This is what makes them a popular choice over other products such as tarmac, concrete and paving. They have a simple and quick laying process.

How do you use slate chippings?

So we have explained why slate chippings are an excellent landscaping material to use but how do you use them? Slate chippings are versatile, diverse and an ideal material for many different landscaping projects. Here are some of the ways you can use slate chippings:


They are a great choice for creating an easy garden path. The angular stones bed together better than other types of aggregates forming a flatter surface to walk on. Slate chippings are available in both 20mm and 40mm sizes. If you are looking to use slate chippings for pathways, 20mm will be the better choice as they will lay flatter and be smoother to walk on.


Mulch reduces water evaporation and retains nutrients in the soil for plants and other wildlife. Slate is a great substitute for mulch as it is reflective and absorbs heat. This means it keeps the soil cool and retains moisture during the hotter summer months.


Slate chippings are a perfect product to create a low maintenance border. They can help prevent weed growth due to their ability to block sunlight in areas that the weeds are likely to take hold.

Water features

They are resistant to moisture, wear or fading so your water feature will look attractive for a long period of time. Also, slate is fish friendly! So you won’t need to worry about your fish suffering any consequences of having an aesthetically pleasing aggregate!

Pot Toppers

To help your plants retain water in the soil, slate chippings can be used as pot toppers. This will mean they will need to be watered less frequently, not only saving you time but also saving you money on the water bill! The variety of colours that slate chippings are available in means that you are sure to find slate chippings that will complement your colour and shape of pot.

Ground Covering

Slate chippings are low maintenance and cost effective, two attributes that make them perfect for ground cover. Whether using slate chippings for a small or large area, they will take a long time to discolour and is a fairly cheap, affordable decorative aggregate. Using a weed membrane beneath the chippings will enable them to say cleaner for longer.

Planting Beds

Slate chippings will not change the alkaline levels in your soil as they are chemically inert. Therefore they will not damage or kill any lime hating plants! It is also a great planting bed product as it can be easily sprinkled around existing plants.

Paving Slab Decoration

If you have any gaps between your patio slabs, slate chippings are a great attractive way to fill them. As they are available in an array of colours, you will find something to suit most pavings. Slate chippings will complement your existing landscape and the patio slabs and create a contemporary stylish look. Our grey and blue slate chippings will perfectly complement urban paving ranges whilst our plum and green tones will complement more traditional paving.


Slate chippings are a popular choice for driveways as it is affordable, easy to lay and low maintenance. They are particularly a great choice for sloping driveways due to their shape. Their shape allows them to bind together and interlock so when they are driven or walked on by heavy traffic, they do not disperse. If you are looking to use slate chippings for driveways, 40mm slate chippings should be used.

Do I need to lay anything beneath slate chippings?

Regardless of how you plan on using slate chippings in your garden, it is important to dig over the area you are going to overlay. It is then important to cover it in a weed suppressing membrane. Not only will this help to fight against any unwanted weed growth but also stop the chippings from working into the soil. This will mean they will last longer, be more stable and remain clean.
