Can United Kingdom's Blue Lias Limestone be used exterior applications in cold climates?
The Blue Lias Limestone from the United Kingdom can be used in exterior applications in cold climates but with caution. Blue Lias Limestone has moderate strength and durability, which makes it suitable for certain outdoor uses. However, it is important to consider a few factors before using it in cold climates.
1. Freeze-thaw resistance: One concern in cold climates is the freeze-thaw cycle, where water trapped within the stone can freeze and expand, causing cracking or spalling. Blue Lias Limestone has varying levels of resistance to freeze-thaw cycles, so it is essential to select a grade of the stone that has been tested and proven to have good freeze-thaw resistance.
2. Porosity: Limestone is naturally porous, which means it can absorb water. In cold climates, the absorbed water can freeze within the stone, leading to damage. To mitigate this, it is important to choose Blue Lias Limestone with low porosity or apply a suitable sealer to reduce water absorption.
3. Finishing and maintenance: The finish applied to Blue Lias Limestone can also affect its suitability for cold climates. Certain finishes, like honed or polished surfaces, may be more prone to damage in freezing temperatures compared to rough or textured finishes. Additionally, regular maintenance, such as sealing and cleaning, should be performed to preserve the stones integrity.
Overall, while Blue Lias Limestone can be used in exterior applications in cold climates, proper selection, installation, and maintenance are crucial to ensure its longevity and performance. Consulting with a professional stone supplier or contractor familiar with local climate conditions would be advisable to make an informed decision.
