Your size. Your thickness. Your finish, confirmed for this stone.
We cut this stone to the dimensions and thickness your project calls for. Brushed is our signature finish, from a coarse 16 grit to a fine 80, or finer to order. Most of our limestone and basalt can also be supplied sawn, honed or bush-hammered; polished, tumbled and split-face are made on selected stones. Tell us the size, thickness, finish and use, and we’ll confirm what this stone can be made in. Looking for another color? See the full collection.

Citadel Stone presents premium basalt curbstones, the ultimate choice for landscaping professionals, architects, and property owners seeking unmatched durability combined with sophisticated aesthetic appeal. Forged from ancient volcanic lava and refined through millennia of geological processes, our basalt curbstones represent the pinnacle of natural stone performance for both residential and commercial hardscaping projects.
Basalt forms when molten lava rapidly cools at the Earth’s surface, creating an extraordinarily dense, fine-grained igneous rock. This volcanic heritage gives basalt its characteristic deep charcoal to jet-black coloration and exceptional structural integrity. The rapid cooling process creates a tightly interlocked crystalline structure composed primarily of plagioclase feldspar, pyroxene, and magnetite minerals—resulting in a material that rivals granite in compressive strength while offering superior load-bearing capabilities.
With a density of 3.01–3.06 g/cm³ (certified mill test) and a Mohs hardness of 6–7 (published range for basalt, not tested on our stone), basalt curbstones are specified for commercial curbing under heavy traffic; freeze-thaw and de-icing salt resistance have not been tested, so ask us before specifying for either.
At Citadel Stone, we source only premium-grade basalt from carefully selected quarries, ensuring each curbstone meets our rigorous standards for structural integrity, dimensional consistency, and aesthetic quality. Our master masons hand-select blocks and apply precision cutting techniques to deliver products with exceptional tolerances—enabling seamless installation and professional-grade results.

Surface Finishes:
Driveway Edging: Basalt curbstones provide clean definition between driveways and lawns while containing gravel or pavement materials. The superior strength prevents edge degradation from vehicle traffic, while the elegant black coloration creates striking contrast against lighter paving materials.
Garden Borders & Pathway Edging: Create sophisticated transitions between planting beds and walkways. The natural surface texture makes basalt ideal for raised garden edges and stepping stone borders, while the dark tone provides a neutral backdrop that enhances colorful plantings.
Patio Perimeters: Frame outdoor living spaces with architectural precision. Basalt curbstones define entertainment areas while providing structural support for adjacent pavers and preventing material migration.
Street Curbing: Following a tradition dating back to the Roman Empire, basalt remains the premier choice for urban street edging. Its exceptional durability withstands decades of vehicular traffic, snow removal operations, and environmental exposure—significantly reducing long-term maintenance costs compared to concrete alternatives.
Parking Lot Borders: Provide robust containment for asphalt and concrete surfaces while creating clearly defined pedestrian zones. The dark coloration maintains visibility in all lighting conditions.
Public Parks & Plazas: Establish durable boundaries for walkways, water features, and landscape beds in high-traffic public spaces. The timeless aesthetic complements both contemporary and traditional design schemes.
Retaining Walls: Utilize larger curbstone dimensions as facing material for low retaining walls and terraced landscapes. The natural strength provides structural support while creating visually appealing vertical elements.
Water Features: The extremely low water absorption rate makes basalt ideal for fountain surrounds, pond edging, and stream borders. The dark color creates dramatic visual contrast with water while the smooth finish prevents algae accumulation.
Stair Treads & Risers: Incorporate basalt curbstones into outdoor staircases for exceptional durability and a naturally textured tread (wet slip resistance has not been tested). The uniform color creates cohesive design flow from ground-level hardscaping to elevated terraces.
While granite offers excellent durability, basalt provides distinct advantages:
Superior Load-Bearing: Basalt’s lower porosity and denser crystalline structure deliver enhanced weight-bearing capacity—critical for applications supporting vehicular traffic.
Climate Resilience: Basalt’s volcanic origin and minimal water absorption make it exceptionally resistant to freeze-thaw damage, outperforming granite in regions with harsh winter conditions.
Cost-Effectiveness: Generally more affordable than granite while delivering comparable or superior performance in outdoor applications.
Uniform Aesthetics: Basalt’s consistent dark coloration provides predictable visual results, whereas granite’s wider color variation can create matching challenges in large-scale installations.
The advantages of natural basalt over manufactured concrete are substantial:
Longevity: Basalt curbstones routinely last 100+ years with minimal maintenance, while concrete typically requires replacement within 25-30 years.
Maintenance: Zero need for sealing or refinishing; natural patina develops gracefully over time.
Environmental Resilience: Resists the chemical exposure and organic staining that degrade concrete; road-salt (de-icing) resistance has not been tested — ask us before specifying for de-icing salt.
Aesthetic Appreciation: Natural stone increases property values and maintains timeless appeal, while concrete appearances date and deteriorate.
Sustainability: Quarried natural stone with minimal processing requirements versus energy-intensive concrete manufacturing.
Basalt offers critical performance advantages over limestone:
Hardness: Limestone’s lower Mohs rating (3-4) makes it susceptible to surface wear and scratching; basalt’s 6-7 rating ensures lasting surface integrity.
Weather Resistance: Limestone is calcium carbonate-based and vulnerable to acid rain dissolution and freeze damage; basalt is a silicate stone rather than a carbonate, but its freeze-thaw resistance has not been tested — ask us before specifying for freeze-thaw or de-icing salt.
Porosity: Limestone’s higher absorption rate leads to staining, efflorescence, and structural degradation; basalt’s lower absorption (0.59–0.69%, certified mill test) means less moisture uptake and staining.
Our basalt curbstones arrive ready for installation with:
Foundation Preparation: Establish a well-compacted, well-drained crushed stone base (minimum 4-6″ depth) to prevent settling and ensure long-term stability.
Setting Method: Secure curbstones in a concrete footing (minimum 4″ depth, 8″ width) extending below frost line for permanent installations. Alternative dry-set methods suitable for decorative applications with minimal load requirements.
Joint Treatment: Maintain consistent 1/4″ to 1/2″ joints filled with polymeric sand or fine stone dust for aesthetic continuity and structural stability.
Anchoring: For applications adjacent to sidewalks or pavers, consider stainless steel anchor rods with epoxy grout for enhanced lateral support.
