Over the last 5 years, there has been a growing awareness of the historic ubiquity of earthlime and hot mixed lime mortars and a renewed emphasis upon like-for-like repair of traditional buildings, as well as important research into the character and performance, as well as the historic precedence, of Natural Hydraulic Lime Mortars.  

Event description: 

Like-for-like and compatible repair will usually require the use of earth-lime and hot mixed lime mortars. The York Symposium aims to bring together all current thinking and knowledge about traditional mortars, presenting recent research outcomes, revised heritage agency guidance and case studies from around the UK, Ireland, Spain and Canada. The speakers will be drawing upon long and more recent experience using traditional mortars for the repair and conservation of historic fabric, sharing their insights and knowledge in theory and in practice. The Symposium is intended to allow the informed specification, mixing and confident use of earth-lime and hot mixed lime mortars, as well as demonstrating their historic prevalence, usefulness and enhanced performance characteristics. It is aimed at conservation professionals and practitioners, as well as homeowners and general builders.
