What is a concrete repair ?

Definition for the purpose of this presentation:
To restore concrete to its original purpose. Be it a column, beam or any concrete part of a structure that is “off-spec” or has been damaged or deteriorated.

A concrete repair is essentially a method of taking new material and adding it to older material by forming a multi-layer composite system which will behave like a monolithic or single block, so it can handle the required service loads and environment.

Reasons a repair is needed:

1. Physical and mechanical damage
2. Incorrect design.
3. Deterioration through use, misuse or environment. Alkali silica attack.
4. Bad workmanship
5. Steel corrosion
6. Water damage

Why Repairs Fail 
Crucial to understanding the failure before you repair

1. Incorrect diagnosis of root cause
2. Incorrect design of repair
3. Incorrect choice of the applied repair material
4. Poor Workmanship.
