Charcoal Granite Gravel 20mm is a stylishly smoky grey volcanic aggregate that darkens beautifully to a deep, jet-black colour when wet. It is extremely durable and resistant to moss growth making it the perfect decorative material for dressing garden paths and general decorative landscaping.

Also known as Black Basalt or Black Granite, this aggregate is mostly angular in shape meaning it interlocks naturally and stays in place when walked or driven on.

The actual size ranges between 8-25mm, and it is best laid 3-4 cm deep.

Charcoal Granite Gravel Uses

Black is a very bold colour to feature in a design and when used in the perfect setting with contrasting colours it can instantly add a stylish designer look to any style of garden. For the best results, Charcoal Granite can be used for:

  • Creating eye-catching paths, patios and driveways that are easy to lay and will look stunning for years.

  • Forming a stylish backdrop for plants, flowers and shrubs in rockeries, planting beds or borders.

  • This contemporary volcanic gravel reflects light beautifully, creating a shimmering effect that is only amplified by the company of flowing water; darkening the stone to a shiny jet-black hue. Perfect for water features or ponds.

  • Contrasting against lighter, brighter aggregates such as Polar White to make a statement or distinguish one garden zone from another.

  • An ideal alternative to mulch, Charcoal Granite absorbs moisture and drains water efficiently, allowing plants to thrive whilst suppressing unwanted weeds.

  • Residential and commercial landscaping.

Weeds are naturally suppressed by gravel, but for added protection you can add a Weed Resistant Membrane before you lay your gravel and save yourself hours of weeding!
