and specifications.

Stringent quality assurance and quality control procedures provide results that engineers can rely on as they consider recommendations, products, and materials to be used for construction or repair projects. Our clients include building owners, contractors, law firms, concrete producers, material manufacturers, engineering firms, government agencies, facility owners, and suppliers.

Our employees are active members in ACI, ASTM, ICRI, FRCA, ASCE and SWRI and several are current or past committee members, committee chairs, board members, and presidents of local and national chapters.

Our materials testing laboratory is audited and/or inspected by AMRL (AASHTO Materials Reference Laboratory), CCRL (Cement and Concrete Reference Laboratory), and the US Army Corps of Engineers.  Our laboratory accreditation includes: ISO 17025, AASHTO R18 and we are an approved laboratory for the US Army Corps of Engineers.  TEC Services can submit data to ICC-ES (International Code Council – Evaluation Service) for the following acceptance criteria:


Acceptance Criteria for Concrete with Synthetic Fibers
Acceptance Criteria for Precast Stone Veneer
AC198 Acceptance Criteria for Chemical Admixtures Used in Concrete
AC208 Acceptance Criteria for Steel Fibers in Concrete
Acceptance Criteria for Water-Resistive Coatings used as Weather-Resistive Barriers over Exterior Sheathing

Petrographic Services

SGS TEC Services provides petrographic analysis of aggregate, concrete and cementitious-based products and materials to aid in failure analysis investigations and quality control testing of building materials. This analytical tool can determine the following concrete, mortar and other cementitious products characteristics:

Estimation of water-cement ratio
Cause of surface defects
General quality and condition
Depth of carbonation
Identification and volumetric estimation of pozzolanic materials
Identification of deleterious materials and reactions
Alkali-silica reactivity
Chemical and physical sulfate attack
Degree of carbonation and other environmental effects
Segregation of Materials
Aggregate quality
Maximum aggregate size and gradation
Entrapped and entrained air contents
