Landscaping Overview

Welsh Slate’s decorative aggregates provide colour, texture and unique practical qualities for the gardener/landscaper, qualities which will not alter the PH values of soils and are safe to use with pond life.

Available in four distinct natural colours – Blue, Plum, Grey and Green – Welsh Slate’s decorative aggregates can be supplied in a variety of graded products. In addition, large feature stones, paving, monoliths, rockery stones and riddled walling stone are also available.

There has been an explosion in the use of Welsh slate in landscaping over the past 20 years, thanks to the popular garden makeover TV programmes which encouraged the use of slate aggregates for a multitude of purposes ranging from water features to mulch.

Welsh Slate has supplied decorative aggregates to many of these TV programmes as well as leading garden designers, the Royal Horticultural Society’s flower shows at Chelsea, Hampton Court and Tatton Park flower shows, and other horticultural and landscaping exhibitions as well as a multitude of garden centres and DIY stores.

Welsh Slate’s aggregates are regarded as very eco-friendly as they are a by-product of the roofing production and are entirely made in the UK.

Typical applications are:

  • Flower/shrub beds and weed suppression
  • Garden and municipal footpaths
  • Cycle/sports tracks
  • Pond linings
  • Hard standing areas for cars and caravans
