Dear construction experts,

I have doubts about the quality of the installation of the needle-punched carpet in our office area. There are always gaps visible between the individual rolls. Also, a light strip is almost always noticeable along the seams.

The whole process didn’t start well. After priming, the leveling compound was applied. The next day, about 20% of the surface was cracked, with some areas lifting. So those sections were knocked out, re-primed, and the leveling compound reapplied.

After drying, the priming (yellow) was applied again on the leveling compound. Then the adhesive was spread using a notched trowel, and the needle-punched carpet (2m roll) was installed. What caught my attention was that the carpet was only pressed down using a spirit level lying on the floor and feet.

Today I inspected the result. In my opinion, the seams are too wide. In other offices, these joints are only noticeable upon very close inspection. Here, every seam is clearly visible. In some places, the carpet edges are slightly raised or even completely lifted.

I have looked into it. For example, I found information stating that needle-punched carpet must be rolled with at least a 50kg (110 lbs) roller and re-rolled after 45-60 minutes. That definitely didn’t happen. Aside from feet and the spirit level, nothing else was used.

The supervisor I called with my concerns said, “A roller isn’t necessary, this is a wet adhesive that doesn’t require it.” He plans to inspect the seams tomorrow.

Please take a look at the photos and let me know if this is still acceptable or if it constitutes a defect.
Thanks and best regards,
Knollox
