Charlestown Workshops, Fife
This workshop is the follow on course from CE1 Introduction to lime based mortars and traditional materials for the repair of civil engineering structures and covers two major techniques for consolidating masonry structures, namely grouting (with a liquid mortar) and concealed crack stitching. These are techniques that may be applicable for the repair of masonry arch bridges, culverts, tunnels, lighthouses, viaducts, canals, harbours, retaining walls, piers and other masonry structures which contribute so much to the richness of our heritage.
This one day workshop focusses on remedying voids in traditional masonry buildings and structures in a sympathetic manner using traditional lime and natural cement bound mortars in liquid form to enable grouting. Techniques of crack stitching (for dormant cracks) will also be addressed using a variety of methods and materials to suit the various scenarios that might occur in heritage buildings and structures. This workshop is a mix of theory and practical hands-on work.
This course is suitable for Structural and Civil Engineers and their Technicians including those that look after our roads and railway networks, contractors working on unprotected masonry structures and ruins and custodians of our industrial heritage. This course may also be of interest to Architects and Building Surveyors dealing with ruined structures and buildings.
