Why Choose Lime Pointing?

Lime pointing is typically employed on older buildings of historical significance, conservation areas, Grade I and II listings, or those constructed prior to the 1940s. This technique is essential when the existing mortar has deteriorated or has been repointed with cement, which compromises the breathability of structures built with lime mortar substrates. Cement traps moisture between the layers of cement and lime, leading to the gradual deterioration of the brickwork or stonework, as it cannot breathe. This entrapment can result in the erosion of the bricks' faces or cause spalling on the surfaces of the brick or stonework.

Survey, Mortar Analysis, and Documentation

We conduct comprehensive on-site surveys to assess your project and recommend the most suitable types of lime tailored to your specific requirements. We are committed to matching the lime pointing to the original mortar's vapour permeability, strength  and can utilise different coloured sands and special dyes to customise the colour or match it to the existing substrate. Our services encompass a wide variety of pointing types, allowing you to choose one that complements the existing appearance or is best suited for the prevailing weather conditions. We typically focus on Grade I and II listed buildings, where preserving the authenticity of the original structure is of utmost importance. With extensive experience in managing Listed Building Consent and working closely with conservation officers, we are  well-equipped to assist you throughout the entire process. We provide guidance at every stage and handle the submission of any necessary documentation on your behalf.

Flexible and Self-Healing

The self-healing property of lime pointing derives from its ability to absorb moisture and carbon dioxide from the environment, triggering a chemical reaction that facilitates the reformation of calcium carbonate. As this occurs, minor cracks and voids within the mortar can be filled, restoring its structural integrity and preventing further deterioration.

This characteristic is particularly beneficial for older buildings and historic masonry, where movement and environmental factors can cause wear over time. By allowing slight movements within the structure without cracking, lime pointing effectively maintains the bond between individual units, minimising the risk of water infiltration that can lead to serious structural problems.

Vapour Permeable and aesthetic

The versatility of lime pointing not only enhances its aesthetic appeal but also allows it to blend seamlessly with various architectural styles. It provides a breathable joint that promotes moisture management, ensuring trapped moisture can escape and reducing the likelihood of damage from dampness or freeze-thaw cycles.

Summary

Lime pointing is a vital protective measure for masonry, showcasing the remarkable self-healing capabilities of lime-based materials. This makes it an excellent choice for conservation efforts, ensuring that the authenticity and structural integrity of historic buildings are upheld while also accommodating necessary structural repairs and brick or stone replacements.
