THE REPORT
Site Conditions and Geographical Information
The carpet was installed in a single story building in a commercial zone. The building was occupied at the time of the inspection. The condition and maintenance of the property were good.
BACKGROUND INFORMATION MADE TO THE INSPECTOR
Immediately after the installation, lines were noticed. Corrective services were suggested but were not done.
According to the dealer, the carpet was stored in a bin with two rolls on top of the one installed. He believes that the problem is correctable or will fix itself in time.
DESCRIPTION OF PROBLEM AREA BY THIS INSPECTOR
The carpet had width-wise lines that ran continuously and intermittently across the carpet. The lines had the appearance of nap crushing. On the first panel, the lines measured 2, 5, 9, 12 feet apart. The panel next, lines were 1, 3, 4, 5 and 6 and 1/2 feet apart.
ON-LOCATION FIELD TESTING
The carpet was steamed and the lines disappeared.
THE ISSUE OF THIS REPORT
The question that I have been asked to address is caused the widthwise lines?
GUIDELINES FOR EVALUATING THE ISSUE
Widthwise Lines Can Be Caused From
1. Storage from Roll Crushing
2. Manufacturer's defects from
-stop marks
-tension variations on the beam
3. Installation errors
-lack of stretching
-improper bending or fold marks
-when cushion seams separate, such as when there is no duct tape covering the seam
INDUSTRY STANDARDS, PRACTICES & DEFINITIONS
According to the CRI 104 - 1994, the storage and handling standards are as follows:
5. STORAGE AND HANDLING Environmental conditions prior to and immediately after installation shall meet the following criteria to assure a "relaxed" carpet, preventing glue-down or stretch-in problems.
5.1 Storage Carpet shall be stored in flat bins to prevent pile crush. Temporary storage shall be in flat bins with a maximum height not to exceed three rolls.
THE INSPECTOR'S ANALYSIS
Flat marks in the carpet are created either by roll-crushing or fold marks, thus this rules out problems inherent in manufacturing. Either condition is not considered a manufacturing defect. Roll crushing distinguishes it from other types of widthwise lines by appearing at progressively longer or shorter distances from one another and the width of the lines is generally a few inches. This is brought about by rolls being stacked upon one another in storage and being left for some period. Normally this condition will correct itself by use or can be aided by steaming. If it does not correct with time or steaming, then there might be a defects in the latex or in the way the carpet was stored.
CONCLUSION
The lines in the carpet in question were created by roll crushing based upon the widthwise direction and the crushed yarns.
