We provide a wide range of technical services related to the preservation of all types of reinforced concrete structures and specialize in diagnostic evaluation, provide recommendations for and design repair and rehabilitation. 

CONCORR, Inc. are corrosion industry pioneers and have developed a unique mathematical model in 2005 to project future concrete damage resulting from the corrosion of reinforcement.  This model has been used on numerous projects for several Departments of Transportations and Private Clients to identity cost-effective long-term repair and rehabilitation solutions.  The model has also been used as a decisive factor in corporate litigation to determine the amount of damage that resulted due to negligence.

CONCORR, Inc. was established in 1990 to develop technologies and provide solutions for mitigating corrosion of reinforcement, both conventional and stressed, in reinforced concrete structures. 

It specializes in diagnostic evaluation, developing cost-effective strategies for extending the service life for the desired length of time, and designing the corrosion mitigation systems that can accomplish it. 

The company has successfully performed numerous research and development programs in all areas of corrosion of reinforcement in concrete for various National Agencies.  These projects have been funded by the Federal Highway Administration (FHWA) under the Strategic Highway Research Program (SHRP) and the Long-Term Pavement Program (LTPP), the US Department of Transportation under the Small Business Innovation Program (SBIR), the National Academy of Sciences under the National Cooperative Highway Research Program (NCHRP), and several others.  The experience and understanding obtained from these projects are brought to bear upon the structural preservation projects the company is involved in. 

An innovative mathematical Service Life Model was developed under one of these research projects.  The model has been used by the company since 2005 to project future damage based on the present condition of the structure and used in the development of cost-effective preservation solutions.  The results of the model have been used by several State Departments of Transportations, such as the Florida DOT, Virginia DOT, New Jersey DOT, Washington State DOT, and many private clients.  

CONCORR, Inc. designed the first full scale galvanic cathodic protection system to be installed on pre-stressed marine piles in 1990.  This groundbreaking technology has become standard practice now.  It was one of the first to incorporate both infra-red and ground penetrating radar technologies in corrosion condition evaluations.  The company developed the first automated system to acquire and process infra-red surveys to identify delaminations under the FHWA “Demonstration Project 84” in the early 1990s.  It also developed a mathematical model to estimate the distribution of current in an impressed current cathodic protection system.
