	Limecrete is a combination of natural hydraulic lime and lightweight aggregate such as sharp sand or glass fibres. This creates a breathable material which can be used as an alternative to concrete, in particular for floor slabs in the conversion of old buildings to modern standards - helping to deal with naturally occurring moisture. Limecrete can help to resolve design problems associated with older buildings and energy efficiency, while retaining a traditional character and aesthetic.

Limecrete is a combination of natural hydraulic lime and lightweight aggregate such as sharp sand or glass fibres. This creates a breathable floor slab which is often used as an alternative to concrete by architects as a means of converting old buildings to modern standards and helping to deal with naturally occurring moisture.

In terms of flooring, limecrete can help to resolve design problems associated with older buildings and energy efficiency, while retaining the character and aesthetic. Modern buildings are built so as to be able to adequately deal with moisture without requiring breathable construction such as limecrete.

Limecrete is strong enough under compression to serve as a floor slab material, and can be strengthened by adding fibres and increasing the lime content. Care should be taken with the mixing, since excessive lime content can compromise the breathability.

By installing a limecrete floor, moisture that may or may not rise from the ground can be preventing from being pushed by the slab to the walls and causing damp issues. Instead, the slab ‘breathes’, allowing water vapour to escape, and behaves in a similar way to other natural building materials such as timber, straw and earth.

Limecrete is often laid on a base of foamed glass beads rather than hardcore, without a damp proof membrane (DPM). This enhances the breathability of the slab, since hardcore can allow capillary action to draw up ground moisture. Foamed glass beads are the most common option since there are few other non-capillary substrate materials available.
