Limecrete Floor Slab

Mix the uncoated techniclay with natural hydraulic lime nhl 5 to form the limecrete slab.

Limecrete floor slab.

Limecrete is strong enough under compression to be used as the floor slab in a home. It is therefore suitable for use in older traditional buildings as well. Fibratec v12 concrete fibres can be used for additional reinforcement optional floor finish bedding screed 20 50 mm of 2 parts aggregate to 1 part nhl5 if using flagstones or tile as a finish. It prevents damp penetration provides insulation maintains breathability and provides a solid durable floor in character with the original building.

Glasscrete is the modern interpretation of a limecrete floor system using geocell foam glass aggregate as its insulating moisture managing base. A limecrete floor laid on foamed glass is seen as one way of helping with this problem. We successfully work with limecrete inside during the winter by heating the water. Grout with 2 parts aggregate to 1 part nhl.

2 parts aggregate 1 part nhl5 by volume with 30 mm cork board surround. This makes it suitable for applications such as a workshop floor. Underfloor heating works well with limecrete and can be laid directly in the slab or installed in the screed. The limecrete slab is made from a blend of natural hydraulic lime and recycled aggregates and can be used as an alternative to concrete in certain applications including as a breathable floor slab in old solid wall buildings or as part of an insulated foundation system.

It can be strengthened by increasing the lime content and by adding fibres. The limecrete slab having a more open pore structure on a molecular level than concrete can also provide a buffer to moisture vapour. We offer fibre re enforcement to provide greater strength sooner without compromising the breath ability or life of the limecrete. A limecrete floor can be designed to meet modern insulation requirements and can incorporate under floor heating ufh.

It is a viable and improved alternative to expanded clay aggregate used in original limecrete floors and is also capable of being used as a load. Where a new floor slab is to be created one option is to use a slab based on lime limecrete which is breathable rather than one based on cement concrete which is less permeable. It is used as an insulating layer below the limecrete slab.
