Alkern publishes its “Guide to draining solutions for roads and urban development” and expands its answers with the Quadro draining slab

This 44-page collection, educational and richly illustrated, raises awareness among professionals about the consequences of soil artificialization and distils solutions to combat heat islands. Giving pride of place to the permeabilization of urban soils as a concrete, immediate and sustainable response, the guide details in particular the advantages of the beneficial albedo effect that Alkern solutions can offer.

Remember that Alkern's O' range, 100% natural and recyclable, guarantees high permeability making it possible to infiltrate sustainably at least twice the precipitation of rain qualified as intense (source Etude du Graie de Lyon).

Alkern draining solutions guarantee exemplary permeability of public spaces*, whether they are affected by vehicle traffic, parking or pedestrian use.

Likewise, if Alkern offers a range of references with draining coverings (turf range with Hydrodalle, Betogreen, Hydrojoint range, Aquafil and shell paving) also recognized for their mechanical resistance, let us mention that the offer is completed by a product dedicated to the reservoir roadway (Hydrocyl) and a complete system ensuring infiltration and depollution of hydrocarbons (Clean 4 O').

Also note the Hydrojoint paver which enriches its range with innovative manufacturing based on recycled concrete aggregate: the GBR hydrojoint. This new manufacturing process responds to a major challenge in the development of the circular economy by promoting the use of raw materials from recycling.

Finally, let us point out that all the permeability coefficients K of Alkern draining solutions have been measured and validated in external laboratories.

On the product side, Alkern is further expanding its offering and announces the launch of something new with the Quadro panel. Square in shape (40 x 40 x 10 cm), draining, it can be either grassed or gravelled. Its original design also makes it possible to maximize the grassed area (75%) to increase the greening effect. BC3 load class corresponding to the technical requirements for “concrete products” for draining paving (PT126), Quadro (6,25 per m²) is available in Gray color. Quadro grass tiles are sold from 34 euros per m².
