Carpet bubbling/buckling explaination

[Joe Appleby]

We'd like to email a video or article explaining to our customers (who have a tackless installation) why their carpets may have buckled in some areas after cleaning. Many times our office's explanation and remedy of "just wait a few days" is not enough.

Thanks

It's not much but it's from the CRI.

Wrinkles, ripples and buckles
Wrinkles, ripples and buckles in carpet are most often caused by a failure to stretch the carpet correctly using a power stretcher, the use of an incorrect or failed cushion, or excessive temperature and/or humidity. Ripples can be caused by a combination of any of the above. If ripples or buckles develop, consult your carpet retailer. Generally, the problem can be corrected by a qualified carpet installer who reinstalls the carpet with a power stretcher.

I know you have heard this before.

No matter how good or true the answer it's still sounds like an excuse after the fact.. This was part of the reason we preinspected for yrs when we had multiple trks. When we were a one pony circus, and did our inspection and clean together, we would report to the client before cleaning if there was any indocation for ripling.
I know sometime you can't tell till after moisture is applied. This is another important reason for grooming, My Helen could tell as she did the final grooming. If the client was there, we would bring them to the affected area, if no one home we would call them at the number they left for us if any unforseeables appeared. or leave a note with the explanation and follow up with a phone call after they arrive back home.

I have several sheets with me explaining all kinds of things so I cover my hind end. When I notice wrinkles I give them as sheet explaining them so they know it's not an excuse. Here is what I use:

Carpet Wrinkles (“Buckles” or “Bubbles”)
Technical Bulletin

Wrinkles, which can be unsightly as well as create trip hazards, accelerate carpet
wear, and cause the carpet to delaminate are rarely a result of manufacturing.
Experience shows that proper installation techniques greatly reduce the potential for wrinkling.

Steps that can be taken during installation to prevent carpet from becoming loose
are:

First, the carpet should be acclimated to the environment in which it is to be
installed. Cold, stiff carpet cannot be properly stretched, and it will eventually become warm, relax, and loose, regardless of how tightly it was originally stretched.

Second, carpet installed via the stretch-in installation method MUST be power
stretched 1 to 1½% over both the length and width of the carpet (CRI-105 1995*,
Section 9.14).

It is mandatory that the carpet be power stretched using power stretchers with
extendable poles, not kicked with a knee kicker. Knee kickers are useful installation tools designed for positioning carpet, not for stretching. Power stretchers with tail pins or spikes, most often referred to as a “stinger” are not to be used because they may damage the face yarns, the primary and secondary backings, the cushion, and possibly even the floor.

Third, use the correct carpet cushion. Cushion that is too thick and too soft (low
density) will allow excessive flexing of the carpet causing it to lose its stretch. CRI
recommends cushion be no thicker than 7/16 inch for residential applications.

Fourth, the tack strip must be adequate to hold the applied stretch. For distances
over 30 feet, use architectural strip with three rows of tacks. Position the strip no more than 3/8 inch from the wall or other vertical surfaces.

Finally, always refer to and follow manufacturer’s installation instructions and/or
the CRI-105 Standard for Installation of Residential Carpet.

The severity of the potential bubbling or wrinkling can often be influenced by
changes in temperature and humidity. In addition, carpet that is loose may also wrinkle and buckle when wet cleaned; however, it will oftentimes return to its original position upon drying.

To correct loose carpet problems, refer to the CRI Technical Bulletin for
restretching carpet.

Very Helpful.
