Lithan Limited is an established company that for many years has been providing independent advice and services with regard to stone and related materials to architects, engineers, contractors and other professionals involved with historic buildings and monuments in both the private and public sectors.

The services are primarily concerned with finding solutions to problems of stone decay and are based on direct inspection and the analysis of the alteration occurring within a particular structure and stone type.

Once the nature and extent of the problems have been defined the evaluation of materials and procedures of relevance to the particular stonework, can be carried out prior to the preparation of a specification. At the planning stages of conservation and restoration projects this information can greatly assist with decision making and ensuring that the appropriate intervention procedures are applied.
