Drainage channels in high-grade pre-cast reinforced concrete for road networks and motorways.

The channels, with a wall thickness of 47mm, are provided with Z-shaped reinforcement profiles perfectly anchored to the concrete body so that their detachment is prevented during operation.
The profiles, made of materials resistant to corrosion due to contact with the surrounding environment, give the product compactness and protection against wear due to traffic.

The channels feature male-female joints for better stability during installation and a special groove for complete joint sealing.
The BIG47 drainage channels with internal widths of 100 and 150, are classifi ed as Type I and certified, in accordance with standard EN1433, up to load class D400. The grating model that can be combined with channels is slotted with width of less than 20 cm, legally suitable for the transit of people with limited mobility (PRM).
BIG47 channels are provided with assembled gratings, fixed with a system of M10 nuts and bolts (unscrewing bolt). In addition to the BIG47 range, also available are lower drain outlets, sump units with plastic slit buckets and front/end cap in galvanised steel.
The BIG47 range is certified according to European standard EN 1433 and bears the mandatory CE marking.

BIG47 drainage channel range is produced in high-grade vibrocompressed concrete ensuring high resistance to compression (minimum strength class C35/45 – fck = 35 N/mmand Rck = 45 N/mm2), resistant to frost and de-icing salts (marking “+R” for European standard EN 1433) and attacks caused by atmospheric agents (“W” marking for European standard EN 1433)
