Basalt Pavers

Basalt pavers are dense volcanic paving stones cut from black basalt — one of the hardest natural stones used in landscaping. With a certified water absorption of just 0.59%, basalt shrugs off freeze-thaw cycles, deicing salts and heavy vehicle traffic, which is why basalt setts have paved snow-belt streets across Europe for generations. Citadel Stone supplies quarry-direct black basalt in every size, thickness and finish — sawn, honed, flamed, bush-hammered and brushed — hand-selected at the quarry and delivered door-to-door across the USA and Canada.

Fundamental Technical Specifications for Basalt Pavers & Tiles

Technical ParameterStandardValueDescription
Density (g/cm³)S.N.S 13933.01–3.06Exceptionally dense — about 15% denser than typical granite (2.6–2.7 g/cm³). Verified across two independently tested batches.
Water Absorption (%)S.N.S 13930.59–0.69Very low absorption across both tested batches, so little water enters the stone to freeze, expand and cause spalling in freeze-thaw climates.
Compressive Strength (N/mm²)Type-level range100–300 (typical)Published range for dense basalt of this type, shown for guidance — not a lot-specific test result. For comparison, ASTM C936 requires about 55 N/mm² of concrete pavers. Lot certificates and an ASTM C170 test report are available on request.
Flexural Strength (N/mm²)S.N.S 13949.04–10.03Roughly 35% higher than the limestones tested in the same lab — resists bending and cracking under vehicle loads.
Abrasion Resistance (mm)S.N.S 11690.87–0.91Böhme abrasion (DIN 52108) — lower is better. About three times more abrasion-resistant than the limestone tested alongside it (2.68 mm), which is why the finish survives heavy traffic and snowplough blades.
Modulus of Rupture (N/mm²)S.N.S 139510.13–11.02The modulus of rupture is exceptionally high, meaning Black Basalt can endure significant stress and pressure without cracking or breaking, perfect for harsh climates and demanding environments.

Undoubtedly the price was the reason that we chose Citadel stone, in addition to the fact that you offer a white limestone that is hard to source. Your products are very good value for money by comparison with other companies. You have helped at every stage of the process and have been quick and reliable in your responses. It was a big risk for us to pay everything up front including shipping and not know the quality. You did make me feel that I could trust you and your company however and we are very happy with the tiles. They appear to have been finished to a very high quality of smoothness and I can't wait to see them once they have been laid. We need to see now how easy they are to fit and maintain, yet you also sealed them before shipment so we think that they will be very durable. Our building project has been delayed for a few months now so it may be sometime before we see them laid, but I promise that I will send photos as soon as we have them down. Thank you so much Kareem and your team, you have done a great job. I am hoping that we can pay for, and receive our second shipment in the not too far future, so that we can finish everything off. Wishing you well. Gemma

I appreciate the quality of product and care for the custom order in packaging each crate to minimize breakage as well as the flexibility with the order to help us make the most of shipping. The timely communications are impressive from the beginning and throughout the process. It's reassuring to have gone through one order to know what the process will be like in the future. I am glad to have had some guidance through the importing process and recommendations for shipping partners to assist. It's incredible to think about the journey the stone traveled to get to our site and I'm grateful to have made it to the next stage of the project relatively smoothly and with from what I can tell

Why are basalt pavers an excellent choice for outdoor landscaping and driveways?

Basalt pavers are highly durable and resistant to wear, making them ideal for outdoor landscaping, pathways, and driveways. Their natural strength allows them to withstand heavy loads and high foot traffic, while their timeless dark tones enhance the aesthetic appeal of outdoor spaces. Many clients comparing black granite pavers choose basalt instead: the same deep-black look with higher density, better slip resistance and a lower cost per square foot, also available as coping, setts and treads.

Basalt handles both extremes, but the cold-climate case is the strongest. With water absorption of just 0.59% (S.N.S 1393), there is very little moisture inside the stone to freeze and expand, which is what cracks and spalls porous pavers through winter. As a silicate volcanic rock, basalt is also chemically unaffected by rock salt and other deicers, unlike limestone and travertine. It performs equally well in desert heat and coastal humidity. In freeze-thaw regions the installation matters as much as the stone: a deep compacted base below frost depth, proper drainage, edge restraints and polymeric-sand joints.

Maintaining basalt pavers is straightforward:

  • Regular cleaning: sweep or rinse with water to remove dirt and debris; use a pH-neutral stone cleaner for deeper cleans.
  • Sealing: generally unnecessary at 0.59% water absorption. For extra stain protection in high-traffic or spill-prone areas, use a breathable penetrating sealer every 3–5 years.
  • Winter care: plough with a rubber-edged blade and top up joint sand each spring; the stone itself is unaffected by deicing salts.
  • Inspect and repair: check for shifting or settlement each spring and re-level individual units promptly.

Basalt pavers offer several design benefits:

  • Timeless Elegance: Their natural dark tones and refined texture suit contemporary and classic styles.
  • Versatility: Perfect for patios, driveways, walkways, and pool surrounds.
  • Eco-Friendly: Made from natural stone, basalt pavers are a sustainable choice for outdoor designs.
    These features make basalt pavers a top choice for creating visually stunning and functional outdoor areas.

Yes, basalt pavers are a cost-effective investment due to their durability, low maintenance requirements, and timeless appeal. While the initial cost may be higher than some alternatives, their long lifespan and resistance to damage reduce the need for frequent repairs or replacements, making them a smart choice for any landscaping project.
