Repairing traditional masonry structuresBook courses
This one day workshop covers the construction and appropriate repair of traditional masonry structures such as culverts, tunnels, light houses, viaducts, canals, harbours, retaining walls, piers and masonry arch bridges using natural stone and the range of lime and early patented cements that have been used in the past as bedding and pointing mortars. These structures contribute so much to the richness of our built heritage and many are still in use after 200+ years.
