Product description

Covering ground with natural stone instead of slabs

Basalt Natural Stone is a graded stone for those who want to cover a garden area, walkway or flower bed with natural stone instead of laying slabs. It is spread over the soil, reduces mud and dust, and gives the ground a dark, tidy look. The stone is basalt, a rock of volcanic origin.

Choosing a basalt grade

There are eight grades: fine 5-10 mm up to coarse 10-15 cm. The fine grade suits walkways and pot topping; the coarse grade suits infill and dry creek beds. On ground that people will walk on, fine grains shift less underfoot. Large pieces are used along flower bed edges and in dry creek beds that imitate flowing water. Using two grades in the same garden separates the path from the infill.

Before spreading the stone, level the soil and lay a weed barrier. To keep the stone from spreading sideways, border the edge with an edging strip or curb. If you are looking for colored gravel, see Granite Pebble Stone. For a quote, send us the area, the layer thickness you want and the grade through our contact page, and we will calculate the quantity together.

What is Basalt Natural Stone used for?

  • Ground without slabs

    Covers garden ground and walkways with natural stone without laying slabs.

  • Eight grades

    Fine 5-10 mm to coarse 10-15 cm; the fine grades are for paths, the coarse ones for infill.

  • Anthracite color

    The dark color creates a clear contrast with light-colored stones and green plants.

  • Bag, big bag or bulk

    Bags for small areas, big bags or bulk for large areas; the sales format depends on the grade.

How does Basalt Natural Stone work?

The soil is leveled, a weed barrier is laid and the stone is spread over it in an even layer. The edge is bordered with a curb so the stone does not spill onto the lawn or path. The grade is chosen based on whether people will walk on the surface.

How Basalt Natural Stone differs from standard products

TopicOrdinary productThis product
Bare soilTurns to mud in rain and dust in dry weather. A layer of stone covers the soil.
Slab pavingRequires a subbase, mortar and jointing work. The stone is spread once the soil is leveled and a barrier is laid.

Using and installing Basalt Natural Stone

  1. Measure the area

    Determine the area in m² and the layer thickness you want. With these two figures we calculate the quantity together.

  2. Choose the grade

    Choose a fine grade for surfaces people will walk on, a coarse grade for infill and dry creek beds.

  3. Prepare the ground

    Level the soil, lay a weed barrier and border the edge with a curb.

  4. Spread the stone

    Spread the stone over the barrier in an even layer and level it with a rake.

Care: Remove leaves that fall between the stones with a blower or rake. Top up thin spots over time with stone of the same grade.
