Specification text nidagravel®
nidagravel® has been developed for the creation of stable, long-lasting, water-permeable path and road surfaces using gravel.
Extruded polypropylene sheets with a honeycomb structure used for gravel stabilisation. The honeycombs, with a diameter of 49 mm, have a porous geotextile on the underside (hot-glued).
The product is supplied in sheet form.
The sheets are light and pressure-resistant; they are used to give cohesion to granular substrates so that they can allow passing traffic. They are used to strengthen and stabilise ground consisting of gravel or sand.
The sheets are highly resistant against aggressive products, microorganisms and rodents.
Types of nidagravel®:
nidagravel® 140
Ideal for surfaces for car parks and driveways that are used more frequently.
Technical specifications:
- sheet dimensions: 240 cm x 120 cm x 40 mm (L x W x H)
- diameter of honeycombs: 49 mm
- weight empty: 1,8 kg/m²
- weight filled: 80 kg/m²
- compression resistance (filled): up to 400 tonnes/m²
- colour: translucent white
Main physical and mechanical properties:
- mass per surface unit: approx. 1,8 kg/m² and approx. 5,18 kg/sheet
