Brick and stone repair
CA building restoration offers a wide-range of expertise in dealing with
restoration and protection of brick and stone, from intense heat or humidity
to brittle cold and winds.
Repairing damaged bricks or stonework begins by identifying and
understanding the reasons for decay. The usual reasons are excessive
moisture, poor repairs, mechanical damage and natural decay. A major reason
for damage is inappropriate repairs. Hard pointing or cement-based repair
materials are very damaging. Lime-based material, is flexible, porous, and
lets the building breathe. Hard cement-based materials trap in moisture and
salts. Patching brick or stone can be very effective, affordable and can be
reversible. The patching material must match the color and texture of the
stone or brick.
When deterioration has occurred, detailed analysis is done testing the
degree of decay, original composition and color of the brick, stone and
mortar, and restoration is commenced.
When replication is necessary, and deterioration such as crumbling, deep
cracking or missing artifacts has occurred, we re-creates the artifact
matching brick or stone color and composition.
Replace of Brick and stone
Brick removal must be done either for replacement or when the mortar has
deteriorated to the point of loosening the brick from its neighbors. If
mortar has completely deteriorated, multiple bricks will likely need removal
and rebedding. If the brick is a veneer over a wood building, metal ties
between the brick and wood sheathing and deteriorated tar paper will likely
need to be replaced also. Individual spalled bricks can be difficult to
remove without disturbing nearby sound bricks. But using an angle grinder or
an abrasive blade can successfully cut out mortar joints around bricks.
Any bricks in the wall that are badly broken or deteriorated should be cut
out and replaced (prior to re-pointing) with the selected new bricks that
match the old bricks as closely as possible.
