Interior Concrete Surfaces Are Powdery

Article Number

1.2

Condition

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 statutory 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.
