Levelled and compacted ground.
Limecrete floor specification.
Layer of geotextile membrane.
These floors are also chosen for ecological new builds using natural materials such as straw and wood because it uses less energy in production avoids the use of cement and is recyclable at the end of its useful life.
U f heating pipes attached to grid.
Layer of geotextile membrane.
Limecrete floor 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.
It is lightweight and insulating having a loose bulk density of 150kg m3.
100 mm 450 mm compacted geocell foam glass.
Fine grade required for 150 mm layer of geotextile membrane.
100 mm 150 mm limecrete slab 3 parts un coated techniclay to 1 part nhl5 by volume with 30 mm cork board to external perimeter walls.
It prevents damp penetration provides insulation maintains breathability and provides a solid durable floor in character with the original building.
Layer of geotextile membrane.
Levelled and compacted ground.
A limecrete floor laid on foamed glass is seen as one way of helping with this problem.
This is followed by another layer of geotextile and limecrete produced using lightweight insulating aggregate rather than conventional sand.
Layer of geotextile membrane.
Mike wye offer an option for an insulated limecrete floor using an insulating coated clay aggregate as an effective capillary break.
Fine grade required for 150 mm layer of geotextile membrane.
Geocell is an aerated foam glass aggregate made from recycled glass.
A sub base between 200mm to 300mm made up of geocell laid onto a geotextile membrane on firm ground.
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.
Levelled and compacted ground.
100 mm 450 mm compacted geocell foam glass.
Limecrete floors offer an alternative to impervious non flexible cement concrete floors.
100 mm 500 mm layer of loose fill 10 20 mm coated techniclay.
