Bathroom Waterproofing Canberra

Balconies are outdoor spaces that add to the liveability of a property. They combine the advantages of outdoor and indoor living, having light and fresh air in a neat, structured space. Of course, it is important to prevent water leaks and damage on a balcony, lest they cause problems for the rest of the building.

Why Waterproofing Matters

Balconies are exposed to the elements, making them susceptible to rain, sun, and temperature variations. Without proper waterproofing, water can seep into the structure, leading to issues such as concrete degradation, rusting of metal components, and potential damage to the interior spaces below.

Common Waterproofing Methods

Liquid Waterproofing Membranes

Applied as a liquid and forming a seamless, flexible barrier, these membranes are popular for their ability to adapt to various surfaces.

Sheet Membranes

Pre-manufactured sheets of materials like bitumen or synthetic rubber are applied to create a water-resistant layer.

Cementitious Waterproofing

Using a mixture of cement and additives, this method creates a waterproof barrier when applied as a thin layer on the balcony surface.

Surface Preparation


Before applying any waterproofing material, it’s essential to clean the balcony surface thoroughly, removing dust, dirt, and any existing coatings.

Crack Repair

Identifying and repairing cracks in concrete or other materials is crucial to prevent water infiltration.

Proper Drainage

Ensuring efficient drainage is essential to prevent water accumulation on the balcony surface. Proper slope design directs water away from the structure and towards drainage points.

Quality Materials Matter

Investing in high-quality waterproofing materials is a key factor in the effectiveness and longevity of the waterproofing system. Consider factors such as UV resistance, flexibility, and adhesion to the substrate.

Professional Installation

While some homeowners may opt for a DIY approach, professional installation ensures that the waterproofing system is applied correctly, covering all vulnerable areas and joints.

Regular Maintenance

Waterproofing is not a one-time task. Regular inspections and maintenance are essential to identify and address any potential issues promptly. This includes checking for cracks, inspecting drainage systems, and reapplying waterproofing materials as needed.

Consideration of Climate

Different climates pose unique challenges to balcony waterproofing. In areas with heavy rainfall, robust waterproofing measures are crucial, while in hot climates, UV-resistant materials become particularly important.
