CSA S is a design standard for parking structures. The height of the curb should be at least the depth of the overburden plus minimum grade terminations, as specified in CMHC guidelines.

Continuity of the waterproofing systems must be maintained. Each building will have unique circumstances. The podium slab is protected with a hot-applied waterproofing system, then concealed with compacted granular and a concrete topping not shown, for clarity. It has been reproduced with permission. The heart of the standard is Table 1, which sets out acceptable minimum protection systems based on the requirement for protection against corrosion and leakage.

Hot-applied waterproofing was installed on the podium deck slab and terminated flush with the surface of the asphalt pavement removed in this photo. However, most membranes are not UV-stable and cannot be left exposed to environmental conditions. It is up to the building designer to verify the adequacy, practicality and implementation of their transition details. There are many waterproofing systems available to designers.

Canadian Standards Association issues tougher rules for parking garages

Figure 5 is a sample detail for a brick masonry termination to a podium deck slab. Notes to tables and figures are considered part of the table or figure and may be written as requirements. As the voice of the U. The exposed bricks were found to be badly csq and spalled at some locations.

Perhaps not coincidentally, many rubberized asphalt waterproofing systems are compatible with moisture barriers found in cladding systems.

The curb extends approximately mm above the concrete topping and protects the continuity of the waterproofing membrane behind it. Designing waterproofing transitions between these categories requires a unique level of knowledge, experience and understanding.


CMHC best practice guide for flashing, detail 2. Comment on draft standards. The details published by the CMHC provide designers with a guide for various cladding transitions such as windows and roofs, and junctions between cladding systems such as EIFS to brick masonry. In general, cladding systems should never finish below-grade and there should never be void spaces between the cladding system and the podium deck waterproofing system. There is a vast array of cladding systems which can be installed in multiple configurations.

This was likely caused by moisture entrapment in the bricks.

The challenge for the designer is to develop a continuous waterproofing system that is effective. This includes pedestrian traffic areas adjoining to or contained within parking structures.

The original standard, published inwas the first one written specifically for the construction of parking structures. We have no amendments or corrections for this standard. At the de-gree turn, where the waterproofing would normally be exposed to weather elements and direct sunlight, the water-proofing system is protected by rigid insulation or metal flashing.

In other cases, cladding systems need to be locally modified or replaced due to poor base building design.

Standards Council of Canada

Government December 31, That spares the concrete from cracking and de-lamination, but hides the corrosion of the coated rebar. Waterproofing systems can be comprised of the membrane, sheathing, reinforcement, protection board and other components.

Learning resources Learn more about standardization and the Standards Council of Canada. Over the course of many podium restoration projects, we have exposed poorly designed transition details. In situations where the building cladding and podium deck waterproofing systems are designed by different parties, there is an additional challenge to ensure design coordination.

It is the intention of this article to identify the challenge in designing effective cladding to podium deck transitions and I hope that designers will consider this issue more carefully in future developments.


The CMHC guideline for brick masonry does, however, provide some relief.

However, in each of the CMHC guidelines, the cladding terminations at grade do not take into account below-grade structures, such as podium decks. Skip to main content Skip to footer. Byhowever, evidence showed that some concrete parking decks reinforced with FBECR were experiencing severe cracking. CMHC best practice guide for curtain walls, detail 17, http: A similar detail should be prepared for cladding to podium deck transition.

The designer needs to take into account podium deck finishes asphalt pavement, granular overburden, landscaping, etc. The cracks were typically wider than those formed by drying shrinkage within concrete reinforced with traditional steel. Recent Comments comments for this post are closed.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of parkimg note accompanying a clause is to separate from the text explanatory or informative material. Waterproofing systems are only effective when they are continuous, regardless of whether they are buried within the cladding assembly or multiply protection systems applied on structural slabs. InfrastructureProjects December 31, Paking Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

As previously discussed, improperly detailed cladding to podium deck transitions can result in premature cladding failures, water and 4s13 infiltration and premature podium waterproofing failures. The study concluded that the poor performance of parking structures was a result of design and construction practices that fell short of those required to withstand the harsh Canadian environment.

The CMHC also provides termination transition recommendations at grade, such as: This standard is not included in any packages.
