They are likely to appoint a structural surveyor to monitor the situation before any work is deemed necessary. This monitoring may take some time, but it is always worth waiting for the correct diagnosis.

If structural repairs are eventually necessary, the good news is that they can now be carried out with much less disruption than in the past. Not all buildings are the same and therefore no two "repair jobs are the same". Sometimes simple maintenance work is sufficient, sometimes a structural repair is necessary. What we want to do is to help you distinguish between structural repair and general repair, as the two terms are not really interchangeable.

Repair methods should be designed with the expected or desired remaining service life of the structure in mind. A distinction must be made between repairs that aim to stop deterioration completely and those that only aim to slow down the deterioration processes for a limited period of time. During the course the relevant repair methods for damaged concrete structures are discussed, focusing on design methods, application principles and limitations. The scope of relevant repair methods includes the application of penetrating corrosion inhibitors and surface coatings, temporary electrochemical techniques, cathodic protection systems, bonded coatings (patch repairs) and crack injection.

As an introduction (on the first day), the course also covers deterioration mechanisms, condition assessment principles, non-destructive testing of concrete structures and standards for concrete repair. Development of a comprehensive procedure for the repair of concrete structures. Regular repairs and preventive actions serve to prolong the service life of a structure, resulting in economic savings and a reduction in material wastage. Courses are given on various topics, such as the repair of wood resins and the repair of hollow wall anchors.

This movement in the structure of a building is commonly known as subsidence, and again there are a number of ways in which cracks and bulges that occur in the wall as a result of ground movement can be repaired. If this cause is correctly identified, successful repairs can be made to improve strength and durability, thus prolonging the life of the structure, and this is not difficult to achieve. Since weights play an important role in ranking the performance of repair materials, a sensitivity analysis is performed using three different methods to assign weights in order to find more reliable results. In summary, structural repair and stabilisation offers a cost-effective, low impact and environmentally friendly alternative to demolition and reconstruction, and is vital for conserving and protecting buildings in the UK.

Repair and rehabilitation methods should be designed with the expected or desired remaining life of the structure in mind. The procedure can help civil engineers to model and select appropriate repair materials according to a set of pre-defined criteria. This paper proposes a procedure coupled with the VIKOR method to obtain the best repair material for concrete structures. While the costs associated with repairing deteriorated concrete structures can be considerable, the costs associated with poorly designed or executed repairs can be even greater.

In a patch repair, the concrete cover is typically removed up to approximately 25 mm beyond the rebar (which is then cleaned of corrosion products) and a repair material is installed. These systems are very effective in dealing with a wide variety of repair, strengthening, stabilisation situations or where the structural strength of stone, concrete and brick structures needs to be improved. Property Care Association (PCA) members specialising in structural repair should be the first port of call for practical advice on structural maintenance. In very basic terms, general repair covers work such as basic patching resulting from normal wear and tear.

A distinction should be made between repairs and rehabilitation intended to stop deterioration altogether and those intended only to slow down deterioration processes for a limited period. In addition to requiring regular maintenance, many structures need extensive repair and rehabilitation.
