New products 2017 Ghisa slab
In 2017, the Métal range becomes Ghisa and still features a most refined hammered effect in the 'industrial spirit' trend. Ghisa slabs are available in two thicknesses and 3 shades: 3,5 cm in Metal Grey or 2,5 cm in Grey or Stone tone.

With dimensions of 75 x 45 cm, Ghisa slabs will elegantly dress terraces, pool surrounds or garden paths.

Abbaye pool coping
This 4e coping model completes the Abbaye range. With its rectilinear format (60 x 30 cm) and its thickness of 10 cm, the Abbaye pool coping is perfectly suited to finishing pool edges and is particularly intended for those of lap pools.

Its mineral, aged-stone look and very current dimensions give pools aesthetics and authenticity.

Novadal presents its new large-format slab
Another brand of the Alkern Group, Novadal stands out for its expertise in manufacturing paving and street furniture in architectural concrete. Novadal paving solutions are perfectly suited to landscaping private gardens (terrace, pool surround, etc.) and some can even be used for public squares (under particular conditions).

The Novadal credo? Through quality and innovation, to offer aesthetic solutions in slabs as well as copings, available in a multitude of finishes for total customer satisfaction.

Graffi slab
The large-format Graffi slab (80 x 40 x 3,5 cm) surprises with its entirely original structure: its raw concrete look, delicately combed, dresses terraces and pool surrounds with a modern touch.

Available in Grey, the Graffi slab suits all laying styles (on sand and lean screed): in strips, with crossed or staggered joints, or even in opus for an unprecedented graphic effect.

Nextéria: 4 exclusive new products
A new brand of the Alkern Group, Nextéria designs pressed concrete solutions for outdoor landscaping with a wide offer of pavers, curbs, slabs and pillars in multiple shades, looks and formats.

Whether around older or resolutely contemporary homes, everyone will find their style and their answer for successful outdoor landscaping.

Gironde slab
Thanks to its thickness of 6,3 cm, the Gironde slab allows multiple applications on terraces, pedestrian paths or even driveways. Its multiple formats (30 x 30 cm - 30 x 15 cm - 30 x 45 cm) and its three natural shades (Shaded Grey, Shaded Ashen Vermilion or Sand) adapt to all exterior architecture projects.

The Gironde slab also offers a wide choice of laying on sand in strips or in opus with free patterns. Finally, its concrete look, at the forefront of outdoor trends, will bring an elegant touch of modernity to all exteriors.

Airial slab
With a smooth look, the Airial slab gives paths and gardens a resolutely contemporary look. The range is available in many formats: 40 x 40 cm or 50 x 50 cm for 4,5 cm thickness - 50 x 50 cm for 5,3 cm thickness - 60 x 40 cm for 5 cm thickness. Available in soft shades (Porphyry Grey, Ivory, Granite Grey or Sand, depending on the models), the Airial slab will brilliantly dress any type of exterior.

Note the arrival for 2017 of a new thickness (5,3 cm) under classification T11 (pedestal laying for collective or public use).

As well as being easy and quick to install, pedestal laying allows optimized water drainage under the paving and makes it easier to run electrical conduits or pipes under the terrace. Finally, another significant advantage: by limiting the use of additional materials such as joints, sand or glue, it is a technique that significantly reduces laying cost and time...

Factory-treated exposed aggregate slab
These new factory-treated exposed aggregate slabs offer exemplary durability. Almost impermeable thanks to their water-repellent and oil-repellent treatment, these slabs offer exceptional resistance to moisture, frost and crumbling, not to mention a retarding effect on the growth of moss and other fungi.

In a square format (40 x 40 x 3,7 cm), these slabs with an exposed aggregate look are available in 3 colors: White, black on a white background, White, pink on a white background and White, green on a white background.

Split pillar
And since outdoor landscaping also concerns fences and gate pillars, Nextéria also offers the Split pillar. With its square format (30 x 30 x 18 cm) and its sand color, the Split pillar suits any project and will certainly give charm and character to property entrances.
