Realistically, very few of us
have the time and resources to conduct careful examinations throughout the
construction or renovation of our home. While we like to think a job is
completed with competency, often proper sequencing and installation are compromised.
These flaws in construction can cause leaking and water seepage throughout our
homes, including our balconies.
Primary causes of a balcony leak:
Ceramic
tiles with few expansion margins
Well grouted ceramic tiles are
great however if there are a few expansion margins left between the joints, they
can be the cause of a balcony failure. The tiles, when exposed to heat, are
likely to expand, resulting in compression of the joints and causing tiles to
lift and leave entries for water. Poor installation of tiles with inadequate
expansion joints are a chief cause of balcony leakage.
Cracked
or missing grouting
Grouting is a key component of thorough
balcony construction. Cracked or missing grouting from corners and between
tiles can be detrimental to the structure of a building. Even a small crack in
the grouting can result in water seepage. A drenched balcony is likely to
absorb water through cracked or missing grouting. Grouting must not be
overlooked in construction, it is fundamental to the longevity of a structure.
Improper
slopes
The poorly thought out slope of a
balcony can cause water to pool, triggering a slow drip inside the structural
material. Subsequently, it compromises the waterproofing of the balcony and
increases leaking issues. When constructing a balcony, the slope must track away
from the building so that water can stay clear of joints.
Sealant
Sealants prevent water
infiltration and must be used on windows, doors, trims, flashing and more. Sealant
requires periodic inspection and maintenance to keep joints secure from water
infiltration. A quality sealant can last for 20 years, however, if not
maintained can be a major cause of leakage.
Flashings
Flashing is a form of
weatherproofing. According to building codes, flashings keep framing membrane
and sheathing uncompromised. Flashings play an important role in building
exteriors such as windows, doors, piping, joints, etc. Flashing is a sheet of
thin material which prevents water flow into the structure. No flashing = water
penetration and seepage.
