Precautions to Avoid Deterioration
- Store Placed
Along Their Natural Bed - Ensure that
stones are stored in alignment with their natural bedding planes to
prevent structural weaknesses. - Proper
Seasoning Before Stone Use - Allow stones
to season properly before use to enhance their durability and
performance. - Number of
Joints Should Be Low - Minimize the
number of joints in stone structures. Using larger stones can help
achieve this, reducing potential weak points. - All Joints Must
Be Filled to Remove Any Cavity - Ensure that
all joints are thoroughly filled to eliminate cavities, which can lead to
water ingress and subsequent damage. - For Important
Buildings, Use Compact Silicious Stones - Opt for
compact silicious stones for critical structures due to their superior
durability and resistance to weathering. - Limestone and
calcareous stone must be avoided. - Sandstone
cemented with silicious binding material may be used.
How to Preserve Stone
- By Coal Tar
- Applying coal
tar can provide a protective barrier against moisture and environmental
pollutants. - Linseed Oil
- Linseed oil is
effective in sealing the stone surface, preventing water penetration and
enhancing its appearance. - Paint
- Painting stone
surfaces can offer an additional layer of protection against weathering
and environmental damage. - Paraffin
- Paraffin wax
can be used to coat stone surfaces, providing a water-resistant barrier. - Solution of
Alum & Soap - A mixture of
alum and soap can be applied to stone surfaces to prevent decay and
enhance durability. - Solution of
Baryta - When decay is
due to calcareous content, a solution of baryta is used for preservation.
Frequently Asked Questions (FAQs)
- Why is it
important to store stones along their natural bed? - Storing stones
along their natural bed ensures structural integrity and prevents
weaknesses that can lead to deterioration. - What is the
purpose of seasoning stones before use? - Seasoning
stones before use allows them to acclimate and enhances their durability,
making them more resistant to environmental factors. - How can
minimizing the number of joints in stone structures help? - Reducing the
number of joints decreases potential weak points, thereby enhancing the
overall strength and durability of the structure. - Why should
limestone and calcareous stones be avoided in important buildings? - Limestone and
calcareous stones are more susceptible to weathering and decay, making
them less suitable for critical structures. - What are the
benefits of using linseed oil for stone preservation? - Linseed oil
seals the stone surface, preventing water penetration and enhancing its
appearance, thereby extending its lifespan.
Conclusion
By following these guidelines and preservation techniques, you can ensure
that stone structures remain durable and aesthetically pleasing for years to
come.
