seams should be fused together with seaming tape and edges sealed with super special glue. Installers often do not properly stretch and seal seams. Improper stretching techniques can lead to the cushion backing breaking down prematurely. Unfortunately the carpet can form ripples as a result of the dreaded delamination. When failing to seal seams can lead to yarns pulling away and creating fraying.
Carpet cushions can help prevent over matting and fibers becoming crushed.
