For drainage of surfaces in areas undergoing heavy-duty transport; also for areas where the architectural and flexibility demands are especially high. 7 nominal widths, lengths up to 2 metres and our large selection of gratings.
For safely laying lines and pipes in heavily frequented, high-traffic industrial and public areas. 8 nominal widths, construction lengths of 1.0, 1.5 and 2.0, with or without steel angles, with or without integrated Halfen profiles, also suitable for drainage.
For drainage of areas subjected to high levels of dynamic horizontal forces and high traffic heavy-duty transport areas. 2 nominal width, C 40/50 reinforced concrete, construction lengths 1.0 and 2.0 metres, with and without zinc surface protection.
For everywhere subject to heavy traffic where substances hazardous to water such as fuels, mild lye and acids accrue. 5 nominal widths, construction lengths: 0.5, 1.0, 2.0 metres, officially certified.
For drainage of areas subjected to high levels of dynamic horizontal forces. Resistant against mildly aggressive agents. 3 nominal widths, made of reinforced C 40/50 concrete, construction lengths: 1.0, 1.5, 4.0 metres, with official certification.
BIRCOsolid® reinforced concrete slot channels are ideal for use anywhere that is subjected to extreme loads where groundwater protection is required. Profile 200/300, made of reinforced C 40/50 concrete, officially certified.
BIRCO cast covers guarantee flexibility in their utilisation and in construction possibilities, above all through enormous load reserves. Black-immersion lacquered spherical cast or galvanised cast, construction length 0.5 m.
The galvanising process sees the metal coated with a zinc layer to protect it from corrosion. BIRCO covers are hot galvanised so that all of the edges and openings are evenly coated and the protection from weathering. Construction length: 0.5 and 1.0 m.
