100% vegetal on fertile foundation - complete O2D system

The O2D GREEN® pre-grassed system and the TTE® Multidrain^Plus system for grassing constitute a combination of TTE® Multidrain^Plus support grids, grass infill and drainage-enhanced load-bearing fertile foundation materials.

This permeable floor covering permits the deployment of green parking spaces, permeable grassed parking spaces, grassed emergency service access roads, permeable green roadways, squares and internal courtyards. The O2D GREEN® pre-grassed system or the TTE® Multidrain^Plus system for grassing combine permeability with the long-term sustainability of grassing.

TTE® green systems provide multiple benefits:
- Technical advantages: optimum load-bearing and load distribution capabilities (exceptional static load resistance: 10 Newtons/mm², equivalent to 1,000 tonnes/m²), optimum protection of the root system of grass provided by a 14 mm cellular wall thickness and substrate filling to a level of -1 cm
- Applications: flexibility of design and adaptability to applications associated with the versatility of infills (with a single base structure for different grass, paving or gravel infills/ option for the formation of markings or tread surfaces)
- Environmental benefits: conservation of water resources, greening of spaces, promotion of the biodiversity of soils, reduction of the urban heat island effect

TTE® Multidrain^Plus grids constitute an eco-material generated by a high-grade recycling system, produced from recycled household wastes (using the German DUAL system). Recycled, recyclable and reversible, this material contributes to the achievement of a circular economy. The permeable surfacing systems developed by O2D ENVIRONNEMENT are recommended in the context of eco design projects, incorporating the natural infiltration of rainwater and the provision of green surfaces.

Applications: drainage-enhanced parking spaces, permeable parking spaces, drainage-enhanced parking facilities, green parking spaces, grassed parking spaces, permeable and green squares and internal courtyards

Specifikáció

Technical information on the fertile foundation material for light vehicle parking with O2D GREEN® pre-grassed grids and TTE® Multidrain^Plus grids for grassing
Composition :
• 15 cm thickness: TP GREEN soil and stone foundation material
o 75% crushed material of particle size 20/40 mm
     o 25% organic substrate (topsoil/washed sand/compost) of particle size 0/10 mm
• 3 cm thickness: LP GREEN fertile bedding course
     o 60% crushed material of particle size 4/6 mm
     o 20 % topsoil/loam mixture of particle size 0/10 mm
     o 20% sand of particle size 0/4 mm
Prepared base/sub-base (-23 cm in relation to level 0):
• The requisite permeability below this foundation system is such that K > 10^-6 m/s
• The load-bearing level required is such that EV2 > 40 MPa (EV2/EV1 < 2)
• We recommend the installation of a permeable anti-contaminant geotextile membrane
This fertile foundation material composition ensures both load-bearing and drainage capabilities, and provides the requisite nutrients for the effective rooting of grass. It is recommended that the thickness of the sub-base (for example, 20/40 mm crushed drainage gravel) should be adjusted and/or any other facility should be incorporated, if the natural ground surface does not possess the requisite infiltration properties, or for the satisfaction of project design requirements. The load-bearing level should be appropriate to the intended application.
