Maximum retention volume combined with maximum stability

The channel with enormous retention volumes can collect up to 512 liters per running meter, thus providing immediate near-surface retention space.

In the process, the optimized hyperbola design masters even the highest loads by offering maximum stablility.  
The fact that there is no lateral sheathing (Type I installation) elliminates laborious, cost intensive processing steps. 

Backflow hazards are everywhere

The BIRCOmax-i channel system with steel reinforcement and resistance to load class F 900 safeguards even large paved surfaces during heavy rain.

The elements are layed from above through laying anchors screwed in the thread of the 5 m cast iron frame. 
Up to 3 meter long channel elements guarantee fast laying with a low number of joints.
