We most commonly work with issues such as cracking, strength, slab surface defects, and durability. However, our work varies widely in its scope, types of materials, and purposes for the investigations. We provide QA/QC services, investigate defects and failures in materials, and assess damage from extraordinary events such as fires or seismic activity. We also provide expert witness services for projects that involve litigation.
