Advantages and Disadvantages of Polyurethane WaterproofingAdvantages and Disadvantages of Polyurethane Waterproofing

Polyurethane waterproofing is an important component of any project involving the construction or renovation of buildings. Waterproofing protects erected or ready-made structures from moisture penetration, thus increasing their reliability and saving money on restoration costs in the future.

Various materials are used for waterproofing, but it is essential to understand that each material has its advantages and disadvantages. The decision of what kind of waterproofing to choose will primarily depend on the criteria that are specific to your project. The most popular options include sheet membranes and liquid-applied products. Both options have their own unique advantages and disadvantages, but the best option is a waterproofing system that offers both durability and flexibility.

The Science Behind Polyurethane Waterproofing: How It Works

Polyurethane waterproofing is the ideal choice for projects that require a high level of flexibility. Unlike other materials, such as thermoplastic membranes, PU does not suffer from deterioration when exposed to high temperatures for an extended period or in contact with certain oils and greases. In addition, it is also easy to install and can be used for both new construction as well as renovation works.

Another advantage of waterproofing with PU is that it is environmentally friendly. It does not release volatile organic compounds (VOC) and is available in low-VOC variants, making it a good choice for any environment. Moreover, it can be easily recycled after use and does not damage the surface.

If you are considering using a polyurethane waterproofing system, you should know that the proper preparation of the substrate is crucial to the success of the application process. For example, the surface needs to be free from dust, dirt, oil and grease. It is also important to make sure that the structure of the substrate is solid and that no cracks or holes are present.
