The team at USL were pleased to work on the medieval parish church dedicated to St John the Baptist, in Great Amwell near Ware. The nave and chancel date from the 11th century with a Norman chancel arch.

This Grade II* listed building was in need of stonework repairs to the tower across all elevations. The stonework which comprised of Clunch and flint elements required urgent conservation intervention to reduce further decay and weathering.  The project included conservation works with stone cleaning, stone masonry and mortar repairs, new stone replacements, repointing and Nanolime treatment.

Nanolime Treatments for Historic Stonework

USL employed the use of Nanolime in the treatment of historic stonework against decay and increased weathering.

CaLoSiL® is a ready to use stone consolidator, which contains calcium hydroxide nano-par-ticles stably dispersed in different alcohols. Used for structural conservation and consolidation of stone. Consolidation of decaying stone is required in order to increase its durability and prevent or reduce further decay from weathering, moisture or pollution.
