Repair shall prevent water from penetrating into the building Care must be taken to prevent damage to waterproof membrane during required maintenance activities to exposed surface above the buried roof. The Ontario Building Code references CSA S413, Item 4 which requires protection against leakage. Expansion joints shall be repaired to accommodate movement Exposed to chlorides refers to slabs which are exposed to de-icing chemicals. This typically applies to slabs located below driveways, parking, and walkways. Slabs located below sod or gardens would be considered “not exposed to chlorides”.
Scaling of exterior concrete surfaces including concrete porches, walkways, garage floor slabs, steps (including precast), etc, most often results from salts and de-icers being applied to the concrete surface, e.g. either intentionally for ice melting or unintentionally from road slush deposits. Cleaning salt deposits off concrete surfaces is normal home maintenance. Where repairs are necessary, colour and/or texture may not match the surrounding concrete.
Shrinkage cracks and cracks anticipated in the design do not require repair. Review by a structural consultant may be required to confirm acceptability of cracking.
Some architectural finishes deliberately expose aggregate; this would not be considered scaling. Scaling of exterior concrete surfaces including concrete porches, walkways, garage floor slabs, steps (including precast), etc., most often results from salts and de-icers being applied to the concrete surface, e.g. either intentionally for ice melting or unintentionally from road slush deposits. Cleaning salt deposits off concrete surfaces is normal home maintenance. Feathering the edges of patch materials, which creates a weak edge or installing the patch material too thinly should be avoided. Manufacturer’s installation guidelines should be followed. Concrete is generally not susceptible to scaling in a one year timeframe due to exposure to salt. Deep deterioration that exposes reinforcing would not be considered scaling but rather a structural degradation. This may merit further investigation. Mechanical abrasion caused by the actions of the homeowner is not warranted.
It is normal for water to accumulate on surfaces immediately after a wetting event. Only water which remains after 24 hours is considered ponding.
Honeycombing is a group of holes or voids in concrete caused by insufficient consolidation of the concrete. Random individual pinholes or small voids are not honeycombing. Some honeycombing in areas of the building which are not routinely occupied (mechanical penthouse for example) may be considered acceptable if it does not negatively impact performance (leakage resistance, structural integrity etc.).
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”
Concrete walls naturally crack during curing due to shrinkage. Where lateral or vertical movement is evident, further investigation may be required. The colour and texture of a repaired area may not match the surrounding concrete. See Also: 1.7 CONCRETE BLOCK FOUNDATION WALL IS CRACKED
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.

Flashings must be installed above exterior wall openings and at the top of the foundation (masonry veneer) to direct water to the exterior. Perforations in flashing due to physical damage or chemical incompatibility, deterioration, improper termination and lack of weep holes in masonry veneer can allow water to drain to the interior.
