Avoid Costly Leaking Balcony Repairs

Leaking balconies can be a major problem in high rise apartment buildings, especially as they are constantly exposed to the harsh Australian climate. They require a lot of care and attention to keep them in good condition. If left unattended, a leaking balcony can result in significant damage that is expensive and disruptive to the building and its residents. Regular inspections of the balconies for Waterproofing service, pooling water, mold growth and other signs of moisture infiltration can help you identify issues early on and avoid costly repairs later on.

The reasons for balcony leaks are varied and can include construction defects, natural building movement and deterioration of the waterproofing membrane or tiles. Poor installation of the membrane during initial construction can lead to cracks that water can penetrate. This is due to incorrect surface preparation, inadequate bonding and the lack of expansion and contraction joints. The use of inappropriate materials for the balcony surface can also contribute to leaks. These factors can be minimised by ensuring the correct surface material is used and adhering to the manufacturer’s recommendations for the installation.

Poor drainage of the balcony can also contribute to leaking problems. If the surface is not adequately sloped to allow water to flow away from the balcony, it can pool and create a pressure point that will break down the membrane. Over time, this can cause water infiltration and structural damage to the balcony and surrounding areas of the building. Blocked drains are another common cause of pooling water on a balcony. Regular cleaning and unblocking of the drains is essential to ensure they are functioning correctly.

Water penetration from a leaking balcony can affect a wide range of surfaces and materials, including ceilings and walls. The resulting dampness can cause unsightly stains and discolouration, as well as mould growth that poses health risks to those who live in the affected areas. Moisture infiltration from a leaking balcony can also reach electrical outlets and wiring, creating potential safety hazards.

Traditionally, the process of repairing a leaking balcony involves stripping the existing tile and applying a new waterproof membrane and re-tiling the balcony. This can be extremely expensive, disruptive and take a long time to complete. A better alternative is to have a liquid applied membrane system installed. These systems are designed specifically for the Australian climate, and can be formulated to provide excellent waterproofing of the balcony without disrupting your living space. It is important to note that this type of solution cannot be guaranteed if the existing flashing is not replaced with new flashing to protect the balcony from rainwater infiltration. It is therefore important to have any leaking balconies repaired by licensed, professional waterproofing companies. In addition to replacing the flashing, a proper inspection and inspection of the balcony should be carried out to ensure that all the necessary components are secure and in good working order. This includes the drains, hobs, wall/floor joint, balustrade, water exit points, sheet joints and movement joints.
