Basement Edging with Segmented Channels for Radon and Water Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional basement waterproofing systems are inadequate as they allow soil gases to vent into living areas, creating radon and mold issues, and often create air gaps that lead to structural problems and high volumes of water leakage through seams, which can result in floor settling and foundation issues.
Innovation Solution
A basement edging system with a horizontally-extending bottom portion, a vertically-extending top portion, and an angled intermediate section that directs water from the foundation walls into a drainage conduit, minimizing air gaps and incorporating overlapping tongues for enhanced sealing, formed from plastic for efficient water routing and vapor barrier integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wall drainage products are used to direct water into the sub-floor drainage system, then water drainage function is improved, but soil gases vent into the living area causing radon and mold issues
Solution Approach 1:
The edging is divided into multiple segments that can be joined together to form a continuous barrier. Each segment contains integrated channels that separate water flow paths from gas venting paths, allowing water to be directed into the drainage system while gases are routed through dedicated pathways away from the living area
Solution Approach 2:
The edging acts as an intermediary structure between the foundation wall and the sub-floor drainage system. It includes integrated vapor barriers and sealed channels that mediate the interaction between water and gases, directing water into drainage conduits while preventing soil gases from entering the living space through sealed pathways
2Ease of manufacture
If conventional systems create an air gap between the footing and the floor and between the floor and the wall, then installation simplicity is improved, but structural integrity deteriorates leading to floor settling and foundation wall pushing inward
Solution Approach 1:
The harmful air gap is extracted and replaced by the edging structure. The edging is embedded into the concrete floor and extends down to the footing, eliminating the air gap while maintaining installation simplicity through its integrated design that combines the functions of a barrier and a drainage interface
Solution Approach 2:
The edging merges multiple functions into a single structure: it provides a physical barrier to soil gases, creates a sealed interface between the floor and foundation, and integrates drainage channels. This eliminates the need for separate components and the problematic air gap while maintaining ease of installation
3Adaptability or versatility
If conventional edging uses seams between adjacent sections, then manufacturing and installation flexibility is improved, but water leakage increases with high volumes of water passing through approximately 20 to 50 seams
Solution Approach 1:
The edging segments are designed with overlapping configurations and integrated sealing mechanisms that are built into the structure before installation. The overlapping tongues and grooves are pre-formed to ensure watertight connections, eliminating the need for separate sealing operations and preventing water leakage through the joints
Solution Approach 2:
The edging is formed from composite materials or multi-layer construction that includes integrated sealing layers and waterproof materials. This composite structure provides both the flexibility needed for installation and the reliability to prevent water leakage through the seams
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The edging system effectively routes water into drainage conduits, reduces radon and mold infiltration, enhances structural integrity by eliminating air gaps, and minimizes seam leakage, thereby improving indoor air quality and preventing structural failures.
Implementation Method 1
The intermediate section can span in a straight line and intersect each of the vertical plane and the horizontal plane at an oblique angle

AI summary
A water drainage edging segment includes a horizontally-extending bottom portion, a vertically extending top portion, and an angled intermediate section spanning between the bottom and top portions. The bottom portion defines a plurality of longitudinally spaced bottom channels that are oriented at one or both of a perpendicular angle and an oblique angle to the longitudinal axis of the edging segment. Each of the plurality of bottom channels are raised above a lowermost plane of the bottom portion to define an open passageway from a backside of the edging segment and laterally through the edging segment. The top portion defines a longitudinally extending upper rib portion that projects rearwardly from a front plane of the top portion to define a forward offset of the front plane and an upward facing contact surface.
