Lime Mortar Pointing

An introduction to Lime Mortar

Traditional mass-masonry wall construction (which includes most walls built before 1919) works on the basis that moisture entering a wall is able to escape as water and water vapour as easily as possible. Conserv Lime mortar pointing can readily handle the transmission of water and water vapour between the inside and outside of a masonry wall, owing to the complex interconnected pore structure of masonry.

The use of cement mortars is widely recognised as being detrimental to such buildings and structures as they can drastically alter the way in which a wall handles water and water vapour. Cement mortars tend to have a consistent and ‘closed’ pore structure that traps water rather than allowing the building to breathe (not necessarily a problem in modern cavity wall construction). Any trapped moisture will expand if subjected to freezing conditions, and mortars may ultimately fail, often causing damage to the surrounding masonry in the process. (Conserv Lime Mortar)

Masonry walls need to be maintained and repaired, just as roofs and rainwater goods do. Where walls are solid, without a cavity, keeping them in good repair is necessary for the interior to remain functional and dry. Pointing is the most common repair, and often one of the most poorly executed.

What is lime mortar?

Lime mortar is an old-fashioned pointing material that was widely used in construction until the early 1900s. Many of the older Edwardian & Victorian buildings in Cheshire, Staffordshire, Wirral and Derbyshire need lime mortar pointing for specific brick repair and restoration. Using the wrong kind of mortar in a brickwork restoration or repair project can cause a lot of damage and aesthetically can look a real mess.

Lime mortar is not only a traditional alternative, it’s also a green pointing material. That’s why it’s a popular choice for conservation and restoration work and building extensions that need to match an older building nearby.

Why do older buildings need lime mortar?

Lime mortar helps older buildings and houses to avoid damp and maintain the quality of the building by being more breathable i.e., letting moisture escape quicker. Lime mortar is a different option from more modern cement and has numerous considerations when using as colour is also a factor besides the additions cost of the material and the additional time installing it.
