Foundations

1.2

Interior Concrete Surfaces Are Powdery

Acceptable Performance/Condition
Concrete surfaces shall be sufficiently hard to prevent powdering which results in exposure of the aggregate.

Warranty
One-Year Work and Materials
Surface deterioration due to owner-applied substances is excluded from the warranty.

Action
Where powdering occurs exposing the aggregate the concrete surface shall be repaired to provide a hardened surface.

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.
