Abstract

Abstract An insulative waterproof drainage material is presented. The insulative drainage system comprises, in part, a plastic sheet having a plurality of alternate valleys and raised portions in the sheet defining a core. Preferably, the core leads to a slotted pipe. The core has two opposing surfaces. One surface has a water previous fabric material attached thereto while the other surface has a layer of thermally insulative material, preferably a polymeric foam material thereon. The foam or other insulative material has a pre-selected thickness which provides a sufficient R (thermal) value. This insulative drainage system is formed into panels and then adhesively applied to the exterior of a foundation or other retaining wall using any suitable and well known adhesive. Preferably, each panel is provided with interlocking joints which permit a watertight fit between adjacent panels.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 108 words
An insulative waterproof drainage material comprising: a sheet of rigid material having a plurality of hills and valleys therein to define a core, said core having opposed surfaces; permeable fabric material attached to one of said opposed surfaces; a layer of thermally insulative material on said other of said opposed surfaces, said insulative material having a first surface covering said hills and valleys and having a second surface oppositely disposed from said first surface defining an outer surface, said outer surface being spaced a pre-selected distance D from said hills of said core, said pre-selected distance D defining an insulative material thickness corresponding to a pre-selected thermal value.
Claim 2
Dependent Claim 108 words
An insulative waterproof drainage material comprising: a sheet of rigid material having a plurality of hills and valleys therein to define a core, said core having opposed surfaces; permeable fabric material attached to one of said opposed surfaces; a layer of thermally insulative material on said other of said opposed surfaces, said insulative material having a first surface covering said hills and valleys and having a second surface oppositely disposed from said first surface defining an outer surface, said outer surface being spaced a pre-selected distance D from said hills of said core, said pre-selected distance D defining an insulative material thickness corresponding to a pre-selected thermal value.
Claim 3
Dependent Claim 17 words
The material of claim 1 including: adhesive material on said outer surface of said thermally insulative material.
Claim 4
Dependent Claim 12 words
The material of claim 1 including: a slotted pipe along said core.
Claim 5
Dependent Claim 15 words
The material of claim 1 wherein: said thermally insulative material is a foamed polymeric material.
Claim 6
Dependent Claim 14 words
The material of claim 4 wherein: said foamed polymeric material is polyurethane or polystyrene.
Claim 7
Dependent Claim 28 words
The material of claim 1 wherein: said core, permeable fabric and insulative material define at least one panel and including: means for interlocking said panel with another panel.
Claim 8
Dependent Claim 31 words
The material of claim 6 wherein said interlocking means comprises: said panel having an edge and wherein said edge includes a protrusion and a shoulder, said shoulder being adjacent said protrusion.
Claim 9
Dependent Claim 11 words
The material of claim 2 wherein: said adhesive is water proof.
Claim 10
Dependent Claim 14 words
The material of claim 8 wherein: said adhesive is a urethane modified tar coating.
Claim 11
Dependent Claim 14 words
The material of claim 1 wherein: said core is comprised of a plastic material.
