Recovery piles
Direct crushing of carpet piles or a localized flat pile spoils the appearance of the carpet; especially if you want to move furniture periodically. Try to restore the heap, using some moisture, with a little cold or heat. These tips work best on a wool rug, although they are still worth trying on a synthetic pile, such as nylon or polypropylene.
1) Place the ice cubes over the recesses for a short time and let them melt. Then, when the carpet is almost dry, gently tease back a pile with a small spoon, a coin or the tips of a fork.
2) Place a damp cloth over the grooves. Hold the hot steam iron a few centimeters above it so that the moisture breaks into a pile. Do not allow the iron to touch the carpet pile. Alternatively, use a hair dryer to heat the pile. While it is still warm, use a spoon, coin, or fork tips to gently tease the pile in an upright position.
The way it works is that carpet pile fibers slowly absorb moisture, which helps them to relax, restore and remember their original shape. This allows you to reposition them. If these procedures do not completely restore the flat surface, it may be that the substrate is stretched and plunged into the lining. If so, you will not be able to get the surface level again.
Pile Prevention
There are steps you can take to help reduce the severity of crushing buckets in the future.
1) Be sure to purchase a new thick backing (US: padding) at the same time you install a new carpet.
Choose a lining or gasket that is sufficiently rigid and uniform in design; such as crumb rubber, high-density rubber sponge or compact polyurethane foam. Keep in mind that soft rubber wafers — rippling type or slashing back and large air pockets — can feel good about walking, but they can shrink under concentrated pressure and not recover.
2) Think about how to use furniture cups (glide paths) under your feet for furniture and periodically move furniture a couple of centimeters each time to give the carpet a rest.
3) If this is practical, consider buying a woolen carpet with a thick, dense, twisted or double pile. Wool is naturally corrugated and recovers well from compression.
For better performance, buying a quality carpet with a tightly designed pile will always surpass the freely constructed and open pile.
