Abstract
Void-maintaining laminates comprising fuzzy woven or fuzzy membrane layers are provided. Laminates of the present invention comprise at least one sheet-like core element, typically comprising void spaces or channels and, bonded thereto, at least one layer of fuzzy woven composite for use in geotechnical applications. The superior adhesion or bonding of the respective layers to one another, and its contribution to the structural integrity of void spaces or channels, enables the construction and positioning of drainage composites having the desirable characteristics of high permittivity and high transmissivity. Numerous embodiments of the invention are possible. Fuzzy geocomposites of the invention can be used, for example, underneath buildings, foundations, roadways and other paved structures, or in landfills or other types of geotechnical installations to replace or complement conventional drainage materials such as sand, stone and gravel. Methods for making the fuzzy geocomposites are also provided.
