The new number one
BG-FILCOTEN one
It’s finally here: the first monolithic channel for dynamic loads made from FILCOTEN HPC, a high-performance concrete. After undergoing an intensive development phase, we are now presenting a drainage system that combines this structure with outstanding features and transparent sustainability.
A drainage channel – and a milestone
Monolithic channels have been around for about 20 years. While the idea of developing this kind of system from a mineral, cement-bound material isn’t new, it’s a great challenge, and no manufacturer has been able to meet it so far. We have put in a lot of work, broadening the limits of our mold construction and adding sophisticated features. Following intensive construction, design, planning and testing phases, we have finally reached our goal: adding a monolithic system to our products in the box drain and water management range.
Steffen Bernauer (Manager Product Development at BG) on the development process:



Why monolithic?
BG-FILCOTEN one is made from one piece, which makes it extremely robust, wear-resistant and highly sustainable. It is ideally suited for the dynamic loads occurring in parking and airport areas as well as on highways. Thanks to the monolithic structure, using a traditional casting grate is no longer necessary, as the entire channel system is made from highly-solid FILCOTEN HPC. Another advantage of the monolithic structure: no loosening of components due to frequent traffic or heavy loads.
Sustainable like no other
Karl-Heinz Gramlich (Director Product Management) on BG-FILCOTEN one:



Throughout the assessment, all environmental indicators that we impacted ourselves were analyzed and verified. As an example, this includes primary energy consumption of non-renewable energies, assessed water requirements and greenhouse gas emissions as the most important indicators for the lifecycle phases of raw material procurement, production, internal logistics and transport to the construction site.
The fact that we are committed to 100 % green energy and resource-saving use of material positively impacted the assessment, as did our FILCOTEN HPC construction material. By publishing the results, we give our customers the opportunity to integrate our data into the environmental lifecycle assessment for their construction projects.
FILCOTEN HPC is purely mineral and styrene-free. The high-performance concrete is 100 % recyclable and has been tested for solvents, resins, biocides, VOCs as well as heavy metals, meeting the strict criteria of the Institute for Biologically Sound Construction Rosenheim (IBR).
Naturally beautiful
Thanks to its monolithic structure, BG-FILCOTEN one, made from FILCOTEN HPC, is also a highlight when it comes to appearance. The high-quality channel body with its typical concrete color surface in an exposed concrete style blends in perfectly with the surroundings.
The system at a glance
Since we added a whole range of intelligent solutions, BG-FILCOTEN one is greater than the sum of its parts. These solutions ensure more efficiency, safety and performance when installed, used and maintained.
- Optimized intake openings
- Groove/spring/pin system for easy installation and fitting
- Highly efficient water run
- Intelligent sealing system
- Revision element
The optimized intake openings for efficient rainwater intake are most visible for road users. They can be safely driven and walked across thanks to their counterrotating radial arrangement.
The groove/spring/pin system that can be installed in either direction enables easy and quick installation and precise, correctly aligned fitting of elements. Planning and installation of the system is simplified, as there are fewer individual parts. The adapter, front and end plates are also equipped with the groove/spring/pin system.
The channel cross-section in a wave profile design ensures maximum hydraulic capacity at partial and complete filling. Swirling of the inflowing water enables excellent self-cleaning properties.
The optional seal is simply inserted into the circumferential groove on the channel body. Integrated lamellae on the sealing profile prevent it from slipping out. The groove and spring system ensures optimal sealing.
The revision element in the style of a channel run comes with a removable class F900 grating for easy cleaning of the drainage unit.
FILCOTEN® one is available in the nominal widths 150 and 200 and construction heights no. 0 (335 mm) and 40-0 (535 mm). The latter offers a more powerful hydraulic performance and an additional retention volume of 40 l/m. Both construction heights can be combined without difficulty.
A BG-Graspointner quality channel
We orient our everyday activities on our most important corporate values: sustainability and innovation.
