ISO 16311-1:2014 PDF Download

ISO 16311-1:2014 is a standard that outlines the general principles for the maintenance and repair of concrete structures. It covers all types of existing concrete structures, including those made of unreinforced and reinforced concrete, prestressed concrete, and steel-concrete composites. The standard distinguishes between deterioration and short-term damage, such as cracking and scaling due to earthquakes or impact loading. Deterioration is the primary focus for maintenance activities.

The standard also introduces the concept of repair and prevention to restore the structural performance of existing concrete structures. It provides guidelines for addressing deterioration and implementing measures to extend the service life and ensure the durability of these structures.

However, ISO 16311-1:2014 does not address maintenance and repair aspects related to serviceability and aesthetics that do not directly impact the durability and service life of the structures. Examples of these aspects include cleaning drains, removing vegetation, and refreshing paint. Additionally, the standard does not cover the repair of defects during the construction of new structures.
