Waterproofing membrane
A waterproofing membrane comprising a structure incorporating a fiber layer and wherein to one side of said structure a bituminous mass is applied and another side of said structure is covered on its surface with a substance comprising a mineral or organic filler and an acrylic polymer, whereby said substance comprises between 15% and 25% by dry weight of said acrylic polymer and mixed therewith between 4% and 22% by dry weight of titanium dioxide.
1. A reflective waterproofing membrane for application over a surface area of a structure, the waterproofing membrane comprising a structure incorporating a fibre layer and wherein to one side of said structure a bituminous mass is applied and another side of said structure is covered on its surface with a reflective substance comprising a mineral or organic filler and an acrylic polymer, and wherein said reflective substance comprises between approximately 15% and 25% by dry weight of said acrylic polymer and mixed therewith between approximately 4% and 22% by dry weight of titanium dioxide.
2. The waterproofing membrane of claim 1 wherein said substance comprises approximately 21% to 23% by dry weight of said acrylic polymer and approximately 7% to 8% by dry weight of said titanium dioxide.
3. The waterproofing membrane of claim 1 wherein said substance further comprises between approximately 60% and 75%, preferably approximately 70%, by dry weight of CaCO 3 .
4. The waterproofing membrane as claimed in claim 1 wherein said bituminous mass comprises a quantity of olefinic polymers with an intrinsic crystallinity lying between approximately 1% and 5% of the concentration of polymers present in the bituminous mass.
5. The waterproofing membrane of claim 1 wherein said bituminous mass is formed by either an Atactic Polypropylene (APP), an Atactic Poly Alpha Olefin (APAO) or a Thermoplastic Polyolefin (TPO).
6. The waterproofing membrane of claim 1 wherein said bituminous mass is formed by a Styrene Butadiene Styrene (SBS).
7. The waterproofing membrane of claim 6 wherein said SBS comprises at least approximately 8% of thermoplastic elastomer.
8. The waterproofing membrane of claim 1 wherein said substance also comprises a dispersion, an anti-foaming and a thickener.
9. A waterproofing membrane comprising a fibre layer having a first side and a second side and wherein a bituminous mass is applied to the first side, and the second side is substantially covered on its surface with a substance comprising a mineral or organic filler, a polymer, and a material having a high reflective index.
10. The waterproofing membrane of claim 9 wherein said polymer comprises an acrylic polymer.
11. The waterproofing membrane of claim 9 wherein said material having a high reflective index comprises titanium dioxide.
12. The waterproofing membrane of claim 9 wherein said substance comprises between approximately 15% to 25% by dry weight of said polymer and mixed therewith between approximately 4% and 22% of said material having a high reflective index.
13. The waterproofing membrane of claim 9 wherein said substance comprises between approximately 21% to 23% by dry weight of said polymer and mixed therewith between approximately 4% and 22% by dry weight of said material having a high reflective index.
14. The waterproofing membrane of claim 13 wherein said substance further comprises between approximately 60% and 75%, by dry weight of CaCO 3 and said material is titanium dioxide.
15. The waterproofing membrane of claim 9 wherein said bituminous mass comprises a quantity of olefinic polymers with an intrinsic crystallinity lying between approximately 1% and 5% of the concentration of polymers present in the bituminous mass.
16. The waterproofing membrane of claim 9 wherein said bituminous mass is formed by either an Atactic Polypropylene (APP), an Atactic Poly Alpha Olefin (APOA) or a Thermoplastic Polyolefin (TPO).
17. The waterproofing membrane of claim 9 wherein said bituminous mass is formed by a Styrene Butadiene Styrene (SBS).
18. The waterproofing membrane of claim 17 wherein said SBS comprises at least approximately 8% of thermoplastic elastomer.
19. The waterproofing membrane of claim 9 wherein said substance also comprises a dispersion, an anti-foaming and a thickener.
20. A waterproofing membrane comprising a fibre layer having a first side and a second side and wherein a bituminous mass is applied to the first side, and the second side is substantially covered on its surface with a substance comprising a mineral or organic filler, a polymer, and a material having a high reflective index providing a reflection of at least approximately 85% of visible light.
21. The waterproofing membrane of claim 20 wherein said material having a high reflective index reflects approximately 95% of infrared light.
