What is a Leaking Balcony?

Balconies and terraces have the highest number of waterproofing failures, according to insurance figures. Although many of these constructions' design standards fail to account for water control, not all leaky balconies are the result of a faulty waterproofing membrane. Balconies that leak can have severe consequences. if not adequately assessed or planned for, and should be a source of concern for any homeowner  Most balconies leak eventually. When the original design was created, the best materials were chosen, but the building process and changes in weather may cause leaks.

Many balconies, particularly in multi-level buildings, are built with modest falls to the ground. If the waterproofing membrane employed is inadequate to handle ponding water. A balcony with a low fall is prone to water accumulating and moisture between the membrane and the tiles, a situation known as "ponding."

When you waterlog a basement, the dampness in the soil surrounding the foundation can cause the foundation wall to rot and eventually collapse. This is called wet-rot or root-boundary decay. In the past, you would typically see water under the slab and along the top of the foundation wall.

How Do You Know if You Have a Leaky Apartment Building?

The damage often isn't as severe as the term implies. Water entering behind the cladding doesn't always mean that the home needs to be torn down. In many cases, the cladding itself can be repaired, and the home can continue to function.

When water is added to a substance, it expands and cracks appear. That's why windows and cladding need careful scrutiny when looking for signs of moisture damage. If cracks or any other damage is found, be sure to contact your insurance company to get your coverage back on track.

How to Prevent Future Problems with Leaky Balconies in Your Own Apartment Building

Balconies are prone to water seepage due to their frequent exposure to the weather. Each balcony is built differently, and the risk of water penetration increases if waterproofing measures do not accommodate the balcony design. Balconies require sufficient drainage and isolation from the internal elements of a apartment, as well as the installation of the proper waterproofing membrane to prevent leaks. Waterproofing failure is typically caused by an unskilled contractor, bad membrane selection, or a homeowner or contractor attempting to save money.

If you have a leaky balcony, the first thing you should do is do a comprehensive inspection and evaluation to discover any anomalies or maintenance difficulties.  If you pour water on the tiles and find some leakage, this indicates that the membrane has been breached/failed, enabling water to flow through. Other things to keep an eye out for are:

  • Grout that is cracked or missing.
  • Water stains on the balcony's underside or the inside ceiling.
  • There are issues with opening and closing the balcony doors.
  • Paint that is peeling or splitting.
  • The balcony railing and pillars have weak structural joints.

If you suspect that your balcony is leaking, the greatest part you can do is hire professionals to come out and assess the situation to determine the cause of the problem. They can tell if any of the conditions listed above apply, or if the membrane has failed.
