Hot-mixed lime mortars has become a much talked about topic in the last 3(three) years and CRL Restoration have been at the forefront of advocating the use of hot-mixed lime mortars and disseminating the information that is becoming available to people in the industry.
To this end, CRL Restoration have held 3(three) hot-mixed lime mortar days this year for our clients, conservation architects, surveyors, stonemasons and our own staff. These days have been held in conjunction with Nigel Copsey of the Earth Stone & Lime Company and Associates. Nigel is an eminent authority on hot-mixed lime mortars and a strong advocate of their use.
At Reading Abbey ruins where a NHL 3.5 was specified for carrying out the consolidation works on the ruin walls, CRL Restoration approached the architects for the works and recommended that hot-mixed lime mortars be used instead. After attending one of our hot-mixed lime mortar days they were convinced that it was the right material/method of mixing to be used and the specification was changed.
