| Limecrete is ... |
| Limecrete is a mixture of natural hydraulic lime (NHL) and aggregate that can be used to create breathable floors. It offers increased vapour permeability which is especially important for traditional buildings, and is often used in combination with breathable membranes and sometimes without a dpm. |

| Concrete and CO2 |
| It used to be a rule of thumb that a tonne of concrete produces a tonne of CO2. Lime is slaked at lower temps that cement. And lime mortar is much more suitable for pointing pre 1950s buildings, as it remains flexible and can move with the building. Concrete mortar is stonger than the bricks, stops the building flexing, casuses stress on other elemnts and can cause cracks in the brickwork. |
