About

A Geomembrane used for lining ponds (to reduce Groundwater Recharge (to preserve Water Level and/or to prevent pollutants from causing Groundwater Contamination ) )
- If Used for Roofing:
- Pros: cost-to-performance ratio is 4-6 times better for integrated ballasted roofing assemblies. About 2-3 more puncture-resistant than EPDM [1]. At about 1/2 the cost - so overall performance (cost and puncture) is 4x-6x
- Cons: less flexible than EPDM for doing corners

40 mil - 378 lb puncture proof (per what area?)- [3]
20 mil - 40 year covered, 10 year exposed. 18x50 - $408 - free ship. [4]. 50 cents/sf.

30 mil 18x20 with ship is $232 at about 58 cents/sf. [5]
- Regarding size: "It would come as one piece but it may be heat welded for the width/length as I believe the max roll width is 12ft. All items are custom cut - we do not have pre-cut stock pieces of this product."
- Possibly use tar paper as another layer of protection on top.
30 mil - 25x40 - 40 year when covered, 10 year when exposed -[6]. 25x45 - $1030 [7] or $1/sf.
