Stabilizing a textile sheet structure was achieved by forming a plurality of discrete fiber tufts extending from a first face of a fibrous layer of the textile sheet structure, through the fibrous layer and beyond a second face opposite the first face. Each discrete fiber tuft included a plurality discrete fibers. Each discrete fiber tuft was anchored to the first face and the second face of the fibrous layer by joining together the plurality of each discrete fiber tuft at the first face and the second face and bonding the joined plurality of discrete fiber tuft to the first face and the second face.

A system of built-in, closely spaced passageways or piping containing numerous, small, closely-spaced holes, provided as an integral or separate part of the underlayment in a typical wall-to-wall carpet flooring installation. The piping network includes a manifold and access port which can be quickly and conveniently connected, from above or below the floor, to a typical motorized water pump or vacuum device, for the purpose of suctioning and drying large quantities of standing water, caused by accidental flooding for example, from within the carpet without the need for costly emergency professional services and equipment as is the norm today. The pump could be connected either from above or below the carpet floor as desired for convenience. The system can be provided at the time of new carpet installations or as a retrofit kit for existing installations and is scalable to any size of floor area in homes or buildings.
