FH 1.4: Concreate basement floor is cracked

Performance
Cracks resulting from normal shrinkage are acceptable; however, cracks in excess of 4 mm in width are not acceptable.
Warranty
One-Year - Work and Materials · Cracks resulting from normal shrinkage of materials caused by drying after construction are excluded from the statutory warranty.
Action
Cracks in excess of the acceptable condition shall be repaired.
Remarks
Generally, concrete floor slabs are not structural. Concrete floors naturally crack during curing due to shrinkage. Actual crack widths shall be determined using a wire feeler gauge* inserted inside the crack. Since the concrete floor slabs do not have to carry the load of the building, shrinkage cracks are generally considered aesthetic. Where vertical or lateral movement is evident, further investigation may be required. Where repairs are necessary, colour and/or texture will not match the surrounding concrete. See Also: 14.2 CONCRETE GARAGE FLOOR IS CRACKED. * Because it is of a manufactured, set size, an Allen Wrench/Key may be used as a wire feeler gauge.

FH 1.19: Radon Exceeds Acceptable Levels

Performance
Radon levels in a home shall not exceed 200 Becquerels per cubic metre (Bq/m3).
Warranty
One-Year – Workmanship & Materials Two-Year – Ontario Building Code Health and Safety Violations Seven-Year – Major Structural Defect • A complete list of “CONDITIONS NOT COVERED UNDER WARRANTY” is on p.15 of the Guidelines.
Action
Where long-term test results indicate that radon levels in a home exceed 200 Becquerels per cubic metre (Bq/m3) and are the result of a Building Code violation or a defect in work or materials supplied by the builder, repairs shall be made.
Remarks
Radon is an invisible, odourless and tasteless radioactive gas commonly found in soil. Differences in air pressure between the interior of the home and the surrounding soil can draw air and gases, including radon, from the soil into the home through below-grade openings such as cracks in foundation walls and floor slabs; construction joints; gaps around service pipes, support posts, floor drains, sumps; or cavities within masonry walls and hollow metal columns. According to Health Canada, long-term exposure to high levels of radon has been associated with an increased risk of developing lung cancer. When radon is trapped in enclosed spaces, it can accumulate to harmful concentration levels. Health Canada recommends that indoor radon levels not exceed 200 Becquerels per cubic metre (Bq/m3). Soil gas control requirements are outlined in the Building Code and detailed in its Supplementary Standard SB-9, “Requirements for Soil Gas Control.” A warranty claim for radon shall include the results of a long-term test (91 days or more). Tests shall be conducted in the lowest level of the home. Testing shall be completed using an approved do-it-yourself radon test kit or by hiring a certified radon mitigation professional. For a list of approved devices and certified professionals, please see Health Canada’s national initiative “Take Action on Radon.” Radon is an environmentally harmful substance and, depending on the radon levels within the home, it may qualify as an emergency situation. For information about the warranty process for emergency situations, please visit Tarion’s website. For additional information about radon, please visit Health Canada’s website.

Action
Basement floor drains not meeting the acceptable condition shall be repaired.
Remarks
Basement concrete floors (slabs) are generally sloped towards a floor drain in order to facilitate water drainage in the event of accidental flooding. The location of the floor drain should be at the lowest point, but may not necessarily be located conveniently to facilitate drainage over the entire floor area. Localized ponding is acceptable. Basement floor drains and grates shall remain clear and unobstructed at all times, and should be inspected and cleaned of obstructions as part of regular home maintenance.

Remarks
Brush coating is not an OBC requirement and absence of brush coating is not a warranted issue. Brush coating is a concrete slurry sometimes applied over poured concrete foundation walls to provide a more uniform finish. Some variation in the colour or texture is acceptable. For surface finishes of exposed cast-in-place concrete foundation wall refer to 1.10. See Also: 1.8 PARGING (NOT BRUSH COATING) IS FALLING OFF ABOVE GRADE
