1.1 Inclusions

This Standard specifies requirements for precast segmental concrete paving units, manufactured from hydraulic and non-hydraulic cement concrete to be used in the construction of pedestrian and vehicular pavement and roof coverings. Segmental concrete paving units consist of either a single concrete throughout or two layers consisting of a backing concrete with a face that has a minimum thickness, commonly of 4 mm. This Standard includes units with architectural finishes or tactile surfaces.

Notes:

Annex A contains information on efflorescence and recommends methods for its removal.

The terms “paver”, “concrete paver”, “interlocking concrete paver”, “plank”, “slab”, and “concrete paving slab” are used exclusively in Clause 3 to facilitate industry classification of precast segmental concrete paving units.  To maintain clarity, these terms are not used in the subsequent sections of this Standard.

1.2 Terminology

In this Standard, “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 (non-mandatory) to define their application.

Draft Amendment to C22.1

1      Scope

1.1     General

This Guideline covers measures to reduce the risks of basement flooding, and to mitigate the adverse effects on property, public safety, and public health in case of a flood event. It covers existing, new, rebuilt, and renovated houses in rural and urban settings.

1.2 Buildings covered

This Guideline covers all types of ground-related houses, with or without basements, that are considered Part 9 buildings according to the National Building Code (NBC) including

a) detached houses;

b) semi-detached houses; and

c) row houses.

Recommendations made in this Guideline are generally appropriate for houses serviced by gravity-based storm, sanitary, combined, or third pipe systems.

1.3 Types of flood hazards[JL1] [CC2] [CC3] 

The types of flood hazards addressed by the measures described in this Guideline are

a) overland flooding associated with precipitation events  and resulting in the accumulation/ponding of rainwater and/or snow melt in and around ground-related houses;

b) storm and sanitary sewer backwater (surcharge);

c) infiltration flooding (groundwater seepage);

d) plumbing and drainage failures, including failure of sump systems and sewer lateral failure; and

e) flooding associated with improper installation of basement flood risk-reduction technologies (see Annex A).

Note: Users of this Guideline are reminded that any of the provisions outlined herein are subject to existing codes and standards that are applicable in the jurisdiction under which the Guideline user is operating. It is strongly recommended that appropriate licensed professionals conduct any work outlined in this Guideline. All appropriate local, provincial, and national codes and standards must be adhered to in the application of the provisions outlined herein. All appropriate permits and inspections from authorities having jurisdiction must be obtained when undertaking any of the work outlined here.

1.4 Exclusions

While the measures presented in this Guideline might limit some types of flood risks to a degree, this Guideline is not meant to address riverine and coastal flood (inclusive of large water bodies) risks.
