A simple leakage in a building roof can often result into serious problems, not only cause damage to the building’s structure but can also be very expensive to fix. When dealing with high-rises or larger commercial buildings, replacing or reconstructing a damaged roof is not always feasible or practical.

Leaks can be mended with efficient waterproofing techniques done by a professional waterproofer. Waterproofing ensures that water cannot penetrate through the roof of the building. The best and most cost-effective solution is prevention. Through durable sealing and applying of waterproof coatings, water intrusion can be prevented, eliminating water damage.

There are many factors that should to be considered when determining the best roof waterproofing solution. If in doubt, it is best to consult with a roof waterproofing expert who will know the most effective waterproofing method to use for each application.

Among the types of waterproofing solutions, Sheet membranes and Liquid membranes are mostly used for implementing water protection for roofs.

Let’s take a closer look at these two waterproofing methods.


Using high quality adhesive, sheet membranes may be cold applied or with the help of a torch. When done right, sheet membrane provides a durable and long-lasting waterproofing solution.

Sheet membranes are good to apply to almost all horizontal areas that require waterproofing. They are usually high performance and non-hazardous.


Liquid membrane waterproofing delivers an excellent waterproofing solution that is applicable to small or very detailed areas on which sheet membranes are harder to use. This type of membrane is ideal for wet areas, it very easy to apply, resistant to UV rays and not harmful to the environment.

A great advantage of using liquid membranes is that it creates a fully bonded, protective seal, this ensures that no water will enter beneath the membrane.
