Anthracite Granite Kerbstone
The Anthracite Granite Kerbstone is a premium choice for outdoor paving, offering a blend of aesthetic appeal and durability. This kerbstone is crafted from granite, an igneous rock formed by the slow cooling of deep-sea magmas, making it exceptionally resilient to environmental factors and heavy traffic.
Advantages and Benefits
Anthracite granite is renowned for its durability against freeze-thaw cycles, acid rain, and strong winds. It is highly resistant to staining agents, including corrosive substances, and can withstand heavy traffic, making it ideal for urban kerbstones and large kerbstones for streets and pedestrian walkways.

Installation Guidelines
For optimal performance, kerbstones should be installed on a concrete underlay or gravel bed. When using a concrete bed, ensure the trench is properly prepared, cleaned, and compacted with gravel before laying the concrete and embedding the kerbstone. For installations over a gravel bed, ensure the trench is marked, dug, and filled with compacted gravel before laying the kerbstone.
Maintenance
To maintain the kerbstone's appearance and longevity, use LTP Mattstone or LTP Colour Intensifier as sealers, and clean with LTP Grimex or LTP Power Stripper for light stains. Regular aftercare can be performed with LTP Grimex.
Conclusion
Anthracite Granite Kerbstone is an excellent choice for enhancing the durability and aesthetic of outdoor spaces. Its robust nature and elegant appearance make it suitable for both public and residential projects.
