Buying the component parts for limecrete floors

Ty-Mawr developed this system of insulated limecrete flooring for historic properties where a dense concrete slab was inappropriate, however it is equally useful in new builds as an ecological alternative to concrete. We are able to design a floor build-up for you to meet current building regulations as well as supplying the materials.

The best way to calculate the quantities of materials required is to get us to design floor build ups and undertake calculations for materials required - there is a £30 charge for this service. This charges are refundable if/when your order is placed. We will contact you on receipt of your form for preferred payment.

“…the Museum faced the challenge of introducing heating into the building, which was clearly not designed and built with heating in mind. This not only raised practical issues, but also but also matters of principle and authenticity. Balanced against these are questions of personal comfort (for the visiting public and the Museum's own warding staff) and conservation. The latter point is of particular importance within the context of restoring an old building which incorporates both original (in this case medieval) timberwork and modern replicas. Both require special conditions to ensure that they are not adversely affected by the temperature, and more importantly, Relative Humidity, prevailing within the building.

Excessive heat and/or dryness would, for instance, cause the timbers to dry out too quickly, resulting in twisting, shrinkage and cracking; whilst the lime-plastered walls would crack, loose adhesion and fail. Conversely, too much moisture and/or very low temperatures would result in condensation and mould growth. It was important therefore to find a method of controlling the relative humidity levels within the building so that both the historic, and new oak, timberwork would not be adversely affected. The use of a controllable under-floor heating system combined with an insulated limecrete floor fed by a Ground Source Heat Pump was seen as an ideal way of minimising such problems, enabling the building to dry out gently and naturally, whilst moderating the internal environment for staff and visitors”.

The 'breathing' qualities of the floor make it highly suitable for solid wall construction buildings as it works in harmony with the rest of the building. It has therefore also been used in 100s of private restoration projects for individual rooms or complete ground floors all over the UK.
