The Importance of Traditional Lime Mortar Pointing for Aberdeen's Historic Buildings
 

In Aberdeen, many historic granite and sandstone structures were originally constructed using lime mortar. This traditional material offers flexibility and breathability, essential for the longevity of such buildings. However, the introduction of Portland cement in the early 19th century led to its widespread use, often replacing lime mortar. While Portland cement sets rapidly and achieves high compressive strength, it lacks the flexibility and permeability of lime mortar, making it less compatible with older masonry structures
 

Issues Arising from Incompatible Mortar Use
 

Utilizing cement-based mortars on buildings initially constructed with lime mortar can lead to several problems:​

• Moisture Trapping: Cement's low permeability can trap moisture within walls, leading to damp issues and potential decay. ​

• Structural Stress: The rigidity of cement doesn't accommodate the natural movements of historic structures, resulting in cracks and damage to masonry. 

• Aesthetic Discrepancies: Cement mortars can visually clash with original lime mortars, affecting the building's historic appearance.

Advantages of Traditional Lime Mortar
 

Reverting to or maintaining the use of lime mortar in repointing offers numerous benefits:​

• Breathability: Lime mortar allows moisture to evaporate, reducing the risk of dampness and associated issues. ​

• Flexibility: Its accommodating nature supports the subtle movements of older buildings, preserving structural integrity. ​p

• Compatibility: Lime mortar aligns with the physical properties of traditional masonry, ensuring a harmonious and durable bond. ​
