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.
