Choosing the Right Waterproofing Membrane for Terraces and Balconies

Aug 17, 2024

One heavy rain and your terrace or balcony starts showing signs of water damage. This causes nuisance for the residents, and if not managed with the appropriate waterproofing membrane, it can lead to serious safety issues such as cracks, loosening joints, beams, and more.

Given the number of waterproofing membranes in the market, each designed to address a specific water damage problem, selecting the right solution can be time-consuming. Whether liquid-applied method or cementitious-based water proofing for terraces, each offers unique benefits and treatments.

In this guide, we’ve compiled a list of factors to consider when choosing the best waterproofing chemical for terraces or balconies, successfully meeting your requirements.

Choosing the Right Waterproofing Membrane for Terraces and Balconies

1. Consult a Professional

Before beginning your project consult with an experienced professional. They will help you determine and evaluate your building’s material requirements. This step ensures you’re on the right track and making an informed choice.

2. Know the Building’s Construction

Understanding the building’s architecture and site circumstances is critical to selecting suitable water proofing for terraces and balconies:

  • Construction: Determine whether the region is above or below ground level. Consider the surface to which the waterproofing will be applied (concrete, masonry, etc.), the presence of drainage systems and the need for shotcrete applications.
  • Site Conditions: Check the water table level and probable hydrostatic pressure. Determine the presence of polluted soil vapour or gasses that may affect the waterproofing membrane’s performance.

3. Selecting the Right Waterproofing Membrane

Once you have considered the above factors, it’s time to understand the different types of balcony and terrace waterproofing membranes:

  • Liquid-applied: They are flexible and easy to apply, suitable to fill irregular surfaces in terraces and balconies. They provide a seamless barrier against water penetration.
  • Cementitious: Made of cement and polymers, they attach effectively to concrete and masonry surfaces. They are flexible and crack-resistant, appropriate for positive and negative water proofing for terraces and balconies.
  • Polyurethane: Known for its durability and flexibility, it can withstand substrate movement and temperature fluctuations. They are highly resistant to water and UV exposure.
