1) It was not properly maintained in regards to vacuuming.
2) This seam was placed next to a staircase. The combination of these two things had cause the carpet to de-laminate from its latex backing.
2) Pet damage.
3) Defective carpet.
Of course these are not the only reasons, just the most common. In this case, who knows? Either way, both sides of the original seam had delaminated to the point that I was actually surprised that it had held together as well as it had.
This carpet repair was performed on Star Valley Ranch, Wyoming.
