The Welsh Plumb Slate Aggregate is a purple slate used commonly for domestic landscaping across the UK. UK slate supplies this popular decorative and weather-resistant material in 950kg with variable aggregate sizes of 10, 20 and 40mm. Our A1 and T1 certifications apply to this purple slate aggregate, which has also been thoroughly tested to meet BSEN12326-1:3044 standards.

What is Welsh Plumb Purple Slate Aggregate?

Our Welsh Plum Slate Aggregate is ideal for an extensive range of domestic landscaping projects and commercial developments.

This purple slate is quarried in North Wales from Penrhyn Quarry, a plum heather colour with tones of blue and green running through, making a lovely subtle backdrop to plant or garden features. The 20mm size is mainly used for pathways and driveways as it is flatter than the 40mm, making walking and driving more accessible. For a more textured finish, try the 40mm Welsh Plum.

Why Choose Slate Aggregate?

Decorative slate aggregate has several benefits. It is low maintenance and helps prevent weed growth. It is versatile and can be used for paths, driveways, edging, water features, rockeries, decorative borders, etc.

It is also easy to install and a popular choice over tarmac, concrete and paving as they’re much simpler to lay. In addition, decorative aggregates require much less maintenance than other garden landscaping products and can save time. They are also cheaper than many other landscaping products.

Welsh Plumb Purple Slate for Landscaping

Please remember that this is a naturally quarried slate and that our bagging process will result in the aggregate being covered in dust. This may result in the initial appearance being different to product images but don’t panic; this can be easily removed by using a hose or by simply allowing natural rainfall to do this once the product is laid.

To estimate your requirements, we work on a basic calculation – 1mtr3 (cubic metre) = 1.7 tonne.

For example – 6mtr long x 5mtr wide at 75mm (0.075mtr) deep = 2.25mtr3 = 3.825 tonne = 4 bags

All our deliveries are made on a tail lift vehicle with a pump truck to the nearest point of access – the driver requires a flat paved area to offload – concrete, tarmac, block paving etc. We cannot offload onto gravel, grass or hardcore. We can also offer Bulk Tipped loads. Contact us if you have any questions about this popular product.
