Summary for decision-makers

Alkern, a pioneer in the French market, recently expanded its product range with individually verified Environmental and Health Declaration Sheets (FDES) for its concrete drainage slabs. These innovative products, including Betogreen'C, Betogreen'O, Quadro, and Hydrodalle, are designed to meet the growing demands of public and private decision-makers for technical performance and environmental transparency.

By obtaining these FDES, Alkern positions itself as a key player in promoting sustainable solutions for outdoor developments. These sheets provide specifiers with reliable data on environmental impact, thus facilitating the implementation of soil de-impermeabilization and rainwater management projects.

Frequently Asked Questions for Decision Makers

What FDES are offered by Alkern?

Alkern offers verified FDES for Betogreen'C, Betogreen'O, Quadro, as well as for its Hydrodalle slabs, all suitable for various outdoor installations.

What are the advantages of these EPDs for decision-makers?

Alkern's EPDs provide transparency on the environmental impact of products, making it easier for decision-makers to prescribe sustainable and efficient solutions for their projects.

Where can these FDES be downloaded?

The FDES are accessible and downloadable on the INIES database website, ensuring easy availability for professionals in the sector.

Rainfall management has changed, with long periods of drought alternating with periods of more intense rainfall than in the past. Based on this observation, Alkern has developed a range of drainage solutions that adapt infrastructure to the effects of climate change.

Alkern, the first French manufacturer to obtain verified individual FDES for its concrete drainage slabs

Having recently expanded its range, with no collective FDES existing for these products, Alkern is establishing itself in this 2025/2026 school year as a pioneer as the first French manufacturer to obtain Individual FDES (Environmental and Health Declaration Sheets) verified for its concrete drainage slabs : Betogreen'C, Betogreen'O, Quadro, Hydrodalle simple and Hydrodalle double.

By taking this new step in favor of more responsible exterior developments, Alkern is thus distinguishing its offers to decision-makers and public clients looking for solutions combining technical performance and environmental transparency.

Obtaining these individual FDES verified and available on the INIES database ensures that they can prescribe responses with controlled environmental impact, for the implementation of soil de-impermeability projects, sustainable rainwater management or even the fight against urban heat islands.

Remember that Betogreen'O and Quadro (11,6 kg CO2 eq/m2) are designed to create stable and walkable green spaces. Betogreen'C, on the other hand, is perfect for parking lots or driveable areas that you want to plant. Finally, Hydrodalle (15,8 kg CO2 eq/m2) allows you to landscape traffic areas and is compatible with all types of vehicles.

Finally, let us mention that Alkern offers, within its O' range, a diversified range of draining paving stones such as Hydrojoint, Aquafil, or even Pavé Coquillage, also covered by FDES (collective FDES from CERIB).

Note that, always with a view to meeting a need for knowledge on a finished product, the calculations and the production of the FDES for Alkern products were carried out on the one hand without filling*, thus allowing its customers a calculation of their greenhouse gas balance sheet precise and validated by a third party authorized by the INIES program, across the entire value chain. On the other hand, by measuring more than 15 environmental indicators with filling included*, by gravel or by vegetated earth-sand mixture, these new FDES make it possible to know the carbon impact of the coatings produced.

*Seat included in all cases.
