No action required.
- Condition
- CE 1.6: Exposed Structural Floor Is Out Of Level
- Article Type
- Common Element
- Article Number
- 1.6
- Warranty Year(s)
- One Year
- Performance
- Where a floor structure is intended to be level, the floor shall appear level when viewed from a normal viewing position. Where a floor structure has some slope it shall meet the requirements of the design. Where no design tolerances are specified, a maximum tolerance ratio of 25 mm in 3600 mm applies. Abrupt changes in the surface which create a tripping hazard are not acceptable.
- Warranty
- One-Year - Work and Materials. Ridges and depressions caused by normal shrinkage of materials are excluded from the statutory warranty.
- Action
- Floors with slope beyond the acceptable performance shall have finishes removed, the floor leveled and the finishes reinstated. Visible ridges or depressions exceeding the acceptable condition shall be repaired.
- Condition
- CE 1.7: Concrete Surface Scaling
- Article Type
- Common Element
- Article Number
- 1.7
- Warranty Year(s)
- One Year
- Performance
Concrete surfaces shall not disintegrate to the extent that the aggregate is exposed under normal use.
- Warranty
One-Year – Work and Materials
- Action
The concrete surface shall be repaired.
- Condition
- CE 1.8: Ponding Water on Surfaces
- Article Type
- Common Element
- Article Number
- 1.8
- Warranty Year(s)
- One Year
- Performance
Surfaces which are sloped for drainage may have minor variations in the surface may impede immediate drainage and are acceptable. Standing water with a depth of less than 6 mm and in a pond less than 1m in breadth 24 hours after wetting is acceptable unless it is located in any area of the surface which cannot be easily avoided during normal pedestrian use (examples would be the area immediately beside a doorway or where an individual steps when exiting their parked car or similar) in which case any ponding remaining after 24 hours is not acceptable.
- Warranty
One-Year – Work and Materials
- Action
Ponding in excess of acceptable performance shall be repaired.
- Condition
- CE 1.9: Exposed Cast-In-Place Concrete Is Honeycombed
- Article Type
- Common Element
- Article Number
- 1.9
- Warranty Year(s)
- One Year
- Performance
Cast-in-place concrete exposed to view shall have no honeycombing.
- Warranty
One-Year - Work and Materials
- Action
Walls with honeycombing shall be repaired.
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”.
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.).
