BUILDING CONSTRUCTION COVERDRAIN FT

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.
