Flexible Polypropylene Alloy (FPA). Combining the advantages of Polypropylene (PP) with those of Ethylene Propylene rubber (EPR) to create a highly flexible membrane with excellent heat-weldable attributes.
Flexible – conforms well to sub-grade irregularities and protrusions, as well as settlement and subsidence under stress
Is tough and Copes with steep side slopes
Environmental resilience – outstanding resistance to stress cracking, aggressive chemicals, weathering and UV
Standard welding techniques deliver high joint integrity because of the wide melt transition window
Easy to field-repair
Site installation uncertainties eliminated with our pre-fabricated service
Low permeability to gases, meeting many codes for municipal solid waste landfills
