Gohare Bush-hammered Limestone
Introduction to Gohare Bush-hammered Limestone
Gohare Bush-hammered Limestone is a high-performance textured surface finish of Gohare Limestone, developed for architectural and construction projects that require strong slip resistance, structural durability, and a visually textured stone surface. Extracted from the well-known Gohare quarries in Khorramabad, Lorestan Province (western Iran), this natural limestone has been supplied to major construction and façade projects for more than 75 years.
When processed as Gohare Bush-hammered Limestone, the stone transforms from a smooth surface into a robust, anti-slip material suitable for demanding environments. The finish enhances surface friction while preserving the natural strength and durability of limestone.
Geological and Mechanical Properties of Gohare Limestone
The base material behind Gohare Bush-hammered Limestone is a dense, fine-grained limestone known for its reliable physical and mechanical performance. Its uniform structure provides consistent quality and long-term durability in architectural applications.
Technical Specifications (Average)
| Property | Measurement |
| Water Absorption | 0.3% – 0.5% |
| Compressive Strength | 1000 – 1500 MPa |
| Specific Weight | 2.5 – 2.8 g/cm³ |
| Porosity | 2.5% – 3% |
With density typically between 2550 and 2650 kg/m³, Gohare Limestone provides excellent structural stability for façade systems, paving applications, and architectural components. For exterior installations, waterproof sealing is recommended to improve resistance against environmental exposure, particularly in cold climates with freeze-thaw cycles.
Bush-hammered Surface Processing
The bush-hammered finish is a mechanical surface treatment that creates a rough, evenly textured stone surface with high slip resistance.
During production:
- Special bush-hammer heads with multiple metal points strike the stone surface.
- The surface layer is chipped uniformly across the stone face.
- A consistent rough texture with enhanced grip is created.
Compared to sandblasted finishes, Gohare Bush-hammered Limestone produces a deeper and more pronounced surface texture. The stone becomes visibly rougher, more durable, and highly resistant to slipping, making it suitable for safety-focused architectural environments.
Applications of Gohare Bush-hammered Limestone
Due to its anti-slip characteristics and durable surface structure, Gohare Bush-hammered Limestone is widely used in outdoor and high-traffic areas.
- Public plazas and open spaces
- Pavements and pedestrian walkways
- Rain-prone or snowy regions
- Outdoor staircases
- Commercial and public circulation areas
- Landscape and urban design projects
The textured structure improves friction under wet conditions while maintaining the stone’s structural integrity and architectural appearance.
Visual and Functional Characteristics
Gohare Bush-hammered Limestone combines technical performance with architectural identity. The surface treatment creates a matte and non-reflective finish that reduces glare and enhances safety.
- Uniform rough texture distribution
- Matte, non-reflective surface
- Reduced glare under direct sunlight
- Improved slip resistance
- High durability under heavy foot traffic
The natural fossil patterns within Gohare Limestone remain subtly visible after bush-hammering, but the treatment emphasizes surface texture rather than visual pattern. This creates a balanced architectural appearance suitable for modern and functional design projects.
Durability and Environmental Performance
Gohare Bush-hammered Limestone performs well in outdoor environments due to its dense structure and abrasion resistance. The material maintains its surface quality under temperature changes, heavy use, and environmental stress. However, like most limestone products, it is not recommended for environments with constant heavy water exposure such as commercial kitchen flooring or permanently wet industrial surfaces.
Proper installation methods, sealing, and maintenance planning help maximize long-term performance and appearance.
