Contact usProven performance across Europe
Riverstone’s versatility is showcased in landmark European projects across various climates and creative Europe architectural styles for cladding and flooring. In Oslo, it brings cohesion to interior and exterior walls and flooring, withstanding the region’s harsh Nordic climate, while in Gothenburg, Sweden a stunning hotel owes its contemporary style to Riverstone, which was specifically chosen for the external cladding to complement the design of surrounding buildings.
In Denmark, our brushed Riverstone slate brings calm, clarity and durability to sleek medical interiors and modern members’ clubs, proving ideal where performance and aesthetic precision align. And in Berlin, Germany, Riverstone architectural stone was specified for a museum’s flooring, the design calling for a ‘grey natural stone’ and the same material to be used inside the building, for the central courtyard and for the paths leading to the cellar-wall exhibits.

Testimonials
The choice of SSQ Del Carmen was made easier after confirmation that it had gained approval for use in the Welsh National Parks as an alternative to indigenous materials. We were also pleased with the level of technical, design and on-site support we received from SSQ.
The Hafod Renewal Office
Testimonials
With so many ‘interested parties’ the local planners set their minds on a natural slate roof at a very early stage of the project and, from this starting point, we needed something that would satisfy a number of technical and aesthetic requirements – SSQ Domiz blue-grey, was the one chosen for use to compliment the local ‘Shere Green’ colour.

Everyone liked Sarria: the client was delighted with its appearance and its consistency made it easy to cut and lay.
Gary Lambert, Complete Roofing Contractors
Testimonials
With the roofs being such a visible feature, the choice of roofing slate was a significant decision. We involved the roofing contractor at an early stage in the selection process and they recommended SSQ’s Del Carmen Blue-black slates. Although it’s not an indigenous slate, it is an excellent match for the originals and, having used Spanish slate on other projects, we know the quality is there.
Richard Thorpe, Ridge and Partners LLP
Testimonials
The quality and strength were there, the colour was similar to indigenous Welsh slate and its ‘traditional’ look was in keeping with the surrounding community. In fact, as I had used it on my own Edwardian house, I knew it was a good slate!
Julian Bohling, OSP Architecture
Testimonials
We put forward Riverstone as a cost-effective, yet high quality alternative to Welsh Slate, and it was accepted on that basis. The refurbishment work has now been completed and both the owners and ourselves are very happy with the result.

Working in a conservation area brings a special responsibility. SSQ Riverstone slate fits perfectly, its tone and texture blending seamlessly with its surroundings.
Joan Kinane, Architect
Testimonials
We specified SSQ First Domiz Blue-grey roofing slate for both technical and aesthetic reasons:its strength and quality gives the performance needed and its cold, hard, colour provides a dramatic foil to the rich warmth of the western red cedar walls.

The choice of slates was made easier due to the quality of product you provide and the support of Gary Firth throughout the process – which I much appreciate. Gary is a good ambassador for your company.

SSQ Rocaber Blue-grey slate was actually chosen at the initial design-concept stage. A natural slate roof was in keeping with the traditional local architecture.
