In general, the rainwater from terraces or balconies is drained using receivers of medium or small drainage capacities. Receivers for terraces and balconies from HL allow the drainage of surfaces between 16sqm and 100sqm with a single receiver (considering rain intensity of 300 l(secxha).
Thus, the range of receivers for these applications includes receivers for terraces, with high drainage capacities, made of PP, with side (D75mm) or vertical (D75/110mm) outlet connections, as well as receivers with lower drainage capacities, for medium and small terraces or balconies, made of PE, with side (D40/50/75mm) or vertical (D50/75/110mm) outlet connections.
As a result, HL offers the possibility of building terraces with even a single rainwater drainage point. To choose the appropriate receivers and accessories, it is necessary to know the detailed plan of the terrace structure (ceiling material, thermal insulation, waterproofing used, the existence or not of diffusion membranes or condensation barrier, layer thickness, etc.).
