Construction Performance Guidelines
Article Number
Condition
CONCRETE SURFACE IS FLAKING OFF OR “SCALING”
Acceptable Performance/Condition
Concrete surfaces shall not disintegrate to the extent that the aggregate is exposed under normal conditions of weathering and use.
Warranty
One-Year. Work and Materials · Surface deterioration due to owner-applied substances, improper maintenance, or normal wear and tear is excluded from the statutory warranty.
Action
Where defective installation or product is determined, the concrete surface shall be repaired.
Remarks
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.
