Not all lime is made equal! Our high-grade lime contains a minimum 92% calcium and is especially suited to construction.
Lime is an excellent construction material. Widely available, once set it forms a hard finish that is less brittle and less prone to cracking than cement-based materials.
Producing lime creates fewer emissions than producing cement – by a significant factor. In fact, lime can be produced with nearly 97% less emissions than cement.
A tale as old as time
Lime is one of the world’s oldest construction materials and has been used in some of the world’s most recognisable buildings.
The use of lime in building construction began thousands of years ago, with lime binder in use in the western world from 6000BC, with debated evidence of earlier uses. Lime was used in Greece and appears in a 25BC Greek guide to building – Vitruvius’s De Architectura. In the 11th century, lime was used in stone structures built in England after the arrival of the Normans – including castles and churches built by William the Conquerer to help gain control over the English. In the mid-1800s, a patent was lodged for a mixture called Portland cement. By the turn of the century, lime was falling out of popularity in favour of cement.
Cement requires higher temperatures to be produced than traditional lime. In some applications, cement based products can be replaced with lime based products, which creates a manufacturing emissions saving.
Not a one trick pony
Hemp lime | Hemp blocks | Mortar | Exterior render | Internal render
We use lime in our hemp-lime blocks and mixes. Lime is an ingredient in the mortar used to adhere hemp-lime blocks and fill any tiny air gaps. Lime can also be used to create easy to use renders and plasters to provide a durable and weatherproof finish.
