The Construction Materials Group provides a level of assurance to designers and construction teams that the primary building materials meet established criteria through accepted standardized testing protocol.
RJLG’s experts work with clients to minimize material replacements, reduce the likelihood of deterioration, avoid potential failures and investigate and evaluate construction materials related problems and failures. Engineering support, trained technical personnel and a team approach have been the keys to success.

Construction materials failures range from small in scope to catastrophic. RJLG combines technologies of physical and mechanical metallurgy with fracture mechanics to determine the structure, strength and fracture properties of materials to determine how and why materials fail.
The evaluation of service failures requires investigative skill, technical knowledge and ready access to analytical instrumentation. RJLG regularly performs investigations to resolve quality claim disputes, and to develop improved product performance and reliability. Some of the most commonly solved problems include failures associated with:
- Abrasive Wear
- Corrosion
- Fatigue
- Manufacturing Errors
- Materials Selection
- Overload
- Poor Design
- Poor Fracture Toughness
