Protection as described in more detail below.Ĭhoose methods appropriate to selected repair principles in the light of available products and systems. Select appropriate principles, such as concrete restoration, structural strengthening and cathodic Consider aspects such as the likely long-term performance of protection or repair works, the acceptable number and cost of future repair cycles and the cost of future repair cycles and the costs of alternative protection or repair options, including future maintenance and access. These range from doing nothing to partial or completeĭemolition and replacement. Possible reasons for the damage, the present condition and durability of the structure, its operating en/ironment and impact on its future durability. The various steps in the process of assessment, choosing repair option, selection of product and systems, site execution and monitoring of structures described in BS EN 1504 Part 9 are illustrated below: Part 9 is the key document for the Engineer as it provides a structured approach to the selection of repair method after the cause of the cracks is determined. The challenge is to produce a range of products that satisfy the repair principles and performance. In the context of cracks in concrete, perhaps Parts 2, 3 and 5 would be more relevant in terms of material characteristics and requirements to be used. Site application of products and systems, and quality control of the works.

General principles for the use of the products and systems.Quality control and evaluation of conformity.Surface protection systems for concrete.BS EN 1504 is broken down to the following parts: Therefore, even BS EN 1504 calls for the proper assessment of defects before deciding on the appropriate materials and techniques used for the repairs. the purpose to which the repair method will address the deterioration issue, right through the quality control during the repairs and maintenance thereafter. Material requirement for various concrete repair techniques, it also covers the selection of repair methods based on principle(s) ie. Hence, it is important to have the cause diagnosed correctly.īS EN 1504 - Products and Systems for the Protection and Repair of Concrete Structures 3 4) is mainly a comprehensive set of standards for

If the assessment on why the crack has formed is incorrect, the selected method of repair may not work. An inspection and assessment is normally undertaken to determine the cause(s) of the cracks in order to determine the effective remedial strategies.
