Even seemingly minor evidence of moisture may presage waterproofing distress. Examples include:

· blisters or peeling paint;

· mold, mildew, and vegetative growth;

· dampness or dribbles of water;

· stains and rust;

· odors;

· efflorescence, or white powdery      deposits;

· cracked walls; and

· wood rot.

· Poor preparation. It’s little surprise that poor planning and workmanship account for 90% of all waterproofing failures.

· Incorrect selection of material. Choosing the incorrect material can rapidly cause the failure of waterproofing to occur on any structure.

· Adhesive failure.
