Traditional waterproofing systems are designed to keep water out. However, completely sealing a surface can sometimes trap moisture inside building materials, leading to long-term damage.
Breathable waterproofing takes a different approach. It helps prevent water penetration while allowing moisture vapor to escape naturally from the structure.

Breathable waterproofing systems help to:
They are commonly used on concrete, brick, natural stone, and other porous building materials.
Breathable systems reduce the absorption of liquid water without blocking vapor diffusion.
This allows moisture already present within the material to evaporate naturally, helping walls and structures dry while reducing the risk of trapped moisture.
When moisture cannot escape, a variety of problems can develop over time:
For this reason, moisture management is often just as important as protecting a structure from external water.

Many moisture problems occur because the wrong waterproofing system is selected.

Buildings exposed to frequent rainfall, humidity, groundwater pressure, and ongoing moisture movement often experience problems when non-breathable waterproofing systems are used.
Common issues include:
Breathable waterproofing systems such as Logic EX are often used to reduce water absorption while still allowing moisture vapor to escape.
This helps support natural drying, reduce moisture-related damage, and improve the long-term durability of façades and building materials.
Hydrophobic protection and breathable waterproofing often work together.
While hydrophobic treatments help reduce water absorption, vapor permeability remains intact. This allows building materials to stay dry while continuing to release trapped moisture.
Not every waterproofing system is suitable for every structure. For concrete, brick, stone, and other porous materials, vapor permeability often plays a critical role in long-term performance.

A waterproofing system that helps repel water while allowing moisture vapor to escape from building materials.
It helps prevent trapped moisture and supports the natural drying process of walls and building materials.
Yes. It is commonly used on concrete, brick, natural stone, and other mineral-based building materials.
Yes. It is widely used to protect façades from moisture while maintaining vapor permeability.
Breathable waterproofing helps protect structures from water while supporting the natural drying process of building materials.
By combining water repellency with vapor permeability, it can help reduce moisture-related damage and improve the long-term durability of buildings.
