It is not uncommon for homeowners to experience cracks in the mortar of their brick homes. The cause of these cracks can be attributed to a variety of factors, including:
Temperature changes
Soil movement (i.e., expansion and contraction)
Building settling
Will it hurt my home?
Although it may seem unsightly, having cracks in your mortar is not considered a structural issue and will not affect the integrity of your home. Cracks that are less than 1/8″ wide are typically nothing to worry about. While you may have experienced some hairline cracking, if you notice any gaps that are more than 1/8″ wide allow us to take a look! These larger gaps can potentially cause moisture intrusion and damage to the underlying structure.
How do I fix it?
If you’re handy with tools and would like to tackle this project on your own, here are the steps to fixing cracked mortar joints:
1. Remove the cracked or loose mortar using a hammer and chisel or other specialized tools. Try to remove as much damaged material as possible without damaging surrounding bricks. This step requires careful attention so that you do not chip away too much or damage the bricks themselves. If you are uncomfortable removing the old mortar yourself, give us a
The ability to fix cracks in concrete walls, floors and foundations is a skill many home and business owners will find useful. Knowing how to patch these cracks will not only help you maintain the value of your property but also prevent more serious damage from occurring.
When cracks form in the foundation of your home, they should be repaired immediately to prevent water from entering the interior. If water seeps into a crack, it can cause further damage such as mold or mildew.
The first step in fixing a crack is to make sure it is clean and dry. This can be done by using a vacuum cleaner to remove any dust or debris that may have gotten inside the crack. You should also use an air compressor if there are any loose pieces of concrete that need to be removed before beginning repair work on them.
Once everything has been cleaned up, you should apply some type of sealant over top which will help prevent water from seeping into the crack again in future seasons!
Lime Mortar Mixes for Repointing Brickwork
Lime mortar mixes are used extensively in the restoration and repair of historic buildings. They are also used in modern construction where a more breathable, softer and more permeable mortar mix is required. The following information is a quick reference guide to the lime mortars used in repointing brickwork.
It is not intended to be a definitive guide to all the different types of lime mortar mixes, nor does it cover specific recipes for making mortar that you may need to use when repairing your building. We intend to cover these topics in later posts so make sure you subscribe to our newsletter (below) so you can stay up-to-date with our latest articles.
Why Use Lime Mortar?
The most common material used in the construction of buildings is brick, stone or concrete block masonry. These materials have been used for thousands of years and the reason they are still being used today is that they are reliable, durable and relatively easy to work with.
A major problem with many modern construction materials is that they do not allow water vapour or moisture to pass through them. This means that any moisture trapped inside a wall will have no where to go and may eventually lead to structural damage from frost
Lime mortar is composed of lime and an aggregate such as sand, mixed with water. The Ancient Egyptians were the first to use lime mortars. About 6,000 years ago, they used lime to plaster the pyramids at Giza. Mortar is a workable paste which dries hard when subjected to the influence of water. It is used extensively in the building industry for bonding bricks, concrete blocks, stones, tiles etc.
Lime mortar mix is mostly used in the repair and construction of older buildings and structures that contain soft brick, stone or other calcium-rich building materials. Lime mortar is softer than cement mortar therefore it has a greater adhesive strength and creates a much stronger bond to brickwork and stones than cement. Lime mortar also allows movement within the wall due to its elasticity and flexibility which reduces the potential for cracks to form.
For this reason it is often used in older properties or where significant movement might be expected such as on uneven walls or foundations.
The use of lime mortar in masonry construction, particularly in the repair and restoration of older buildings, has been rising steadily for over twenty years. This increasing popularity can be attributed to the understanding of the benefits of lime mortar over cementitious materials, and the recognition that traditional masonry materials are essential for preservation of historic structures.
Lime mortar consists of lime and an aggregate such as sand, mixed with water. The mix may contain lime putty, hydrated lime or hydraulic lime. Lime is a term that refers to both calcium- and magnesium-containing compounds, which can be either quicklime (calcium oxide) and slaked lime (calcium hydroxide), or hydrated lime (calcium hydroxide). For defining the different types of lime mortars it is useful to refer to their setting characteristics, which are determined by their composition (e.g., amount of hydraulic components) and curing conditions.
Lime mortar is used as a binding agent in masonry construction. It is applied between blocks or bricks to harden them into a single unit. The ability of lime mortar to adhere to surfaces helps hold masonry together, yet allows for easy deformation to relieve stress from slight shifts in temperature or other movement within the structure.
For many centuries, lime mortar has been the binder of choice for stone and brick construction. The binding quality of lime mortar is dependent upon the proper ratio of ingredients, which means it must be mixed correctly and applied properly. This article will discuss the basic properties of lime mortar, how it’s made and how it should be mixed.
Lime mortar is composed of a mixture of hydrated lime, sand and water. Hydrated lime is available in several types, but the most common type used in construction is type S (ASTM C-207). Common masonry cements are not suitable for mixing with lime mortars because they contain portland cement which can cause cracking as the structure settles or expands and contracts with changing temperatures and moisture conditions.
Sand is an important ingredient in a lime mortar mix because it’s what gives the mortar strength. The type of sand used should be clean and course with no organic material such as clay or silt. Sand that contains organic materials can cause staining on the face of masonry units.
Another important component to consider when making a lime mortar mix are admixtures that can improve its workability. Some examples include pozzolanic materials such as fly ash which help reduce shrinkage in
