Limecrete flooring offers a practical and sympathetic solution for historic buildings where breathability and moisture movement are essential to the long-term health of the structure. Unlike modern concrete, limecrete allows moisture to evaporate naturally, reducing the risk of trapped damp and helping to protect surrounding walls, timbers, and finishes. This makes it particularly well suited to older properties with solid floors, especially those constructed with cob, stone, or brick.
Our approach to limecrete floors is always guided by the needs of the individual building. We begin by carefully assessing existing floor structures and ground conditions, often removing impermeable concrete slabs that may have contributed to damp issues over time. The build-up of a limecrete floor is then designed to suit the site, typically incorporating a breathable sub-base and insulation layer where appropriate, followed by the limecrete slab itself.
Underfloor heating can also be incorporated within the limecrete slab, providing a gentle and consistent source of warmth. This form of heating works particularly well in older buildings, helping to maintain an even temperature and reducing the sharp fluctuations often associated with conventional heating systems. The result is a more comfortable internal environment that supports both the building fabric and its long-term performance.
Attention to detail is key throughout the process. We use carefully selected aggregates and lime binders to ensure compatibility with the building, and we place and cure the material in a way that promotes strength while retaining flexibility and vapour permeability. The finished surface can be left as a simple, functional floor or prepared to receive a wide range of traditional finishes, including stone flags, bricks, or tiles.
Limecrete flooring is not only about performance but also about maintaining the character and integrity of a historic building. By working with the natural behaviour of the structure rather than against it, these floors form part of a holistic approach to conservation. Combined with appropriate wall finishes and good detailing, they help create a balanced internal environment that supports both the building and those who use it.
