Cascade Hydro Isolation Barrier for Massive Wall Rehabilitation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for rehabilitating old buildings affected by capillary moisture, such as those described in previous patents, face challenges in connecting multiple levels of horizontal hydroisolation without compromising structural integrity or causing settlement and cracking, especially in massive walls with varying floor levels.
Innovation Solution
The Plastic Profiled Semi-Rigid Barrier No. 3 enables easy and safe cascade connection of different levels of horizontal hydroisolation by using vertically cut barriers with optimized rib heights and a unique coupling mechanism, ensuring the barriers can withstand vertical loading without deformation and preventing capillary moisture penetration.

1Object-affected harmful factors
If horizontal cuts are made to install barriers in massive walls, then capillary moisture penetration is prevented, but the structural integrity may be compromised and settlement cracking may occur
Solution Approach 1:
The barrier system is divided into multiple segments (first barrier, second barrier, third barrier) installed at different levels. Each barrier is installed in separate horizontal cuts at different heights in the wall, allowing the moisture protection function to be distributed across multiple locations rather than requiring a single deep cut that would compromise structural integrity.
Solution Approach 2:
The solution transitions from a single horizontal barrier to a multi-level cascade system adding the vertical dimension. By installing barriers at multiple vertical levels (different heights in the wall) and connecting them through vertical joints, the system achieves effective moisture blocking without requiring any single cut to be deeply penetrating, thus preserving wall stability.
2Adaptability or versatility
If multiple levels of horizontal hydroisolation are installed to adapt to different floor levels, then adaptability to varying floor levels is improved, but the complexity of connecting these levels increases
Solution Approach 1:
The cascade connection system is segmented into modular components: horizontal barriers at different levels and vertical connecting barriers. Each component has a standardized structure with coupling elements that simplify installation. The segmentation allows independent installation at each level followed by simple vertical connection, reducing overall system complexity compared to a monolithic multi-level structure.
Solution Approach 2:
The barrier components are designed with universal coupling mechanisms (coupling elements with coupling holes) that can connect barriers both horizontally and vertically. This multi-functional coupling design allows the same basic component structure to serve multiple purposes: forming horizontal barriers at different levels and connecting them vertically, thereby simplifying the cascade connection process.
