Lime mortar has been used for centuries as a building material due to its durability and breathability. However, there is a common misconception that lime mortar is not waterproof. In this post, we will explore the truth behind this myth and provide you with the information you need to make an informed decision about using lime mortar in your construction projects.
Firstly, it is important to understand that lime mortar is not completely waterproof. However, this does not mean that it cannot be used in areas where water is present. In fact, lime mortar is often used in areas such as swimming pools, fountains, and other water features.
The reason for this is that lime mortar is breathable, which means that it allows moisture to evaporate from the surface. This prevents the buildup of moisture within the mortar, which can lead to cracking and other damage. Additionally, lime mortar is able to absorb small amounts of water without compromising its structural integrity.
It is also worth noting that lime mortar can be made more water-resistant by adding certain additives. These additives, such as pozzolanic materials, can improve the strength and durability of the mortar, making it more resistant to water damage.
In conclusion, while lime mortar is not completely waterproof, it is still a highly durable and reliable building material that can be used in a variety of applications. By understanding its properties and limitations, you can make an informed decision about whether or not to use lime mortar in your construction projects.
