Stone restoration repair
options are broadly the same as those used for other types of masonry
and include complete renewal, insitu surface restoration or consolidation.
Causes of stone masonry failure are most commonly; incompatible
materials placed beside one another, inadequate weatherings and
poor quality repairs. The use of hard mortars in re-pointing is
a common cause for stone deterioration.
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.
Indenting new masonry: 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 and then set in an annulus
of epoxy resin. The stone is then fitted into its position within
the host substrate.
Insitu restoration using reinforced repair mortars: A defective
area of masonry can be cut out and repaired using restoration mortar.
The area of repair is dampened and stainless steel dowels are fixed
into the host area of repair if required, before the area is restored
forward with mortar to its original line and profile. Such repairs
are colour matched to the surrounding stonework as closely as possible.
Pinning and grout injection: Areas of unstable or loose stonework
can be consolidated using grouting or pinning techniques. Grout
is pumped into the unstable masonry structure to bind the masonry
together while producing what is in effect an invisible repair.
Pinning can be used to fix loose pieces of masonry to the main structure
and improve the stability of the substrate. Stainless steel dowels
are drilled into the stonework and fixed in place with epoxy resin.
