Once
the mortar joint between the brickwork
deteriorates, water is no longer repelled. This
problem can allow water to be absorbed into
the brickwork. Left unchecked, the outcome
can result in structural failure to part or all of
the building.Tuckpointing/Re-pointing
the joint will not only
rejuvenate the look of your building, but will seal
your building from the harsh Australian climate.
Tuckpointing
Usually found in older buildings. Tuckpointing is
the
placement of a white or black line on a coloured
stopping (the stopping fills the mortar joint and hides
any defects in the bricks). This gives the impression
the bricks are of uniform size and have been laid
to an accurate gauge. Modern production of bricks
has superceded this process and is rarely applied today.
Replacement of the joint is a time honoured skill.
Incorrect mixing or application can result in early failure.
Correctly done with traditional materials and the results are
impressive.
Re-Pointing
Loose or missing mortar can be replaced with a coloured
mortar to match existing. In older buildings a lime based
mix is best. A stronger cement based mix is used in newer
buildings.
Brick Repairs
Defective bricks can be replaced or filled depending
on the
degree of damage.
Brick Cleaning
Pressure washing can remove most types of dirt,stains,
grease etc.
Bricks and mortar can be rejuvenated, enhancing the overall
look of the brickwork.
This environmentally friendly process requires no chemicals
or abrasive sand blasting
Brick Colouring
Most bricks can be coloured either lighter or darker
from the
original. New bricks can be blended to match existing.
Colour washing stains or problem areas should be avoided
as this only masks the problem for a short period.
Damproofing(Undersetting)
Older buildings tend to have a damp proof barrier(sand/asphalt)
this can break down over time especially where excessive
water saturation occurs. Once the barrier is breached rising damp
can result. In some cases where there is dampness in Winter and
dryness in Summer, staining or spalling to the brickwork can occur.
This is a serious problem should be addressed ASAP Undersetting
can rectify the problem. This process involves the removal of
defective bricks and a DPC(damp proof course) rolled out.
Completed in short stages a whole wall can be repaired without
the need to rebuild completely or inject silicon.
Render/Cement Removal
Render can be best removed manually. Power tools should be
avoided as the brick face is more likely to be damaged. Any
cement residue can be best removed using a weak acid wash.
All plant life should be protected or if possible replanted.
