Alkern 2025 Outdoor Design: 3 New Regional Catalogues for Inspiration

Alkern's leadership in the precast concrete exterior design products market is based on proven expertise and constant creativity to offer the widest range in the segment. This true leitmotif of the Alkern Group is made possible in particular by its 55 manufacturing units spread across France, guaranteeing short supply chains and perfectly aligned local inspiration. The extent of this offer, with more than 2500 references, is thus presented in 3 regional catalogs (North/Center-East, South-East and Grand-Ouest) to be as close as possible to the field with a promotion of regional ranges. While Alkern offers them in paper editions, it should be noted that these solution guides are also available for digital consultation via the website alkern.com.

They will also soon be supplemented by 3 regional editions devoted, this time, to swimming pools, also in print and digital formats. Illustrated by more elaborate stagings thanks to real atmospheres, taken in situ with real products mounted in real spaces, these new 2025 editions claim even more pedagogy. They thus address, for example, the Aldebo effect or the anti-swelling shrinkage of clays, phenomena for which Alkern offers adapted solutions throughout the pages. Let us also mention that Alkern has bet on a wealth of content enhanced by interactivity by relying on digital, like its Signature range which, through a flash code leads to the Instagram account, with the possibility of viewing, among other things, new installation videos.

Suitable for light vehicles, frost-resistant, and non-slip, it also plays the card of possible implementation in curves. Multi-format (11 different modules ranging from 12,5 to 17 cm x 6 cm thick), it is available in Stone Tone and Porphyry Gray.

Elegance at the service of performance

Newhedge paving stone, draining, aged or classic

These new variations of the iconic Alkern paving stone have been designed in a draining version to facilitate the rapid absorption of rainwater by infiltration. By avoiding puddles after rain, these paving stones reduce runoff and the risk of flooding. With a non-slip surface requiring little maintenance, the aged and classic Newhedge draining paving stones, 15 x 15 x 6 cm, are also suitable for light vehicles. They are highly durable thanks to the mass water repellent used during manufacturing, with the key to easy installation thanks to the calibrated joint spacers that allow a spacing of 5 mm to ensure the infiltration of rainwater with joint filling in 1/3 mm or 2/4 mm gravel. They are available in Grey and Ivory colors at a recommended retail price from 39,56 per m², excluding taxes and excluding installation.

For ever more technique

Hydrojoint and Hydrojoint Ocean paving stones

These ranges are complemented by a new product (Hydrojoint 5) to complement the 15 and 30 ranges. This new spacer format is also available for the classic Hydrojoint and the Ocean Hydrojoint. The advantage of this new format is that it allows for many different layouts to be created, making it possible to better delimit spaces on the ground. Available in 3 versions (Classic, GBR – Recycled Concrete Granules – and Ocean) and three joint widths (0,5, 1,5 and 3 cm), the Hydrojoint paving stone is particularly draining. The first two are available in Grey and Quartz White (other colours available on request) and in white for Ocean (made from crushed scallop shell waste, replacing natural aggregates for an aesthetic surface reminiscent of the seaside).

If the Classic and GBR references offer a smooth/washed surface effect and the Ocean version is available in washed, they are sold in 20 x 20 x 8 cm formats (5, 15 or 30 mm spacers) and in 10 x 20 x 8 cm or 20 x 30 x 8 cm (with 30 mm spacers).

Laid in strips on a bed of sand (free of fine or clayey elements) or gravel, they are also suitable for light vehicles and heavy goods vehicles. The Hydrojoint version with 5 and 15 mm spacers is also perfectly suited to the movement of PRM (people with reduced mobility). Easy to maintain, aesthetic, they can also be accompanied by vegetation in the joints (version with 30 mm spacers). Recommended retail price from 31,86 per m², excluding taxes and excluding installation.

Quadro slab

Part of Alkern's O' Range (100% natural and recyclable), the Quadro slab is intended for draining roads and urban development (light vehicle roads, parking areas, soil stabilization, embankments, banks, verges). Square in shape (40 x 40 x 10 cm), draining, the Quadro slab can be grassed or graveled as required. Its original design also maximizes the grassed surface (75%) to increase the greening effect.

Alkern's offering also includes coping stones, borders, Japanese steps, low walls, fountains, etc.

The Novaschiste coping in Anthracite (66 x 33 x 3,5 cm) is appealing both for the modernity of its large format and for its laminated appearance, which adds texture and substance to the pool area. It is available in a flat, straight, internal corner, or external corner version. The recommended retail price for the straight version starts at €33,34.

Very easy to install, the Alkern interlocking edging, here the smooth reference, in Ivory color, ensures the paving stones are held in place and guarantees a perfect finish. It is available in a 50 x 20 cm format and 5 cm thick at a recommended retail price of €2,59 per unit.
