COVERDRAIN FT - Drainage of roof terraces, esplanades and sports grounds
Use
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.
Benefits
- 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
