Structural reinforcement provides for increased load capacities in existing buildings and structures or their individual parts. 

The need for structural reinforcement usually occurs in cases where the load-bearing structures no longer meet the requirements for normal use due to higher loads or the appearance of unacceptable defects. 

Structural reinforcement often proves to be more economical than erecting a new building or structure. Sometimes structural reinforcements are called for because of other considerations such as necessity of preserving buildings of historical and architectural worth. 

In some cases beddings and foundations are reinforced, usually when building additions are made or service loads are increased.
