Meeting Expectations When Specifying Concrete Rehabilitation

Meeting Expectations When Specifying Concrete Rehabilitation
Available for download

There are many approaches for rehabilitating deteriorated concrete. The options challenge applicators, estimators, and engineers when executing rehab projects. Selecting the cost-effective approach requires understanding the concrete condition, available coating systems, and level of effort to repair and coat the concrete. A well written specification balances a level of detail that conveys the specifier’s intent with opportunities for contractor innovation to provide facility owners with the best value.

There are many approaches for rehabilitating deteriorated concrete. The options challenge applicators, estimators, and engineers when executing rehab projects. Selecting the cost-effective approach requires understanding the concrete condition, available coating systems, and level of effort to repair and coat the concrete. A well written specification balances a level of detail that conveys the specifier’s intent with opportunities for contractor innovation to provide facility owners with the best value. Concrete condition is a primary consideration when developing concrete rehabilitation projects. Specifiers and applicators are sometimes asked to assess inaccessible locations before the work begins. Ultra-high solids epoxies, elastomeric polyurethanes, calcium aluminate cement, plastic membrane liners are some systems frequently proposed for the same purpose - extending concrete’s useful life. Understanding the deterioration process and repair alternatives will help estimators know what to expect during substrate prep and coating application resulting in better cost estimates and planning. This paper presents considerations for evaluating specifying and executing rehabilitation projects. Accurate assessment of concrete condition, exposure, and work constraints along with understanding the benefits and limitations of coating systems come together as part of a well written specification, providing the basis of a successful concrete rehabilitation project.

Cracks in a concrete substrate pose a challenge for coatings. Cracks that are not properly identified and addressed can lead to premature failure of the coating.  This paper will discuss the forces that cause cracking in concrete structures, as well as crack types and repair techniques.

Concrete repair is a neglected primary example of sustainable construction and green building practices. Sustainability in construction is a topic of increasing importance. Concrete has high embodied energy and much documentation exists about the sustainable nature of concrete in new construction. Concrete maintenance, protection, and repair are the ultimate acts of sustainability in construction because they preserve this embodied energy. Rating systems should be adopted to better capture the sustainable nature of concrete preservation

Basics of Corrosion in Reinforced Concrete

Concrete is the second most common man-made material after potable water, yet it is a complex material that is poorly understood. Steel reinforcement is added to improve the concrete's tensile strength and ductility and is initially protected by the high concrete pH and depth of cover concrete. Eventually, due to the ingress of deleterious ions, lowering of the pH from carbonation, or electrical potential changes within the steel, corrosion will occur.
