Slate chippings are adaptable and have many uses for outdoor landscaping.

The depth of slate chippings depends on the size of slate chippings and what it's used for.
For example, standard 20mm slate chippings generally should be approximately 4-5cm deep but for driveways this should be 5-6cm. Larger aggregates such as paddlestones are best laid 6cm deep.

Mark out where your slate chippings need to be laid using something like string or rope.
Dig out the area to approximately 4 inches deep. Then, rake the base of the area and compact it using a flattening tool.
At this point you may wish to add a border, keeping the slate neatly contained. For this, you can metal, bricks, wood or stone.
For a driveway, you need to create a sturdy base. Now you have a trench, this needs to be lined with 10cm of crushed stone to create a sturdy surface. Ensure this is compacted with a sledge hammer or place compactor (these can often be hired from a hardware store).
In order to prevent weeds sprouting through your slate, add a weed resistant membrane on top of your stones before you lay your slate. This can be placed on and cut to the shape of your slate area. This can sometimes be an awkward shape, if that's the case, simply overlap cuts of the membrane so there are no gaps.
Your slate chippings can now be shovelled on top of the weed resistant membrane. Make sure you lay a depth of at least 4-5cm and distribute it evenly with a rake.
The best way to clean slate chippings is to create a large sieve and hose down the chippings.
Although slate chipping is low maintenance, there are a few simple ways to ensure your slate chipping areas last for years and years.
What is slate?
Slate is a fine-grained type of metamorphic rock. Slate develops due to the repetition of metamorphic rock layering.
Slate is a highly durable, strong rock, making it a popular choice for construction and outdoor landscaping.
What colour is slate?
Slate is commonly grey in colour, ranging from light to dark. However, slate does vary in colour depending on its mineral composition. More colourful slates are often plum, blue and green.
Can you use slate chippings on a driveway?
Yes, slate chippings can be used on a driveway. Slate chippings are the ideal aggregate for driveways as they are usually very flat, making them easy to walk and drive on.
Slate is a popular choice for driveways because it is affordable, easy to lay and low maintenance.
For sloping driveways, slate chippings are a good choice due to their shape. Slate chippings will interlock together, helping them not to disperse easily and stay in place.
How deep should slate chippings be?
The depth of your slate chippings depends on what you use them for and their size.
Generally, standard 20mm slate chippings should be laid approximately 4-5cm deep. However, specifically for driveways this should be slightly deeper at 5-6cm.
What is calibrated slate?
Calibrated slate means the surface of the slate has been machined to give it an even thickness across all of the slate chippings or tiles in that range.
Uncalibrated slate retains its natural surface and could differ in thickness across a product type.
