CSA S413-94 – Parking Structures
It has been reproduced with permission. Each system is dependent on several factors, including the building cladding system in question, performance requirements, client needs and cost limitations. Comment on draft standards Influence national and international standards development by commenting on draft standards online. CMHC best practice guide for brick, detail 4. Perhaps not coincidentally, many rubberized asphalt waterproofing systems are compatible with moisture barriers found in cladding systems.
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 height of the curb should be at least the depth of the overburden plus minimum grade terminations, as specified in CMHC guidelines. That spares the concrete from cracking and de-lamination, but hides the corrosion of the coated rebar.
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. You may delete a document from your Alert Profile at any time. The challenge for the designer is to develop a continuous waterproofing system that is effective. Over the course of many podium restoration projects, we have exposed poorly designed transition details. However, in each of the CMHC guidelines, the cladding terminations at grade do not take into account below-grade structures, such as podium decks.
Alon is a graduate from McMaster University and has been working in the construction and consulting industries for almost 10 years.
Waterproofing systems can be comprised of the membrane, sheathing, reinforcement, protection board and other components. Byhowever, evidence showed that some concrete parking decks reinforced with FBECR were experiencing severe cracking. Leaders of provincial construction associations agree has been a year of gr 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.

The podium slab is protected with a hot-applied waterproofing system, then concealed with compacted granular and a concrete topping not shown, for clarity. Building envelope systems are typically divided into roofs, walls and foundations.
There was no waterproofing membrane joining the curtain wall to the concrete curb. Podium decks are typically constructed of reinforced cast-in-place or precast concrete and have provisions for protection against corrosion and water leakage. The exposed bricks were found to be badly cracked and spalled at some locations. We have no amendments or corrections for this standard.
In other cases, cladding systems need to be locally modified or replaced due to poor base building design. CMHC best practice guide for curtain walls, detail 17, http: 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.
Others December 31, This standard is not included in any packages. The curtain wall cladding system terminated approximately mm above the podium deck slab. There is currently no commercially viable and standardized method for monitoring the presence, extent and rate of this latter form of corrosion, said Jeffs. As the voice of the U. 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.
Continuity of the waterproofing systems must be maintained. The structurss also concentrated on the use of low permeability concrete and the use of corrosion inhibiting admixtures. However, most membranes are not UV-stable and cannot be left exposed to environmental conditions.
He specializes in the review, analysis and restoration of buildings, particularly parking garages, podium decks, balconies and other structural building components. There is a vast array of cladding systems which can be installed in multiple configurations. Standards Subsctiption may be the perfect solution. Immediately below the curtain wall pressure plate is a mm void space previously concealed with metal flashing but removed in this photo and a mm tall parling curb.
These include areas such as stairs, and pedestrian bridges from parking structures. The CMHC guideline for brick masonry does, however, provide some relief.
Canadian Standards Association issues tougher rules for parking garages
The cracks were typically wider than those formed by drying shrinkage within concrete reinforced with traditional steel. He cited the reduction in the number of parking structure restoration projects over the last decade as proof. 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.

InfrastructureProjects December 31, Government December 31, The edition, for example, is more conservative about applications for fusion bonded epoxy coated reinforcing FBECR steel.
