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
