Structural crack repairs
Structural crack repairs are repairs to cracked masonry walls that restore strength and keep the weather out, chosen after the crack’s type, width and cause have been identified. They range from repointing a hairline crack to stitching or rebuilding a wide one.
Crack stitching
Crack stitching is a masonry repair in which stainless steel helical bars are bonded into slots cut along the mortar bed joints, bridging a crack so the brickwork carries load as one piece again.
Wall tie replacement
Wall tie replacement is the installation of new stainless remedial ties to reconnect the two leaves of a cavity wall when the original metal ties have corroded, with the old ties isolated or removed where specified.
Bowing wall repairs
Bowing wall repairs are repairs that stop a bulging or leaning masonry wall moving further, usually by fixing it back to the floors and roof with restraint ties and straps, and rebuilding only the sections too distorted to keep.
Gable end wall repairs
Gable end repairs are repairs to the triangular wall at the end of a pitched roof, typically tying it back to the roof structure with restraint straps or rebuilding its upper part where it has leaned or loosened.
Lintel replacement
Lintel replacement is the removal of a failed lintel above an existing window or door and its replacement with a new one of the right size and bearing, with the wall above temporarily supported while the work is done.
Brick arch repairs
Brick arch repairs are repairs to the arched brickwork spanning a window or door, either reinforcing a sound arch with stainless bars or taking down a failed one and rebuilding it over a temporary timber former.
Chimney stack repairs
Chimney stack repairs are repairs to the brickwork that rises above the roof, from repointing and renewing the flaunching around the pots to restraining a leaning stack or rebuilding it from the roofline up.
