Concrete Materials and Petrography
When improvements are needed or failures occur, the answers are in the material.
Cracking that's progressing faster than expected. A slab that failed before its first winter. A construction defect claim that needs defensible analysis. A historic structure that needs restoration without compromising its original materials. When concrete or construction materials don't perform, the answers are in the material science—and getting them right matters for safety, durability, and liability.
RJ Lee Group brings decades of expertise in concrete, aggregates, and construction materials testing. From quality control and compliance to failure diagnosis and litigation support, our scientists help owners, builders, engineers, and attorneys understand exactly what's happening inside the material and what to do about it.
Collaborating for Impact
Lab Analysis Informed by Engineering Context
Through our partnership with Durability Engineers, LLC., we bring lab-tested insight directly into the design, evaluation, and rehabilitation of concrete structures. This collaboration helps clients bridge the gap between material science and structural performance.
