Made from metamorphic rock, phyllite slate has a green-grey finish and impressive strength. It also comes backed with some of the most extensive guarantees in the industry

SSQ’s pristine Argentinian phyllite - known worldwide as Riverstone - is hugely sought-after for a number of reasons.

Its unmistakable grey colour, its distinctive phyllitic sheen, its robustness, longevity and comprehensive guarantees are just a few.

Since SSQ first brought it to the UK over 20 years ago, Riverstone has become a highly prized alternative to some of the country’s most popular indigenous slates.

Its mica flakes, and the tiny crystals on its surface, give it an unmistakable silky appearance - a phyllitic sheen - and its attractive grey-green colour instantly distinguishes it from other products on the market.

Comprehensively assessed by independent geologist Barry Hunt, Riverstone was found to exhibit ‘many features that are equivalent or superior’ to three leading indigenous slates.

Riverstone offers the sort of pronounced grain, low water absorption, low calcium carbonate content and pronounced dressed edges as indigenous slate, but with significant advantages.

With a geological age of over 600 million years, it’s even older than much indigenous slate, giving it exceptional strength and weather resistance.

It is available pre-holed - and perhaps most crucially - unlike the vast majority of indigenous slate, it’s readily available in a matter of weeks.

It’s for all these reasons that Riverstone has been specified to replace indigenous slate on roofs around the country - including on grade I and II listed buildings and national landmarks such as Bodmin Jail in Cornwall.

Riverstone, sourced from SSQ’s own San Luis quarry in La Repressa, Argentina, has been extensively tested with impressive results. Assessed to ASTM C406 standard, it was awarded an S1 rating, indicating it will last a minimum of 75 years.

It is for that reason that Riverstone comes backed with some of the most extensive guarantees in the industry. Choose Riverstone and you're covered for 100 years.
