Construction Performance Guidelines
CONCRETE SURFACE IS FLAKING OFF OR “SCALING”
Concrete surfaces shall not disintegrate to the extent that the aggregate is exposed under normal conditions of weathering and use.
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.
Where defective installation or product is determined, the concrete surface shall be repaired.
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.
