Advantages of Limecrete vs Concrete

- The Limecrete slab (having a more open pore structure on a molecular level than concrete) can also provide a buffer to moisture vapour. 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.
- The slab provides thermal mass resulting in increased efficiency of the UFH,
- Reduced labour costs as only one slab is needed
- LABC approved Detail without the need for a DPM.
- No Expansion Joints - Our research has suggested that the considerations applicable to cementitious concrete with regard to expansion joints are not applicable to lime-based concretes. Hydraulic Lime generates little heat during the initial chemical hydraulic set and Limecrete has a good flexural strength to compressive strength ratio. These properties mean that huge savings can be made in terms of the labour and equipment usually required to fabricate dowelled and induced contraction joints in cement concrete ground bearing slabs.
- The flexural strength of Limecrete copes with movement normally found in solid wall building – reducing the risk of cracking.
