This is the second edition of CSA S448.1, Repair of reinforced concrete in buildings and parking structures. It replaces the previous edition, published in 1993.


This Standard specifies requirements for the repair of reinforced structural concrete components of buildings and parking structures.

This Standard does not cover repairs to

(a) pre-stressed, including post-tensioned, components and structures; or

(b) non-structural slabs-on-grade.

This Standard does not cover repairs to

(a) docks and wharves;

(b) highway bridges;

(c) bins, tanks, and silos; or

(d) treatment plants.

This Standard is generally limited to materials and procedures pertaining to repairs that are accepted as industry standard and based on sound engineering practice. This Standard does not prohibit the use of innovative procedures and materials provided that

(a) such procedures are carried out by persons qualified in the specific methods applied;

(b) an acceptable level of safety and performance is provided when one of the following methods is used:

    (i) analysis based on generally established theory;

    (ii) evaluation of a full-scale structure or a prototype; or

    (iii) studies of model analogues; and
(c) such methods are acceptable to the owner.

This Standard specifies requirements for the preparation of recommendations for installation of appropriate protection materials or systems and for post-repair maintenance schedules in order to provide protection to repaired structures and components.

In CSA standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.
