Brazilian Black Slate Paving Slabs 600 x 300 x 15mm, these uber cool slabs will give you that premium slate look. They are of course machined on the underside to create a very consistent 15mm (nominal) depth for super fast installation, these slabs have crisp sawn sides with a gently textured riven surface. Very premium and will be sure to transform any living space.

The 15mm  Benefit?

Brazilian slate is very strong - don't let the thickness at 15mm worry you. As long as you install these slate slabs on a full bed they are rock solid - don't cut corners by using a "dot & dab" approach.  Get the look without the price tag. Aesthetically they share all the same attributes as the slabs in the same range that are 20mm. The installation method for both are the same - full bed of mortar on a compacted solid surface. 

As the thickness is 15mm we employ a smaller format slab so that it maintains the same strength as a larger 20mm slab.

In a nutshell if the 600 x 300 format slab works in your scheme, the 15mm format will work out to be a very cost effective option.

Other Benefits 

What we like about these slabs is how versatile they are, making them so easy to use in almost any scheme whether it's modern or traditional. They ooze sophistication without being "shouty" - classy and understated with a premium feel.

The colour palette ranges from lighter to darker shades of black and grey, broken up with natural markings that make this authentically a natural stone. 

Super easy to keep clean - once sealed grub and grime literally fall away, simply push off any excess water and your are ready to entertain friends and family. This is the true essence of enjoying the outdoor space and sharing it with loved ones.
