Repointing is an important process that helps restore the structural integrity of the external brickwork by refreshing the damaged mortar joints in the property. While property owners focus on the visible repairs, the most technical aspect of repointing is ensuring proper mortar matching. With the correct mortar composition, colour, and texture, long-term durability and maintained structural integrity can be ensured after the repointing service is completed.
In most of the professional repointing projects, mortar matching is not guesswork. It is rather a skilled process done by the professionals. Hence, for repointing in London, contact the professionals.
Understanding the role of mortar in brickwork
Mortar is a bonding agent that holds the bricks together and allows the structure to move naturally. Mortar is a soft material and is softer than the brick. The moisture content and the minor structural shifts in the brickwork are absorbed by the mortar. This helps to prevent cracks in the mortar and also prevents long-term structural damage to the brickwork. If the new mortar applied during repointing is stronger and denser compared to the original material, then it can trap moisture inside the brickwork.
With time, this leads to cracks and internal damp issues. Thu, the mortar is important for the older properties where the traditional lime mortar is used instead of the modern cement-based mixtures.
Importance of mortar matching in repointing service
Maintains visual consistency
Mortar makes up a large percentage of the brick’s facade within the visible surface area. If the colour and texture of the mortar do not match the existing structure, then there will be sections that will look odd. Professional mortar matching involves replicating the original colour of the brickwork. The professionals will also match the sand grain size and the texture and recreate the original joint style.
Helps to preserve heritage and property value
If you’re availing repointing services for the listed buildings and period homes, then matching is essential as it falls within the conservation guidelines. Using inappropriate materials will compromise the historic character of the property and even breach the local planning regulations. Thus, matching the mortar is essential as it helps in compliance and also protects the long-term value of the building.
Prevention of future repair costs
Incorrect mortar can hasten the deterioration process. The trapped moisture and the cracks can lead to further damage, which will not be remedied in the next few years. In order to prevent future repair expenses, it is essential to match the mortar with the original composition so that the repointing service lasts for decades. This helps in reducing the maintenance costs and also ensures that the building continues to perform the way it has been designed.
Mortar matching is not a minor part of the repointing service; rather, it is a fundamental element that is essential for a successful repointing service. By ensuring compatibility, durability, and appearance, the professional mortar matching helps to protect the structural stability and ensure consistency in the visual appearance.
