Gravel Calculator

Our Blue Slate Chippings 20mm are a recycled biproduct from the Welsh slate tile industry and feature natural shades of blue with a hint of plum, which deepens when wet.

Ideal for garden pathways where a flatter, more comfortable walking surface is required, and this Slate is also used to finish lawn borders, top raised flower beds, or as a mulch to help promote healthy and moist soil for your garden plants.

Blue Slate Features

As a typically pH neutral stone, Slate Chippings are unlikely to significantly alter the pH of garden soil or water, so these chippings are regularly used in ornamental water features and fishponds, so perfectly safe to use near aquatic life.

Availability

Supplied in bulk bags containing 800kg approx. Or pallets of pre-packed 20kg bags for convenience, you can order the amount you need for your landscaping project.

If you are ‘topping up’ on the slate you already have or looking to extend a decorative garden area by adding more, we advise ordering a sample to confirm that the stone in your garden and our Blue Slate Chippings 20mm match. There will always be some variance between Blue Slate Chippings, from different suppliers, but ours is solely sourced from a quarry in northern Wales so you can be confident our size and colour descriptions are accurate.

Blue Slate Chippings 20mm

Quality and Colour Variance:

Suitable Applications and Versatility:

Blue Slate Chippings 20mm suit almost any landscaping environment, being a popular choice for:

- lawn borders and raised flower beds

- Garden pathways

- As a plant pot topper

- Garden stone rockeries,

- Ornamental water features, fishponds and pondless waterfalls.

20mm Blue Slate features a flattened, angular profile which helps to reduce movement in contrast to a rounded product and offers a clean and contemporary finish to your garden project or landscaping scheme.

Size and Shape:

The industry grading is 20mm but will actually include pieces measuring between 5-30mm due to the natural characteristics of this stone. Please see our Sizing Info

Ordering Information:

For convenience, our Blue Slate chippings 20mm are available for purchase in bulk bags of 800kg, palletised quantities of 20kg poly bags. For our delivered prices, simply enter your delivery postcode into the large orange box, located above and click submit. When topping up existing slate chippings or extending the area by adding more, we always advise ordering a sample first, before making your main purchase to ensure a matching colour and size.

Weed Suppressant:

Complete your Stone Warehouse order with one of our Groundtex - Polypropylene Weed Membranes. This woven polypropylene membrane helps to prevent unwanted weeds from growing through your chosen decorative aggregate, whilst still allowing water permeability to avoid unsightly puddles in wet weather. When added to the basket, along with your bulk bag(s), or pallets of poly bags, we can often send the membrane attached to the pallet and pass on the delivery cost as an order saving.

Frequently Asked Questions

How deep should I lay blue slate?

Blue Slate 20mm should normally be laid at 50mm depth for a good coverage. One of our 800kg bulk bags of blue slate will cover around 10m² when laid at this depth.

Will my slate chippings fade?

Our Welsh sourced Blue Slate Chippings will maintain its deep colour as the climate in the UK isn’t significantly hot enough to cause any significant fading in the sun. If you live in a much hotter and dry climate, you might expect some fading, but this wouldn’t be noticeable for many, many years to come.

Is slate suitable for a driveway?

Slate is a popular choice for driveways due to its affordability, how easy it is to lay and low maintenance, but over time it will crush down and need a top up.
