Canadian Standards Association issues tougher rules for parking garages
It is up to the building designer to verify the adequacy, practicality and implementation of their transition details. The CMHC also provides termination transition recommendations at grade, such as: Annexes are designated normative mandatory or informative non-mandatory to define their application. Please first log in with a verified email before subscribing to alerts. This standard is also available to be included in Standards Subscriptions.
Already Subscribed to this document. Subscription pricing is determined by: The curb extends approximately mm above the concrete topping and protects the continuity of the waterproofing membrane behind it.
Perhaps not coincidentally, many rubberized asphalt waterproofing systems are compatible with moisture barriers found in cladding systems.
What kind of news would you like? In other cases, cladding systems need to be locally modified or replaced due to poor base building design. Resource December 31, The cracks were typically wider than those formed by drying shrinkage within concrete reinforced with traditional steel.
Technical Documents and Brochures – Multi-level Parkings
Skip to main content Skip to footer. 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. As previously discussed, improperly detailed cladding to podium deck transitions can result in premature cladding failures, water and moisture infiltration and premature podium waterproofing failures.
The CSA has several publications specifying design requirements for concrete and steel structures. Government December 31, 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. This includes structufes traffic areas adjoining to or contained parming parking structures. The height of the curb should tsructures at least the depth of the overburden plus minimum grade terminations, as specified in CMHC guidelines.
CMHC best practice guide for curtain walls, detail 17, http: The challenge for the designer is to develop a continuous waterproofing parklng that is effective. However, in each of the CMHC guidelines, the cladding terminations at grade do not take into account below-grade structures, such as podium decks.
The designer needs to take into account podium deck finishes asphalt pavement, granular overburden, landscaping, etc. A potential solution is integrating concrete curbs to protect membranes. 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.
Others December 31, Designing waterproofing transitions between building cladding and podium deck systems requires a unique level of knowledge, experience and understanding. Learning resources Learn more about standardization and the Standards Council of Canada. The CMHC guideline for brick masonry does, however, provide some relief. Recent Comments comments for this post are closed. Designing waterproofing transitions between these categories requires a unique level of knowledge, experience and understanding.
Each building will have unique circumstances. 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. CMHC best practice guide for flashing, detail 2.
There was no waterproofing membrane joining the curtain wall to the concrete curb. Comment on draft standards. Waterproofing systems tend to be specific to these broad categories. If the document is revised or amended, you will be notified by email. 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. This standard is not included in any packages. The podium slab is protected with a hot-applied waterproofing system, then concealed with compacted granular and a concrete topping not shown, for clarity.
CSA S is a design standard for parking structures. Please first verify your email before subscribing to alerts. Your Alert Profile lists the documents that will be monitored.
Leaders of provincial construction associations agree has been a year of gr This Standard specifies special requirements for the durability aspects of the design and construction of new parking structures and parts of buildings subject to vehicular traffic.
Although this may seem trivial in the grand scheme of building design, restoration and building science consultants frequently face challenges in solving waterproofing failures and difficult-to-find leaks.
