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.

 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.

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.

Recycle Masonry  2

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


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

Reduces Expansion Joints

Modern buildings using cement will generally have an expansion joint every 8 metres. By using lime you can have an expansion joint every 20 metres.


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