Whether you have worked with slate chippings before or want to add blue slate or grey slate chippings to your back garden – it’s only normal to have some questions.

Are slate chippings good for drainage?

Slate chippings can help with drainage when used as a top layer in planters or borders, allowing water to freely drain.

Are slate chippings suitable for driveways?

Slate chippings are not the most suitable for driveways as the slate will easily crumble under the constant pressure of the vehicle. We recommend creating gravel driveways as a better alternative such as 20mm Golden Gravel

What to put under slate chippings?
