Roof terraces and esplanades must be protected from water ingress and accumulation under slabs or paving stones. An effective drainage system must be implemented to prevent any damage. COVERDRAIN® FT is intended for rainwater drainage under topsoil or permeable materials (gravel) or concrete slab in contact with an impervious or watertight substrate. The water drained by COVERDRAIN® FT is discharged via collector drains and/or downpipes through the concrete slab. • Alternative solution to the installation of gravel-based drainage • Product approved by landscape architects • Reduced overload on the slab • Savings in materials • Promotes sustainable revegetation • Carbon footprint reduced by 84% by avoiding the use of granular materials • Polypropylene geocomposite • Roll width : 1.95 m • Roll length : 50 m • Output : 1,200 m2 installed per day by two people • 2 diameter of perforated mini-drains : 20 mm and 25 mm • 3 possible distances between mini-drains : 100 cm, 50 cm and 25 cm
