Latest Techniques for Repair & Rehabilitation- A Perspective

Epoxy Crack Injection

For a successful repairing work of a structure, the most vital things to be considered are identification of the root cause, selection of the right products & methods, proper repairing of the damage by skilled applicators, and last but not the least, assurance that the repaired structure is protected from further deterioration, say experts.

Latest Techniques for Repair Rehabilitation
Concrete is the most versatile construction material with several advantages over other construction materials. However, very often we notice some distress/damage in concrete in the form of cracks, spalling of concrete, exposure of reinforcement, excessive deflections or other signs of distress which call for either repairs of the affected areas or strengthening of the entire structure.

Before we start the repairing, it is important to identify the root cause of the deterioration. A faulty diagnosis may lead to improper selection of materials and repair techniques, leading to the failure of the repaired zone again. If the cause is properly identified, successful repairing can improve the strength and durability of the structure, thus extending its life.

Once the cause has been identified, repairing technique should be selected. The method to be adopted for repair or restoration of the structure depends on the cause, extent and nature of damage, function and importance of the structure, availability of suitable materials, and a thorough knowledge of the long-term behavior of the materials used for the repair work. A variety of new materials and efficient solutions such as high strength pre-packed mortars, ready to spray mortars, micro-concrete, concrete & corrosion protection system, different kind of sealants, coatings etc, have been developed for the repair and restoration of damaged structures. Depending upon the requirement, the repairing technique may be of a superficial nature or may involve replacement of the affected part(s).

Apart from identification of cause and selection of right material & method, proper application of material is a vital aspect in R&R activities, hence, applicator training is of utmost importance. As materials get more sophisticated, the application techniques and applicator skills need to be improved simultaneously for the execution of durable and sustainable projects.

Here, we're presenting the views of captains of the industry on the current trends and innovative products & methods being adopted for successful repair and rehabilitation of structures.
