FILDREN, the double-wall slotted corrugated pipe wrapped in a geotextile fibre filter fabric for underground drainage applications. The coatings sheath effectively filter any impurities and soil that could block the slots or enter the pipe together with the drained fluids. The sheathing guarantees the effectiveness of the draining action of the pipe over time.
Supply and laying of double-wall corrugated PE pipe made by continuous co-extrusion of the two walls, with equidistant slots of variable size, position and number, distributed throughout the circumference, located on the bottom of the groove between two consecutive corrugations; manufactured by a company with UNI EN ISO 9001:2008 certification and UNI EN ISO 14001:2004 environmental certification. The pipe must be entirely black with a co-extruded longitudinal green band on the outside, packed in 25/50 meter rolls, and fitted with a coupling and wrapped in a geotextile fibre filter fabric. The manufacturer must supply the relevant construction specifications and product test certificate.
