Metropolitan Stone

Metropolitan Stone specialises in stone repair and restoration involving complete renewal, insitu surface restoration or consolidation. Causes of stone masonry failure are most commonly; incompatible materials, inadequate weathering and poor quality existing repairs.

External stonework often requires cleaning in order to adequately identify concealed defects. Once diagnosed, various repair methods can be adopted depending upon the type of stone masonry and the extent of the decay.

New pieces of masonry can be indented into an existing structure to replace defective areas of stonework. Each piece of stone is carefully measured and cut to fit before stainless steel dowels are drilled into the stonework, set in an annulus of epoxy resin. The stone is then fitted into its position within the host substrate.

Stone repair can also involve cutting out the bad repairs to the defective masonry using restoration mortar. Non ferrous reinforcement is provided where necessary to build out the repair which are then colour matched to the surrounding stonework as closely as possible.
Pinning and grout injection can also be used to repair stone. Grout binds the defective stone producing in effect and invisible repair.
