FRP Frame Dry Seal Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional panelized wall assemblies face challenges with water and air intrusion at panel joints, which can lead to structural integrity issues and require labor-intensive wet seal waterproofing methods that are prone to errors.
Innovation Solution
The use of a dry-seal waterproofing system integrated into a composite frame assembly made from Fiber Reinforced Polymer (FRP) and high-performance fire-resistant flexible rubber, such as EPDM, eliminates the need for wet seals by providing a monolithic, efficient, and effective waterproofing solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wet seal waterproofing methods are used at panel joints, then waterproofing function is provided, but labor intensity increases and error susceptibility increases
Solution Approach 1:
The system employs self-sealing joints where the FRP panels themselves provide the waterproofing function through their inherent material properties and joint design, eliminating the need for separate wet seal applications. The panels automatically seal joints through their structural configuration without requiring manual intervention.
Solution Approach 2:
The patent extracts and eliminates the wet seal waterproofing layer from the assembly, replacing it with an integrated dry seal system where the FRP panels and their joints inherently provide waterproofing without requiring separate sealing materials or application processes.
2Strength
If traditional materials (concrete, steel, aluminum, wood) are used in panelized wall assemblies, then structural function is provided, but material degradation occurs compromising waterproofing
Solution Approach 1:
The patent employs Fiber Reinforced Polymer (FRP) composite materials that combine the structural strength of fibers with the protective properties of polymer matrices. This composite structure provides both the required structural function and inherent resistance to degradation, maintaining waterproofing reliability over time without the deterioration issues associated with traditional materials.
Solution Approach 2:
The invention changes the material parameters by transitioning from traditional degradable materials to FRP composites with superior durability characteristics. The FRP materials exhibit enhanced resistance to rot, corrosion, oxidation, and degradation while maintaining structural integrity, fundamentally altering the durability parameters of the building system.
3Ease of manufacture
If panelized wall assemblies are constructed with traditional materials and wet seal methods, then basic enclosure function is achieved, but construction time and maintenance requirements increase
Solution Approach 1:
The patent merges the structural function and waterproofing function into a single integrated FRP panel system. The FRP panels and their joints simultaneously provide both structural support and waterproofing, eliminating the need for separate waterproofing layers and reducing the number of construction steps required.
Solution Approach 2:
The FRP panels are manufactured with integrated waterproofing capabilities in advance, so that when assembled on-site, the waterproofing function is already built-in and requires no additional field application or sealing work, significantly reducing construction time.

AI summary
A frame assembly is constructed from a plurality of Fiber Reinforced Polymer (FRP) structural components and is configured to provide a dry seal at a joint between frame assemblies. The frame assembly comprises FRP C-channel structural components joined together with FRP corner connectors. The FRP C-channel structural components and the FRP corner connectors are designed to employ a flexible waterproofing material that provides a dry seal at the joint where the frame assembly joins to another frame assembly.
