PermaFlex 700

A polythene reinforced cross-laminated, LDPE waterproof membrane. 

High quality

Its patented construction yields the best weight to strength ratio available and also provides exceptional tear and puncture resistance, while remaing foldable to create corners and edges. No material offers a better balance of properties or more proven performance and reliable durability for the creation of waterproof tanks for blue-greenroofs, on podiumdecks, in SUDS applications or underneath trees and green spaces in the urban environment. Waterproof liners can be manufactured to specification for your project, or easily and reliably heat welded on site by an experienced crew.
