Slate is formed naturally from a combination of minerals and clay through time, compression and heat. This forms a type of rock that is then mined and has been used in construction for centuries, thanks to its natural waterproofing and toughness. Another benefit of slate is that the way that it’s formed paves way to a wide variation of slate chipping colours, making it attractive when used as a feature.
So how are slate chippings made? Because slate is used for tiling, it must be cut to a standard size and shape. In this process, offcuts and chips happen often, creating a lot of waste material. Fortunately, these chippings can be used for a whole host of new projects.
We’re going to answer a few questions about how slate chippings can be practically used, how effective they are for drainage, and how chippings can be handy for other landscaping projects.
Slate allows for water run-off because it’s moisture proof. However, it’s not usually used as a sub-base because slate is more brittle, crumbling under heavy weights and pressure. That’s why aggregates such as gravel and shingle are better suited to this.
Slate is better suited as a top layer when used as a bedding layer or path. And while slate chippings can actively reduce weed growth, it’s possible that some weeds may grow through. For this reason, a weed proof membrane can be used to place as a layer before adding the chippings. Fix your membrane with pegs, making holes where you intend to put flowers and plants. Plant your flowers or plants in place, then spread the chippings out around them.
Slate chippings work well as a mulch to cover soil. Mulch is a loose covering of organic material, often a mixture of bark, wood chips, food scraps and other compostable material that can aid plant growth. The nutrients are released into the soil as the organic material decomposes. Slate chippings can be helpful to this process, as they help to drain moisture into the mix.
You can cover quite a broad area of your garden with slate chippings with a large bag. For example, an 800kg slate chippings bulk bag can roughly give you coverage of around 4m2 at a depth of approximately 3-4cm.
Because of its broad range of uses, slate chippings can be a great way to solve lots of little problems around the garden. Whether you need a bulk bag, or trade bag of slate chippings for your landscaping project, we can help you. Order online from Travis Perkins for home delivery.
