Hydraulic Lime Binders
Natural 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 lime, and many parts of Europe are still using it in New builds today. 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.
Benefits Of Natural Hydraulic Lime Binder
Lime & cement when used in construction both provide the same purpose of joining brickwork together. However, 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. 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.
- Reduces the need for expansion joints
- Uses less energy to produce than cement
- Consistent quality and colour of mortar
- Re-absorbs CO₂ when it cures and sets
- It can be produced as and when needed
- Provides a breathable form of construction
- Deterrent against pilfering and reduction in wastage
- Aesthetically enhances masonry
- Provides a water shedding barrier for walls
- No need to allocate one individual for mixing
- Allows masonry to be recycled at end of life
- It can be re-worked for up to 24 hours

Tradical Hemp Binder
Tradical Hemp Binder is a special lime binder design to be used with hemp shiv for mainstream construction. Hemp binder is very unique compared to other building materials due to its ability absorb CO2 throughout the building’s life, making a significant contribution to combating global climate change. The overall CO2 balance for Tradical hemp binder and lime products is such that captured carbon is retained within the fabric of a building.
Limetec have been producing a variety of products for over a decade and have been developed to meet an array of building specifications from repointing, structural work and internal / external purposes.
With our range of eminently, moderately and ashlar mortars we can guarantee a perfect match for your renovation, new build and conservation needs.
Our Render offers a variety of benefits over cement based products for new builds; as it provides a greater level of breathability which is why conservationist predominantly use it for conservation and renovation buildings.
Render is the ideal solution for damp walls as the water is not trapped and able to evaporate. When the water cannot evaporate, this can lead to damaging brickwork, stone masonry and wood. Render is robust and malleable to cracking and crazing to other forms of renders on the market.
The Limetec brochure is an A4-size, 16 -page, full colour guide to specifying breathable energy efficient products for new builds and conservation projects. Covering the full range of Mortar, Render and Plaster products including; the benefits over cement, specification guides and a variety of case studies with have worked on over the years.
