Products Description
Basalt paving slabs are a solid, long-lasting choice for outdoor spaces. If you're looking for a dark stone with a clean finish and natural strength, basalt is worth a closer look.
These slabs are made from volcanic rock-formed when lava cools quickly. That gives basalt its dense structure and fine texture. It's naturally tough and performs well in all kinds of weather.

Why Choose Basalt Slabs?
1. Strong and reliable – High compressive strength and low porosity
2. Weatherproof – Handles sun, rain, and frost without cracking
3. Slip-resistant – Especially with flamed or bush-hammered finishes
4. Low maintenance – Easy to clean and doesn't fade easily
5. Stylish look – The deep grey color suits both modern and rustic designs

Application
- Modern patios: With a honed or flamed finish, basalt gives a clean and sleek look for outdoor lounges.
- Garden paths: Bush-hammered or split surfaces provide grip and contrast beautifully with greenery.
- Driveways: Basalt handles weight well-just make sure the sub-base is done properly.
- Urban spaces: Public plazas, walkways, and steps often use basalt for its toughness and clean aesthetic.
- Pool areas: Sealed basalt offers both beauty and function, but make sure the surface isn't polished-go for anti-slip textures.
Installation & Care Tips

Always lay basalt slabs on a solid, level base-usually compacted gravel and a sand-cement screed.
Leave slight gaps between slabs for jointing (sand or mortar).
Seal the surface before or after installation, depending on the finish.
For cleaning, just use water and a soft brush. Avoid strong acids or bleach.
Pro tip: Avoid using polished basalt outdoors-it gets slippery when wet.

Tips
I always suggest sealing basalt if it's going in a high-traffic or wet area. It keeps the color rich and helps prevent stains. And if you're laying it outdoors, make sure the base is solid-this stone is heavy and deserves a good foundation.
