Lime mortar training course on Saturday 6 June

Thinking about having some repointing done on an old house or wall in the coming months or years? If so, why not come along to this training event on Saturday 6th June in Bewerley.

In Upper Nidderdale, like many parts of the British Isles, most homes built before the First World War were constructed of locally sourced materials, for example the grey gritstone that you see all over Upper Nidderdale in walls, bridges, dams, barns and houses.

Three people lime mortaring a traditional stone building

Traditional materials can be incompatible with modern materials; and so it is important to be aware of potential problems when carrying out repairs or alterations. Cement-based mortars are often used in repairs to historic buildings with the best of intentions, however over the years the damage which cement-based mortars can cause to historic masonry have become very clear and you may have seen cement-based mortars standing proud of decayed stone or brickwork.

Lime mortars are important in the conservation of historic buildings as they allow moisture trapped in the wall to evaporate through the joints, rather than being either trapped in the wall or evaporating out through stone or brick, causing damage to the stone or brick face.

  • If you would like to find out more and even have a go, join the Upper Nidderdale Landscape Partnership team at this informative and informal event.
  • This is a partly practical day so suitable (old) clothing will be required. Safety equipment such as goggles and gloves will be provided, but please feel free to bring your own if you have them.
