Drainage Material
Optigrün uses the tried-and-tested Perl bulk material drainage systems in the multi-layer system structures of extensive and intensive green roofs.
Depending on the region, mineral bulk materials include expanded clay, lava or bricks. Crushed grains in the range of 2-12 mm for extensive green roofs and intensive green roofs without water accumulation; partially crushed grains 8-16 mm for intensive green roofs with water accumulation.
Natural material, easy to recycle, drainage system for flat roofs, natural water reservoir that keeps the water available for plants: approx. 8 litres/m² at an installation height of 50 mm (pore storage). Supported by the WKK water channel for long flow lengths. Simple levelling of uneven roofs.
Drainage Material Perl 2-10 BT
Optigrün Drainage Material Perl 2/10 BT is used as an especially lightweight drainage layer beneath extensive and intensive green roofs and for pressure resistant filling of Drainage Boards on roof structures with low load reserves.
Drainage Material Perl 2-10 LA
Optigrün Drainage Material Perl 2/10 Lava is used as a drainage layer beneath intensive green roofs without water accumulation, for pressure-stable filling of plastic drainage boards and as a pressure resistant drainage and levelling course beneath paving.
Drainage Material Perl 8-16 LA
Optigrün Drainage Material Perl 8/16 LA is used as a drainage layer beneath intensive green roofs as pressure resistant drainage and levelling course beneath paving.
Drainage Material Perl 2-12 ZS
