Abstract
A process for forming an insulation/waterproofing or a water drainage enhancer/waterproofing barrier on a construction surface by applying directly to said surface a preformed unitary structure comprising a non-porous adhesive sheet like membrane having directly adhered to one surface thereof a cellular board.
Claims11
A process for forming a barrier construction on a structural surface comprising
- (A) transporting barriers to a structural surface to be covered, each of said barriers comprising
- (a) a porous, substantially planar structure having a first and a second major surface and edges defining the dimensions of the structure and said structure having a thickness of from about 0.25 inch to about 10 inches and
- (b) a non-porous bituminous adhesive sheet formed from blends of bituminous material and natural or synthetic rubber or resin, said sheet having a thickness of at least 0.01 inch, a first and a second major surface and edges defining the dimensions of said adhesive sheet, wherein two of the sheet edges extend beyond, are each substantially parallel to an edge of the porous structure, respectively, and are in contact with each other at one corner section of said barrier, and wherein the first major surface of said adhesive sheet is in contact with and self-adhered to the substantially entire first major surface of the porous structure;
- and
- (c) a first protective coating which is coextensive and congruent with the extended portion of the first major surface of the adhesive sheet and a second protective coating which is coextensive and congruent with the second major surface of the adhesive sheet, each of said coatings being removable from and substantially non-adherent to said adhesive sheet.
- (B) removing the second protective coating from the second major surface of the adhesive sheet of a first barrier;
- (C) positioning and applying the first barrier onto a structural surface to cause the adhesive sheet's second major surface to be in contact with a portion of the structural surface;
- (D) removing the protective coating from the extended portion of the first major surface of the first barrier's adhesive sheet;
- (E) removing the protective coating from a second major surface of the adhesive sheet of a second barrier;
- (F) positioning and applying the second barrier onto the structural surface adjacent to that of a previously applied barrier in a manner such that a portion of the second major surface of the adhesive sheet of the second barrier is superimposed on a portion of the extended first surface of the adhesive sheet of the previously applied barrier and the second barrier's porous structure is adjacent to the previously applied barrier porous structure;
- and
- (G) repeating Steps (D), (E), and (F) until the structure surface is covered.

- (B) positioning and applying the first barrier onto a structural surface to cause the adhesive sheet's second major surface to be contact with the structural surface;
- (C) removing the first protective coating from the first extended portion of the first major surface of the adhesive sheet;
- (D) positioning and applying the second barrier onto the structural surface adjacent to that of a previously applied barrier in a manner such that the porous board of the second barrier is adjacent to the porous board of the previously applied barrier and a portion of the adhesive sheet of the second barrier is superimposed on one extended portion of the adhesive sheet of the previously applied barrier;
- and
- (E) repeating Steps (C) and (D) until the structural surface is covered.
