Pole Crush - Roll Crush Marks

The repeating bands running side to side in this hallway are the result of pole crush marks.

Roll or pole crush usually appears across the width of the carpet as areas of the pile yarn that have flattened due to the weight of the roll. Areas of roll crush may appear darker or lighter and are usually identified as widthwise bands. Roll crush is not considered a manufacturing defect. Most roll crush occurs as a result of stacking a large number of rolls on top of one another; this rarely occurs at the manufacturing level since rolls are stored one roll in height.

Roll crush sometimes can be alleviated in carpet using steam or hot water extraction cleaning. Most rolls of carpet will exhibit some degree of roll crush
immediately after the roll has been unwrapped. In most cases, minor roll crush will disappear after the yarn has been allowed sufficient time to "blossom" or undergo moisture regain. All but the most stubborn crush marks in carpet with nylon yarn systems usually can be removed with steam or hot water extraction cleaning.
