TPU in building waterproofing: performance and sustainability

14/02/2025
Thermoplastic elastomers

In the construction sector, waterproofing is a crucial element to ensure the durability and safety of buildings. Among the most innovative materials in this field, thermoplastic polyurethane (TPU) stands out for its excellent technical performance and reduced environmental impact. Thanks to its chemical resistance, elasticity, and long lifespan, TPU is an effective and sustainable solution compared to traditional materials such as PVC and bitumen.



Technical features of TPU for waterproofing
TPU offers a combination of properties that make it particularly suitable for building waterproofing applications. Its high chemical resistance protects it from corrosive agents, oils, and solvents, ensuring greater durability of the structures in which it is used.

Another key characteristic of TPU is its elasticity and flexibility, which allow it to easily adapt to surfaces while maintaining its integrity even at low temperatures, thereby reducing the risk of cracks and fractures over time. Its molecular structure also makes it completely waterproof, creating an effective barrier against water and moisture and preventing harmful infiltrations.

Finally, its high resistance to wear and UV rays ensures superior durability, reducing the need for maintenance and replacement over time.


Advantages of TPU over traditional materials

Compared to alternatives like PVC and bitumen, TPU offers several competitive advantages:

  • Longer lifespan: TPU has a longer service life than PVC and bitumen, which tend to degrade more quickly due to exposure to atmospheric agents.
  • Better adhesion to various surfaces: TPU can be applied to different substrates, ensuring perfect adhesion without the need for primers or complex pre-treatments.
  • Ease of installation: as a thermoplastic material, TPU can be hot-welded, simplifying installation processes and reducing working time.
  • Safety and absence of harmful emissions: unlike bitumen, which can release toxic fumes during application, TPU is a safe material that does not emit harmful substances, making it ideal for sensitive environments such as hospitals and schools.

Reduced environmental impact with recycled TPU
One of TPU's strongest points is its recyclability, making it a sustainable choice for the construction industry:

  • Waste reduction: TPU can be recovered and reused, contributing to the reduction of plastic pollution and supporting the circular economy.
  • Lower environmental impact in production: compared to PVC, TPU production requires fewer energy resources and reduces CO₂ emissions.
  • Replacement of non-recyclable materials: the use of recycled TPU in waterproofing membranes helps limit the consumption of virgin materials, reducing dependence on fossil resources.

Conclusion

The adoption of TPU in building waterproofing represents a technologically advanced and environmentally responsible solution. Its superior performance, combined with its recyclability, makes it a strategic choice for companies aiming to offer innovative and sustainable products. Investing in TPU means improving construction quality, reducing environmental impact, and aligning with the growing sustainability regulations in the building sector.
