Quadriga

Church Renovation

Quadriga offers systems of repair which sympathetically conserve and restore masonry and stone, preventing further deterioration, either structurally or aesthetically and enabling full Church Renovation.

Church renovation repair options are broadly the same as those used for other types of buildings with masonry and include complete renewal, insitu surface restoration, or consolidation.

External church stonework often requires cleaning in order to adequately identify concealed defects. Once diagnosed, various 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 the existing church structure to replace defective areas of stonework.

INSITU CHURCH RENOVATION 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 it's original line and profile.

PINNING AND GROUT INJECTION TO CHURCH STONEWORK

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 church stonework and fixed in place with epoxy resign.
