Product Details

Both practical and aesthetically appealing, Welsh Slate decorative aggregates are produced from stone formed deep within the Welsh national park some 450 million years ago. Pure Welsh water, natural weathering and mineral processes has slowly transformed the stone, lending it unique technical properties.

The grey slate decorative aggregate is a rich coloured slate, in particular when wet. The grey slate comes from the Ffestiniog Quarry, in the North Welsh peninsular in Wales and the quarry has been worked since the mid 19th Century. The stone was formed during the Ordovician period 450 million year ago, is hard wearing and colour fast.

Slate decorative aggregates are very versatile and can be used in numerous locations including paths, driveways and for landscaping. They are also widely used for decorative borders where plants, shrubs and small trees are planted.

Borders are usually very prone to weeds and much time in the garden is often spent weeding to ensure that plants grown in them are not suffocated by unwanted growth. Using slate decorative aggregates can save you a lot of time by preventing sunlight reaching unplanted areas where weeds are more likely to take hold.

Weed prevention is not the only benefit of using slate decorative aggregates. Using slate decorative aggregates improve the quality of your soil - they also help the soil retain moisture during hot spells where watering is needed more often. Not only do the benefits of slate decorative aggregates make them a great choice for gardeners, but for anyone wanting to make a beautiful, modern and colourful statement in their garden.
