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.
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.
