hydraulic lime has been used as a binder for brick, stones and masonry for thousands of years. Before 1900 nearly all buildings constructed across Europe will have been built using it, and many parts of Europe are still using it for new builds. One of the main benefits is it reduces green house gas effect due to reabsorbing over its lifetime of the mortar, thus being close to carbon neutral.
What Are The Benefits?
Lime and cement when used in construction both provide the same purpose of joining brickwork together. However, it 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. As a result 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.
A common problem with modern houses is they are becoming less and less breathable, it allows moisture to evaporate and wall to breathe.
When curing process starts it re-absorb CO2 from the atmosphere, which is a unique benefit to any other building material currently available on the market.
Recycle Masonry 2
It allow masonry to be recycled at the end of the buildings life.
Less Expansion Joints
Modern buildings using cement will generally have an expansion joint every 8 metres. You could have an expansion joint every 20 metres.
Otterbein has a low modulus of elasticity, which allows for slight movement and thermal expansion throughout the life of the building.
Otterbein is leading the way in binders. With its rich creamy white colour and a higher yield when compared to other manufactures; which is why it’s becoming the number one choice of builders lime for merchants.
