Firemen access on fertile foundation - complete O2D system

The green systems for firemen access roads (O2D GREEN® pre-grassed system and 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, adapted to firetrucks traffic.

This permeable floor covering permits the deployment of grassed emergency service access roads or permeable with a mix of grass and paving. The O2D GREEN® pre-grassed system or the TTE® Multidrain^Plus system for grassing combine permeability with the long-term sustainability of grassing.

A chevron layout pattern is employed (grid dimensions: 80 x 40 cm), and physical edging structures are provided.
Emergency service access roads feature a standard width of 400 cm. Naturally, it is possible for dimensions to be adapted.

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 | Puncture resistance > 100 kN on a surface of diameter 20 cm), 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: green emergency service access roads, green firemen access roads, permeable emergency service access roads, permeable firemen access roads

Technical information on the fertile foundation material for emergency service access roads 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
The load-bearing level required on the soil and stone foundation material is such that EV2 > 60 MPa (EV2/EV1 < 2)
• 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 > 60 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.
