Adherent layer

摘要

The present disclosure describes embodiments of an adherent layer that may be used to attach a geo-membrane to a concrete slab and methods that include installation of the adherent layer. The adherent layer can be used to inhibit the geo-membrane from becoming disengaged with the concrete slab and can thereby help prevent water from penetrating the geo-membrane and causing moisture damage to the structure above.

主权项

1. An adherent layer for sealing a seam between a first geo-membrane sheet and a second geo-membrane sheet and for forming a bond to concrete poured atop the adherent layer, the adherent layer comprising:
a substrate; a first adhesive layer applied to a top of the substrate; a second adhesive layer applied to a bottom of the substrate; and a textured layer applied to the top of the substrate and over the first adhesive layer, the textured layer forming the bond with the concrete poured atop the adherent layer, wherein the textured layer includes:
a first set of fibers oriented adjacent respectively to each other, anda second set of fibers oriented adjacent respectively to each other, oriented transverse with respect to the first set of fibers, and further oriented so as to form protrusions from a surface of the textured layer, wherein respective adjacent fibers of the first set of fibers are spaced apart in a range of about 30 mils to about 60 mils to provide space in which concrete enters between the first and second sets of fibers when poured thereon, and wherein a thickness of the textured layer ranges from about 10 mils to about 30 mils.
