Remarks

Efflorescence is the formation of a typically white crystalline deposit on the surface of concrete or masonry foundation surfaces when moisture evaporates from the surface. Efflorescence can be removed using a stiff bristle brush and water. See Also: 4.17 EFFLORESCENCE (TYPICALLY A WHITE POWDERY FILM) IS PRESENT ON MASONRY EXTERIOR FINISHES

Remarks

Some dusting of the concrete surface may normally occur; however, where the aggregate becomes exposed the condition is considered excessive. The colour and texture of a repaired area may not match the surrounding concrete.

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.

Remarks

None

Remarks

Concrete slabs in basements shall conform to the Building Code. Reinforcing of concrete slabs is not usually necessary unless unusual design or construction conditions are encountered. See Also: 14.3 NO REINFORCEMENT IN GARAGE SLAB.

Remarks

It is impossible to completely eliminate all surface voids. At the builder’s discretion a brush coat may be applied. The colour and texture of a repaired area may not match the surrounding concrete. See item 1.15 “Brush coating on above grade poured concrete foundation wall is falling off”

Remarks

Condensation can occur during peak seasonal weather patterns. The homeowner should immediately reduce the moisture levels to prevent harm to property. Dampness can be reduced by using a dehumidifier or by increasing the amount of ventilation to the area. See Also: 1.13 FOUNDATION WALL LEAKS 1.14 WATER LEAKAGE THROUGH BASEMENT FLOOR SLAB

Remarks

Only actual water leakage through the floor slab resulting in an accumulation of water is warranted; dampness or condensation is not considered a warranted condition. The homeowner must take immediate steps to prevent damage to their property and report any losses to their home insurance provider. A thorough site investigation prior to construction and during excavation will assist in determining whether groundwater levels may adversely affect the use of the building. See Also: 1.12 BASEMENT WALL OR FLOOR IS DAMP

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

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

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. Notes Words in italics are defined in the “TERMINOLOGY” section on page 19. This article was added to the CPG on May 24, 2024, and reflects Tarion’s process, which has been in effect since 2013.

Remarks

Wood beams and posts are timbers that are solid-sawn and at least 114 mm (41/2") in their smallest dimension. Some characteristics of drying wood, such as splitting and checking, are beyond the control of the builder and cannot be prevented. Splitting and checking may be an aesthetic issue rather than a structural problem. See Also: 14.23 TWISTING OF OPEN-END BEAMS
