This depends on various factors such as the lime type and content, whether it contains fibres and the ambient temperature. It is possible to move over the floor using boards after a few days, no point loading. The slab will continue to strengthen over the following months. It is possible to lay a floor finish such a stone bedded in a lime based product after 21-28 days but you will need to wait much longer to install a floor such as engineered wood as the moisture content will need to be much lower (2-3%)for this type of floor to prevent it from warping.

We have two volumetric batch mixing trucks, Ronnie and Sally! Ronnie can hold around 8.5-9m3 and Sally can hold around 7-7.5m3 of limecrete. They mix the correct ratios of lime, aggregate and water. These ingredients are then forced through an auger to combine them. When you mix in a conventional drum mixer these different ingredients tend to ball together.

Although the depth of material above UFH may take longer to reach its required temperature. The greater Thermal Mass of the slab with ensure heat is retained.

This can depend on what your architect has specified and in order to meet a specific U-Value. The minimum depth for the slab-less design that we would lay to, with UFH would be 150mm RFG and 100mm Limecrete screed.

The Recycled Foam Glass aggregate that we use needs to be compacted in layers if the depth is above 300mm. The greatest depth that we have insulated so far was 550mm compacted.
