Asbestos-containing textured surfacing materials, as well as other types of asbestos containing materials, were historically applied in significant quantities to concrete bridges and other structures built as late as the early 1990’s. During renovation (surface preparation for overcoating or total coating removal and replacement) or demolition of bridges, just like buildings, there are specific regulatory requirements such as licensure, inspections, procedures and notifications that must be followed to avoid compliance violations, litigation and to avoid unwanted asbestos exposure to employees and the environment.
Asbestos-containing textured surfacing materials, as well as other types of asbestos containing materials, were historically applied in significant quantities to concrete bridges and other structures built as late as the early 1990’s. During renovation (surface preparation for overcoating or total coating removal and replacement) or demolition of bridges, just like buildings, there are specific regulatory requirements such as licensure, inspections, procedures and notifications that must be followed to avoid compliance violations, litigation and to avoid unwanted asbestos exposure to employees and the environment.These requirements are often overlooked even by the savviest Owner.There are specific EPA, OSHA and State regulations regarding activities associated with work activities that may affect asbestos containing materials. EPA’s National Emission Standards for Hazardous Air Pollutants (NESHAP) requires an inspection for the presence of asbestos-containing materials prior to renovation and/or demolition of a facility or a facility component, and bridges are considered facilities. The NESHAP regulation, as well as some State’s regulations, require a 10-day notification prior to disturbance of facilities where asbestos containing material (ACM) is present.If ACM is present, then specific work practices are required to be implemented under the NESHAP. Further, OSHA’s asbestos regulation (29 CFR 1926.1101), contains specific requirements regarding employee training, personal protective equipment, exposure monitoring, waste packaging, medical surveillance, etc. Lastly, States may have specific requirements for managing and disposing ACM.This Paper covers the regulatory framework concerning renovations and demolitions of concrete bridges where ACM is present and an overview of traditional and novel approaches concerning the issue.
The author will present on the various generic coatings technologies available for lining concrete and discuss the advantages and disadvantages of each one. Discussion will include epoxy, polyurethane and polyurea technologies. The goal of the presentation will be to provide some guidance to the attendees on when is the right application to select each technology as part of a specification.

Inspection has always been a hot topic when it comes to coatings projects. There are some substrates that can be harder to specify due to not knowing without knowing which testing is relevant to specify and properly inspect the substrate and surface after it is coated. Concrete is probably the number one substrate that is confusing. This paper will dive into the testing that is relevant when specifying coatings for concrete tanks and structures. Whether it is how to properly check film build or whether or not an ASTM test is relevant, this paper will clear the waters and make specifying coatings for concrete tanks and structures easier.
With coating and lining of concrete, while it may seem like a simple, novel task, there are always challenges. Even though concrete may be one of the largest construction materials used today, it is a complex structural matrix that can be ever changing even in a single placement. The need for coating concrete to either waterproof, or extend the life of the structure is not new to our industry.
