Every finish. Every size. Every thickness.
Brushed is our signature finish — available in any grit from a coarse 24 for maximum grip to a fine 120 for a soft, velvety sheen. We also cut sawn, honed, tumbled, split-face, and bush-hammered, in any dimension and thickness your project calls for. Tell us your specification and we cut to it.
Ships by pallet or container to any US state · Lead time quoted per order
Suitability varies with size, thickness, finish, and substrate. Tell us your application when you request a quote and we will confirm the right specification for it.
Bedding: full-bed sand and cement mix or a flexible adhesive appropriate to the substrate.
Joints: from 3 mm for sawn tiles; wider for split-face setts and cobbles.
Sealing: a quality impregnating sealer is recommended for limestone and shellstone; basalt and granite typically need none.
Cutting: wet saw with a diamond blade.
Installation requirements differ by stone and format — a product-specific method note is included with every quote, and our team is available for your installer’s technical questions.
Pricing improves materially with quantity: pallet rates beat per-piece pricing, and full-container rates beat both. Every quote is calculated quarry-direct, with no distributor margin in between.
Distributors, stone yards, and retailers: our Trade & Wholesale Program covers container-load pricing, recurring supply schedules, and private-label production.
Orders ship by pallet or full container to any US state, with kerbside delivery to the nearest safe access point. Lead times depend on stone, finish, and quantity, and are confirmed with your quote. Samples reach any US address within five working days.
Every crate is inspected and photographed before it leaves the yard — if anything is wrong on arrival, contact us and we will make it right.
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 averaging 2.9 g/cmÂł and a Mohs hardness rating of 6-7, basalt curbstones deliver commercial-grade performance that withstands decades of heavy traffic, extreme weather fluctuations, and environmental stresses that would compromise lesser materials.
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.

Custom Dimensions: Available upon request for specialized applications
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 anti-slip properties make 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 slip resistance. 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: Immune to road salt damage, chemical exposure, and organic staining that degrades concrete.
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’s silicate composition provides superior weather resistance.
Porosity: Limestone’s higher absorption rate leads to staining, efflorescence, and structural degradation; basalt’s minimal porosity prevents moisture-related damage.
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.
