Limecrete floor detail.

This might be a bit detailed for some of you but i have been researching the use of limecrete as a breathable kitchen floor for some time and have found very little good advice on t internet. The limecrete slab having a more open pore structure on a molecular level than concrete can also provide a buffer to moisture vapour. It prevents damp penetration provides insulation maintains breathability and provides a solid durable floor in character with the original building. A hybrid floor is an option where a modern floor is constructed in the centre of the room with a trench between the concrete floor and the surrounding walls see diagram above.

Glasscrete is a modern form of limecrete floor that incorporates geocell foam glass gravel as the moisture managing insulating base. A limecrete floor laid on foamed glass is seen as one way of helping with this problem. Although not essential you can use insulation values based on requirements set by building regulations as the goal for many floor systems that incorporate underfloor heating. Limecrete floors can comfortably meet modern insulation requirements and can therefore ensure maximum efficiency of under floor heating ufh systems.

The original limecrete floor is a modern interpretation of a traditional solid lime or gypsum floor that can still be seen in many historic or well preserved older homes. Hence i thought that some detail in the public domain might be found useful. Mike wye offer an option for an insulated limecrete floor using an insulating coated clay aggregate as an effective capillary break. Mike wye the lime specialist have a good guide but we found that availability and cost of materials was a problem as was the definite mix ratio so here s how we did it.

Limecrete floor there doesn t appear to be a concencus on the ideal way to lay an insulated breathable limecrete floor. Limecrete is never left without a covering of tiles flags or engineered timber on battens and these are laid on a screed and bedding mortar above the insulating limecrete. Ty mawr s sublime floor was the first insulated limecrete flooring to achieve the labc local authority building control registered detail and so it is recognised in all 376 local authority areas. The thickness of the slab 100mm means that moisture vapour will not be transferred straight through the slab but rather it is buffered in the lower half of the slab and the top of the slab should always stay dry.
