About Anthracite Granite
Anthracite granite is a robust and durable material formed from the slow cooling of deep-sea magmas. This large grain-size rock is renowned for its resistance to weathering, abrasion, and corrosion, making it an excellent choice for outdoor applications.
Benefits and Features
The anthracite granite kerbstone is characterized by its high density (2,650 kg/m³), significant hardness (6.5 on the Mohs scale), and low water absorption (0.3%). It also boasts impressive mechanical strength, with a compression strength of 152 MPa and bending strength of 15 MPa. Additionally, its high abrasion resistance and class A1 fire rating ensure long-lasting performance.
Product Characteristics
Available in standard dimensions of 10 x 15 x 50 cm, the anthracite granite kerbstone can be customized in size and edge processing to suit specific project requirements. The unpolished surface finish and medium color variation of grey-anthracite add to its aesthetic appeal.
Recommended Uses
- Separation lines between footways and carriageways
- Highlighting access alleys
- Separation marks for parking spaces
- Landscaping material for parks, squares, and backyards
Installation Guidelines
For optimal installation, lay the kerbstones on a concrete underlay (semi-dry screed) supported by gravel. Ensure proper preparation by checking utility routes, cleaning the surface, and excavating a trench approximately 25 cm deep. Lay out a 10 cm layer of gravel, compact it, and then add a 10 cm layer of concrete before embedding the kerbstone. For kerbstones lower than 20 cm in height, installation over a gravel bed is not recommended.
Maintenance Tips
For cleaning and maintenance, use products such as LTP Grimex for pre-installation cleaning and daily aftercare. For color enhancement and sealing, LTP Mattstone or LTP Colour Intensifier are recommended, especially in wet spaces.
Conclusion
Anthracite granite kerbstones offer a perfect blend of durability and aesthetic appeal, ideal for various outdoor applications. With our competitive pricing and reliable services, you can achieve outstanding results for your landscaping projects.
