SSQ Del Carmen Ultra Slate

SSQ Del Carmen Ultra Blue Black Slate is a traditional, true geological blue-black riven slate with a distinctive texture, noted for its longitudinal grain.

The Del Carmen quarry is one of the largest in Spain, situated in the Cabrera mountains, an area featuring geomorphic conditions favourable to the formation of uninterrupted seams of high quality slate.

The SSQ Del Carmen Ultra slate has been tested to international standards, including Marque Nationale Norme Française. This norm is widely known as the highest classification worldwide and the testing is carried out at the quarry on a yearly basis by the Laboratoire National d’ Essais. It has also been tested according to the BS EN 12326 achieving outstanding results.

SSQ Del Carmen Ultra is supplied with a written guarantee of 100 years.

Test certificates, an independent geological report and samples are available from SSQ on request.

As a testament to the consistent high quality of SSQ Del Carmen Ultra Blue Black slate, the slate has previously been accepted by English Heritage and Historic Scotland for the refurbishment of listed buildings.

SSQ Del Carmen is also approved by Snowdonia National Park as an alternative to indigenous slate.
