Slate is ideal for paving as it is extremely resistant to green growth and slimes so is not slippery in wet weather and retains its appearance and colour over a long time. It is extremely strong, completely water proof and ideal for patios, paths and wall coping.
The paving may also be used internally where it is recommended to use a special slate sealer. This confers a gloss finish that enhances the lustre of the slate, its colour and repels dust.
The standard slab is 20 mm thickness either “calibrated” or “riven – riven”.
The “calibrated” slab is machined on the rear face to give a flat surface for ease of laying.
The “riven- riven” slab is as split and is more variable in thickness but slightly cheaper.
Sizes are: 500 x 500 mm, 400 x 400 mm, 500 x 250 mm and 250 x 250 mm.
Thicker slabs can be supplied to special order but are considerably more expensive.
Tiles are also available, again with a riven finish and calibrated to 12 mm thickness. These are suitable for light duty external use and internal flooring.
Sizes are: 300 x 300 mm, 300 x 400 mm, 300 x 600 mm, 200 x 200 mm, 200 x 400 mm, 400 x 400 mm, 400 x 600 mm, 250 x 250 mm and 250 x 500 and 500 x 500 mm.
