Our specification for original limecrete floor systems is LABC (Local Authority Building Control) approved. This means that seeking approval to install such a breathable, insulating floor system in your home should be relatively simple.
Limecrete floor systems are a modern interpretation of traditional solid floors that can still be seen in many older homes.

Limecrete is an alternative to a concrete floor with or without a DPM (damp proof membrane). Using limecrete floors in traditional houses improves on the relatively impervious, non flexible cement floors which can create problems with dampness being forced into walls at ground level. This in turn can result in poor insulation, mould growth and even structural damage.
Many conservation officers with responsibility for listed buildings would encourage the use of limecrete rather than the concrete floor build-ups required by Building Regulations.
A limecrete floor uses natural hydraulic lime (NHL) that sets quicker and potentially than traditional limeash floors. A mixture of NHL5 and well graded aggregates can be used to create the limecrete slab but it is also possible to introduce breathable insulation using an insulating aggregate, and even underfloor heating.
Limecrete floor systems consist of a non-capillary material at their base to deal with ground moisture. This is followed by a mixture of natural hydraulic lime (NHL) and aggregate as the preferred alternate slab to concrete. They are designed to be a sympathetic, breathable floor system from start to finish.
Installing a limecrete floor system can effectively manage moisture rather than push it into the surrounding walls. The non-capillary action is particularly beneficial in traditional homes to help minimise the damp in surrounding walls.
Using non-capillary insulating aggregates in the base layer manages ground moisture and reduces thermal conductivity. The latter is particularly important when considering the use of underfloor heating systems in your home.
