Abstract
A dimensionally stable universal floor covering includes a tufted textile substrate and a reinforcement layer to provide dimensional stability for the entire floor covering. Vacuum, mixing, and injection of compressed air assists in preparing an adhesive and fiber composition to be in the preferred condition and position before the application of pressure to form the reinforcement layer. The universal floor covering is selectively cut and transported in a roll for installation, and it can be conveniently recycled if necessary.
