A cross-laminated, high-density polyethylene geomembrane. Permalon's patented construction yields the best weight to strength ratio available and also provides exceptional tear and puncture resistance. No material offers a better balance of properties or more proven performance and reliable durability for the creation of waterproof tanks in greenroofs, on podiumdecks, in SUDS applications or underneath trees and green space in the urban environment.
Designed to be lightweight and easily handled, Permalon offers the possibility to be factory made to size, to minimize in field welding of liners. Individual panels of an acre in size are readily done. When properly installed, this material should last indefinately. Permalon is resistant to root penetration and microbes.
“The units are designed with tomorrow’s world in mind. Made from 100% recycled materials now, and again 100% recyclable in the future.”
