OBC 2024 Flooring and Plumbing Standards | empcontracting.ca Inc. London Ontario
Sarah's Expert Insight
OBC Compliance Specialist
"At empcontracting.ca Inc. your construction contractor in London, Ontario, we find that proper adhesive selection for resilient flooring is often overlooked in basement renovations, leading to premature failure due to concrete alkalinity. Whether we are working on a custom lakeside home in Muskoka or a modern build in Oakville, ensuring subfloor edge support for ceramic tiles and meeting the 1.3 kN load requirement for grab bars are non-negotiable safety standards that define our high-quality craftsmanship."
9.30.5 Resilient Flooring Requirements
According to the Ontario Building Code, resilient flooring applied to concrete slabs supported on the ground must be composed of specific durable materials. These include asphalt, rubber, unbacked vinyl, or vinyl with inorganic backing. To ensure longevity and moisture resistance, these materials must be secured with a waterproof and alkali-resistant adhesive.
9.30.6 Ceramic Tile Installation
Substrate and Support
Ceramic tiles must be installed over a mortar bed or a smooth, sound base using suitable adhesives. When using panel-type subfloors, it is mandatory that all edges are supported in accordance with Article 9.23.15.3 to prevent tile cracking and structural failure.
9.31 Plumbing Facilities and Systems
Scope and Application
Section 9.31 applies specifically to plumbing systems within dwelling units. For commercial or non-residential occupancies, contractors must adhere to Subsection 3.7.2, which covers grab bars, floor drains, and barrier-free plumbing requirements.
General Construction and Safety
All plumbing construction and alterations must comply with Part 7 of the OBC. Key safety measures include protecting metal pipes from corrosion when in contact with cinders and ensuring that all installed grab bars can resist a load of at least 1.3 kN (kiloNewtons) applied in any direction.
