CONCRETE REPAIR & RESTORATION
The Best Process, People & Equipment For Every Project
The prime factors in concrete deterioration are air and moisture which result in carbonation of the concrete. In colder climates the use of salt, as a deicer, results in chloride attack of the reinforcing. Both carbonation and the presence of chlorides destroy the natural alkalinity of the concrete resulting in corrosion and subsequent expansion of the embedded reinforcing. A less common form of concrete deterioration is seen in the form of alkali silica reaction which results in the paste around the aggregate turning to a gell - the subsequent expansion causing cracking and spalling.
The need, and sometimes urgency, to undertake most concrete restoration projects is due more to protecting the public and property from falling hazards as opposed to any type of imminent structural failure. Strict ordinances are in place from many local authorities and governing bodies to ensure that building owners undertake inspections at predetermined intervals by a licensed professional.
The advent and continuing evolution of the concrete repair industry has produced numerous products and in turn methods of repair and application. The establishment of the International Concrete Repair Institute (ICRI), of which CSI is a sponsor Member, has redefined the industry by combining the knowledge of Engineers, Contractors and Manufacturers to establish committees which generate accepted guidelines for methods and work practices.
A variety of modified cementitious repair materials have been developed to accent the different forms of repair methods ranging from hand patching, form and pump, to shotcrete. In furthering the technology and development in this industry more focus has been attributed to preventative maintenance in the form of cathodic protection and procedures involving re alkalization and de-chlorinization.
With any concrete repair project identifying the source of the problem, developing a scope, selection of materials and method of repair are essential to the success and achieving the desired end product.. Measures must also be taken to ensure that the source of the problems are addressed and thus prevent re-occurence in the future.
CSI is one of the largest concrete repair contractors along the Eastern Seaboard, having completed multiple projects ranging from $ 10K to $9,000,000 since 1996. We are certified applicators of all the major manufacturing companies including Master Builders, Thoroc, Sonneborn, Sika, Conproco, Silpro, Cathedral products, Tamms, and Quickcrete.
