Leaking Balconies

A balcony is an integral part of a house or apartment. To users, it renders a clear display of the outside world. In addition, it also provides a small sanctuary for shrubs and plants to blossom. Therefore, keeping it safe from water seepage or contamination (mold, mildew) is necessary and beneficial. Leaking balconies pose water damage risks; address promptly with waterproofing, repairs, and proper drainage solutions for protection.

Below, we will discuss some simple reasons as to why balconies possess a weak structure.

  1. Lack of Planning

Prior to construction, a company needs to address the issues of water ingress through chemical coatings. Preferably, cement-based liquid compound waterproofing system is used by experts. They understand the complexities involved in fixing balconies and possess the tools and equipment to manage work.

Balconies are exposed to different natural elements, such as rain or snow on a periodic basis, making the area susceptible to leaks, algae growth, and structural damage. Planning issues involve:

  • Incorrect selection of waterproofing materials
  • Incorrect installation of waterproofing products

There are various types of waterproofing products on the market, each with specific applications and features. If the wrong type of waterproofing product is used, it can result in a compromised waterproofing system.

Likewise, wrong installation of waterproofing chemicals or membranes can lead to issues like leaks, gaps, or crevices. It is advisable to connect with a waterproofing expert for optimal results.

  1. Limited Maintenance

Renovation or maintenance is an essential aspect to keep a structure intact and prevent moisture ingress. On the other hand, leaving the balcony unattended for long periods can lead to deterioration of the waterproofing system, buildup of debris or weeds, and damage to the drainage system.

Failing to maintain balconies or terraces can result in costly repairs and renovations. It is essential to have a maintenance plan in place to prevent issues, such as concrete rupture and spalling. Regular inspection and repair can help maintain the integrity of the waterproofing system and prevent significant damage from occurring.

  1. Improper Drainage

Foul drainage system can lead to serious problems for property owners. One common problem is inadequate slope. Leaking balconies should be sloped towards drainage outlets or scuppers to allow water to drain off the surface. If the slope is insufficient, water can accumulate on the surface, leading to leaks and water damage.

The location of drainage outlets can impact the effectiveness of the balcony’s surface. Outlets should be placed in locations that allow water to drain away from the building.

  1. Porous Surface

Masonry materials, such as grout, tiles, and concrete are not waterproof; water can easily seep through to the membrane. The surface needs to be water-resistant and safe from harm. A porous surface is difficult to maintain than a non-porous surface. Porous surfaces are more susceptible to discoloration and staining and require more frequent cleaning.

How to keep porous surfaces intact?

Porous surfaces used in waterproofing balconies require special care to maintain integrity and prevent water damage.

  1. Regular cleaning: Regular cleaning of porous surfaces is essential to prevent the buildup of dirt and debris. Experts recommend the use of mild detergent and warm water to clean the surface and rinse it with water.
  2. Avoid abrasive cleaners: Evade the use of stiff cleaners, such as wire brushes and scouring pads on porous surfaces. These materials can scratch the surface, making it more susceptible to water damage.
  3. Shun heavy objects: Don’t place heavy objects on porous surfaces because of cracks and damages to the surface.


Leaking Balconies is a common occurrence in residential and commercial settings. From reduced aesthetics to concrete damage, this problem can cause detrimental outcomes. Numerous reasons can affect the terrace’s surface, such as limited maintenance, improper drainage, and more.
