Limecrete Floors

Geocell Logo

Limecrete and Geocell floors offer a breathable and insulating alternative to impervious floors.

A limecrete floor is usually made up with:

A sub-base between 200mm to 300mm, made up of Geocell laid onto a geotextile membrane on firm ground. Geocell is an aerated foam glass aggregate made from recycled glass. It is lightweight and insulating having a loose bulk density of 150kg/m3. The Geocell is compacted and a layer of Geotextile membrane is laid over the top.

Where underfloor heating pipes are being installed a Geogrid mesh is laid over the Geocell which the pipes are tied to.

A limecrete screed is laid down at an approximate depth of 80mm using a mix of Natural Hydraulic Lime (NHL5) and coarse sand. Movement joints will be required in large areas of screed with heating pipes.

The perimeter of the screed is insulated with a cork insulating board.

Floor slabs being laid onto the screed will require a lime mortar for bedding, resulting in a breathable floor. Lighter weight tiles will require adhesive which reduces breathability. Wooden floors should be ventilated using either vents or spaces at the perimeter under the skirting. If carpets are required, then a well ventilated wooden floor is required.
