Limecrete Flooring System

‍
The use of limecrete is desirable in a historic building as it allows naturally occurring moisture to escape through the floor. The use of modern cement floors has caused some problems, as moisture is unable to escape through the floor and is pushed towards the walls and can cause damp patches to occur in or around the base of the wall.

Limecrete floors offer an alternative to impervious, non-flexible cement concrete floors. 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.

Glapor recycled foam glass insulation may be used in conjunction with a limecrete slab for insulating values. Glapor Foam Glass Aggregate is an insulation material for underground use. Recycled foam glass aggregate saves energy and also contributes to a comfortable indoor environment.

The control of ingress of moisture in a limecrete floor is achieved by using a layer of recycled foamed glass gravel beneath the slab material. Its non-capillary active closed cell structure provides the moisture protection for your floor while remaining vapour open. This material also has an excellent thermal resistance capability (0.078W/mK).

It provides the main load-bearing element of the floor as well as providing thermal mass, it has good insulating properties, reduced carbon costs compared to other floor slab materials, zero harmful off-gassing and is breathable and lightweight.

The Roundtower Limecrete Flooring system can be designed for use with or without underfloor heating. Limecrete floors are a perfect marriage between traditional building and modern technology.
