Natural Hydrolic Lime
Limecrete, a combination of natural hydraulic lime (NHL) and aggregate, is seen as a ‘green’ building product as its manufacturing carbon footprint is lower than producing concrete.
It also absorbs Carbon Dioxide in the drying process.
A Limecrete slab enables vapour to escape, reducing damp and mould issues, and therefore is often prescribed for listed buildings for restoration authenticity and practical reasons such as vapour control.
With high flexural strength, Limecrete copes with absorbing natural movement in both old and new buildings and this flexibility, coupled with high thermal mass, makes Limecrete ideal for use with the reconstruction of solid floors as well as with under floor heating (UHF).
Foam Glass Aggregate
As a sub-slab insulator, foam glass can be used to thermally insulate beneath a Limecrete slab while also acting as a drainage layer/capillary break.
As most period properties have their floors built directly on earth, usually with a thin layer of lime mortar and ash underneath, it is common for moister to rise to the surface, by capillary action, making your floor wet, particularly during rainy periods.
As Foam Glass can be used to create a breathable sub-base, it is an ideal material for period floor construction.
Foam glass can replace rigid foam board and crushed stone aggregate as a 2 in 1 solution for insulation and moisture separation i.e. a capillary break.
