Hydraulic Lime Mortar

Why Use Hydraulic Lime Mortar?

Lime 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.

What Are The Benefits?

Lime mortar has many advantageous properties over cement; it is weaker than the bricks, masonry and stones, yet it is able to support the full weight of the structure. This gives the building the ability to flex and move without the purpose of movement joints. There are many other benefits for using it too.

Breathability 2

A common problem with modern houses is they are becoming less and less breathable. Lime allows moisture to evaporate and wall to breathe.

 Absorbs Co2

Lime has a very unique benefit to any other building material currently available. When curing process starts it re-absorb CO2 from the atmosphere.

Recycle Masonry 2

It allow masonry to be recycled at the end of the buildings life.

Movement Joints

Modern buildings using cement will generally have an expansion joint every 8 metres. By not using cement, you can have an expansion joint every 20 metres.

Flexibility

Lime mortar has a low modulus of elasticity, which allows for slight movement and thermal expansion throughout the life of the building.

Ready Mixed

Our mortars are ready mixed at our state of the art factory. This removes the possibility of inconsistent colour and strength that can occur during site mixing.

Which One Should I Use?

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

Ashlar is used for a finely dressed (worked) masonry, which is a very thin joint between blocks and generally used for 3mm to 6mm joints.

NHL 3.5 strength can be used for permeable masonry materials which is mainly used above ground. Generally, it is used for bricks, facings, commons, blockwork, bedding, sandstone, limestone, flint, terracotta, cavity, solid walls, pointing and repointing.

NHL 5

NHL 5 strength is commonly used for the foundations of buildings, coastal locations, or for parapets, coping’s and chimneys in external areas.
