Elastoplastomeric anti-root compound certified by the rigorous German regulation FLL 17e/09 concerning root penetration resistance. The heavy-duty spunbond polyester reinforcement endows the product with excellent mechanical characteristics.
GENERAL GARDEN FLL employs a compound consisting in distilled bitumen modified with elasto-plastomeric polymers, atactic polypropylene and anti-root additives; the peculiar qualities of this compound are cold flexibility (-15° C) and high temperature flow resistance (130° C).
These properties improve the resistance to thermal ageing, extending the service life of the membrane over time. The anti-root additive allows the membrane to better resist the piercing action of roots when employed under green roofs.
Good cold flexibility enables easy application of the membrane at low temperatures. This compound, thanks to its special formula, features an excellent resistance to UV ray ageing and allows the membrane to be walked on during application.
The reinforcement employed in GENERAL GARDEN FLL membranes consists in a heavy-weight glass-reinforced rot-proof non-woven polyester fabric. Thanks to its excellent dimensional stability GENERAL GARDEN FLL ensures high performance and avoids shrinkage of the waterproofing surface even if subjected to significant thermal stress.
This reinforcement features good mechanical properties, tensile strength and tear resistance, allowing this membrane to absorb high levels of strain due to structural movements of the building and to withstand both foot traffic and static weights.
GENERAL GARDEN FLL can be used on flat or sloped green roofs, with extensive (shallow) or intensive (rooted) vegetation.
