Lime Mortar has been used in the construction of buildings for over 2000 years, and used on the most iconic historical landmarks across the world. For example, the Great Wall of China, the Houses of Parliament and Rome Colosseum. These historical buildings are still here today, due to its unique beneficial properties.
Lime gives the building the ability to flex and move without the need for movement joints in many cases.
There are many other benefits for using it too.
Strength is the most important aspect when rebuilding your wall or pointing it. There are two strengths generally; depending on what type of brick, masonry, block work and location you are working on. Also, there are two types of finishes which will require a certain product, a very thin joint which is 6mm and below or a 7mm and above joint size.
Ashlar (fine) mortar is used for dressed (worked) masonry which has very thin joints between blocks and bricks, generally between 3-6mm. The joints can be recessed or flush. The mortar uses a fine aggregate and can be supplied is the full range of heritage colours.
HLM 2.5 strength can be used for permeable masonry materials, mainly used above ground. Generally, it is used for bricks, facings, commons, blockwork, bedding, sandstone, limestone, flint, terracotta, cavity, solid walls, pointing and repointing.
This is commonly used for the foundations of buildings (below dpc), parapets, copings and chimneys in external areas. It is also used in extreme coastal and mountainous areas. The colour will match the HLM 2.5 mortar so there will be no change from below to above dpc.
At the request of our architects and construction clients, we have developed a new range of lime mortar colours to compliment our award winning Heritage Range.
