Tape Mounting System for Foundation Coverings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in securing and sealing a covering, such as a vapor barrier, to a foundation wall in a crawlspace is exacerbated by the need for adhesives that do not emit high volatile organic compounds (VOCs) due to ventilation issues and the risk of fire hazards, while also requiring an instant bond for temporary installation and a permanent seal, which is difficult to achieve without mechanical fasteners or high VOC adhesives.
Innovation Solution
A tape mounting system with a porous substrate material featuring an instant bond adhesive on one side for initial mounting and an adhesive absorbing portion to receive a low VOC caulk adhesive that cures over time, providing an airtight and moisture-tight seal without mechanical fasteners, using a combination of instant bond adhesives on both sides for secure and safe installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If construction grade adhesives are used to secure the covering to the foundation wall, then the covering is securely mounted, but toxic fumes and flammable vapors accumulate in the crawlspace creating fire hazards
Solution Approach 1:
The adhesive system is segmented into two distinct parts: an instant bond adhesive for immediate secure mounting and a low VOC construction adhesive for permanent bonding. This segmentation allows the instant bond adhesive to provide immediate strength without the harmful VOC emissions of traditional construction adhesives, while the low VOC adhesive provides the permanent bond without fire hazards.
Solution Approach 2:
The invention changes the chemical composition parameters of the adhesive by selecting an instant bond adhesive with low VOC content and fire-retardant properties. This parameter change maintains the necessary bond strength while eliminating the fire hazard and toxic fume accumulation in the enclosed crawlspace environment.
2Object-affected harmful factors
If low VOC adhesives are used to eliminate fire hazards, then fire safety is improved, but the adhesive may not provide sufficient initial bond strength for installation
Solution Approach 1:
The adhesive system is divided into two functional segments: an instant bond adhesive that provides immediate high strength for installation, and a low VOC construction adhesive that provides permanent bonding without fire hazards. The instant bond adhesive's rapid setting property ensures sufficient initial bond strength while the low VOC adhesive maintains fire safety for the permanent installation.
Solution Approach 2:
The instant bond adhesive is applied first to provide preliminary bonding and immediate structural support, allowing the covering to be securely installed before the low VOC construction adhesive fully cures. This preliminary action ensures sufficient initial bond strength without compromising fire safety.
3Ease of operation
If mechanical fasteners are used to secure the covering, then immediate secure mounting is achieved, but the installation complexity and requirement for professional tools increases
Solution Approach 1:
The invention replaces the mechanical fastening system (screws, nails, drills) with a chemical bonding system using instant bond adhesive. This substitution eliminates the need for mechanical fasteners and professional drilling tools, significantly improving ease of operation and reducing installation complexity while providing immediate secure mounting.
4Quantity of substance
If the crawlspace remains open with vents for airflow, then moisture can be reduced through ventilation, but ambient air enters the crawlspace increasing temperature differential and energy consumption
Solution Approach 1:
The invention replaces the mechanical ventilation system (open vents) with a chemical/sealing system using the adhesive-bonded covering. This substitution creates an airtight seal that prevents ambient air infiltration, eliminating the need for continuous ventilation while controlling moisture through the sealed barrier, thereby reducing energy consumption from temperature differentials.

AI summary
A tape mounting system for a foundation covering having an adhesion strip including a porous substrate material. The porous substrate material having a wall adhesion side and a covering adhesion side facing opposite the wall adhesion side. An instant bond adhesive portion is included on the wall adhesion side and carries a first instant bond adhesive. An adhesive absorbing portion is included on the wall adhesion side that receives and absorbs an adhesive bead applied to a foundation wall. A second instant bond adhesive is disposed on the covering adhesion side for engaging a foundation wall covering. The instant bond adhesive on the wall adhesion side secures the adhesion strip to the foundation wall until the adhesive bead is cured to carry the foundation wall covering so that an air and moisture tight seal is formed between the foundation wall, the adhesion strip, and the covering material.
