A leading consultant in concrete technology, DBA Engineering Ltd offers services ranging from evaluation of deterioration and damage to buildings, parking structures, highways, airfields, bridges, marine works, dams and tunnels to complete material controls and quality assurance on new constructions projects.

Our expertise includes design, specification, application and control of approved special cement systems needed during accelerated construction programs.  Safe concrete-stripping strength requirements must be met through advanced curing processes and in varying temperatures.

We provide field and laboratory testing for all types of construction, our lab is certified in all aspects of concrete and aggregate testing (CSA-category II).
