Black Basalt Split Cube Cobblestone

Products/Project Information

Basalt paving stones are a type of stone product made from natural basalt, cut into regular small blocks for ground paving. They combine practicality and aesthetics, and are commonly used in plazas, pedestrian streets, courtyards, parks, and other similar locations. The following are their core characteristics and key engineering features:

1. Material Properties

High Hardness and Wear Resistance: Basalt has a compressive strength ≥120 MPa and wear resistance 1.5–2 times that of ordinary granite, capable of withstanding occasional vehicle traffic.

Low Water Absorption: 0.15%–0.3%, resistant to freeze-thaw cycles (-35℃, 50 cycles) without cracking, suitable for cold northern regions.

Natural Anti-slip: After flamed or bush-hammered treatment, the surface friction coefficient (BPN) ≥65, reducing the risk of slipping on rainy days.

2. Specifications and Finishes

Standard sizes: 100×100 mm, 150×150 mm, 200×200 mm, thickness 30 mm, 40 mm, 50 mm; custom shapes such as 80×80 mm or 300×300 mm are also available.

Six commonly used surfaces: smooth, flamed, lychee-patterned, pineapple-patterned, brushed, and natural; the pineapple-patterned surface, with its 3–5 mm unevenness, offers the best anti-slip effect.
