What is repointing?
Re-pointing is the process of renewing the pointing which is the external part of the mortar joints. In masonry construction, over time, weathering and decay cause voids in the joints between the brickwork allowing the penetration of damp and moisture, Water entering through these joints can cause significant damage through frost weathering and salt deposition. Damage can also occur more rapidly in built up or urban areas as can the previous use of Portland cement (OPC) which who’s use has been widely criticised as its now understood to cause structural damage to solid wall construction through its high strength restricting the buildings ability to move naturally during movements caused by their thermal change or also through progressive movements more commonly found with building of older construction.
Why use Aspire Restoration for re-pointing?
Aspire restoration have many years of experience with these processes and understand the importance of the pointing and its primary purpose to protect the building from damp and moisture and to improve the thermal loss form the interior. In all cases your property will be surveyed before any works commence. Before any work is undertaken, it is our policy to visit your property whereby a short survey will inform us of the best advise to give you for any potential re-pointing works. At this point we will discuss the options with you and walk you through the process step by step. Many questions that you may have can be answered by our team at this time, A common question we are often asked is about the use of natural lime mortars and their many application. It is essential that any mortar used for re-pointing have similar performance properties to the original mortar used in the building. For instance if a soft lime mortar was originally used, the most appropriate mortar used for the re-pointing should also be a soft lime-based mortar. Our team have specialist training and many years of experience in the conservation and restoration of period properties. When it comes to re-pointing brickwork our methods are sympathetic to your building and our traditional skills and techniques assure that you are in the very best hands of a very high level of workmanship and attention to detail that will transform your building often with dramatic results.
