XF Drain - highly permeable geo-composites that combine drainage, filter, aeration and water retention functions in one product.
Depending on the version, we incorporate a non-woven filter fabric to one or both sides of the drain core. This also protects the roof membrane and supports the vegetation, promoting drainage and root aeration. We can also add an optional retention fleece to provide water and nutrient storage.
XF Drain is 95% open thanks to its 3D fused, entangled filaments core and permeable filter fabric, which facilitate water and vapor movement. This enables topside venting and maintains open diffusion above the extruded polystyrene rigid insulation, therefore suitable for PMR applications.
XF Drain consists of a 3D entangled polymer filament core that is thermally bonded to one or two fabrics. Unlike dimpled drains, XF Drain's design configuration prevents fabric intrusion under load and maintains high flow rate under soil conditions.
XF Drain is lightweight, flexible, lays perfectly flat for quick easy installation. The textile-based mat cuts easily, fits to curves and contours, and does not create sharp edges when cut.
Lightweight, low profile, high flow rates.
Open filament design creates 360° flow opportunities.
High compressive strength and resilient under high loads.
40%+ post-industrial recycled content contributes to LEED points.
Water retention option for arid climates and stormwater management.
Customized drainage products for specialized green roof applications.
Extensive green roofs weigh less, need little or no maintenance, help save energy and water, and support bio-diversity.
An effective green roof drainage mat is critical for a successful installation, and brings environmental benefits.
Planting a green roof in situ with sedum cuttings or plug plants, and then caring for it, can be satisfying and affordable.
Stabilises green roofs – no need for hydromulch or wind netting, and you have flowers and foliage all year round.
