• The standard maintenance of concrete structure is
  essential to preserve its life and strength.
  Improper care and ignorance to small defects may
  lead to major or permanent damage to the
  structure. Various maintenance routines and
  techniques are practiced widely to avoid such
  repercussions. If in case such routines are not
  followed regularly, structure may face
  deterioration causing the owner to undertake
  frequent repairing tasks. The causes for
  occurrence of distress in a concrete structure
  may be diverse. While the design failures and use
  or poor quality material can be a major cause,
  weather can also severe negative impact resulting
  to damage. In such situations, refurbishment of
  the distressed structure should be undertaken to
  restore its strength and life.

Causes for Distressed Structures

• Identification of core issues within a structure
  requires immediate repair and rehabilitation of
  structures such that it can be carried out
  successfully, and can help undertakers achieve
  utmost results. Some of the main causes of
  failure which needs to be observed by structure
  owner have been listed below
• 1. Issues with calculated and measured designs
  of the structure.
• 2. Improper construction or use of poor quality
  material.
• 3. Poor maintenance or no maintenance causing
  fungus.
• 4. Factors such as moisture and constant
  exposure to water causing cracking of concrete or
  erosion or metal bars and plates for structures
  like bridges, dams and canals.

• 5. Earthquakes, cyclones, fires, floods and
  other such natural disasters.6. Chemical attack
  in and around places like industries and
  factories.7. Aging of the structure itself. 
• Once the correct cause, nature and extent of the
  distress are identified, a suitable technique can
  be applied to restore the structure to its former
  glory. A proper diagnosis helps to chalk out
  perfect repair implementation plan for
  refurbishment of building that too within right
  time.

Material Used for Repair

• There are several materials that can be used as
  repairing procedures. Cement is the key material
  used for repair work. Variations of cement such
  as cement concrete or cement grouts can be used
  for specific tasks by either applying a thick
  paste type mixture for construction or filling in
  large cracks or spraying cement using high
  pressure nozzles for the portions with fine
  cracks. The other material used is resin. This is
  usually used to help the structure with the
  properties such as strength, better and quicker
  adhesion, resistance to chemical attacks as well
  as repairing eroded structures.

• Techniques Used for Refurbishment While taking
  up structural repair, the requirement of
  structure needs to be studied carefully so that
  repair work yields a long term solution. The
  refurbishment may involve repairing of small or
  major part of the structure or replacing part or
  whole of the structure. The repairing techniques
  may be categorised according to the extent of the
  damage done1. Repairing cracks in walls,
  pillars, slabs, frames, etc.2. Surface
  treatment by repairing slabs or ceiling for
  issues such as cracks and seepage.
