Adhesive Geotextile Patch for Silt Fence Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Silt fences at construction sites are prone to damage, leading to compromised integrity and reduced effectiveness in separating sediment and water runoff, which can result in clogged storm drains and environmental harm.
Innovation Solution
A silt fence patch comprising geotextile fabric with an adhesive layer and optional backing, designed to match the weave direction of the existing silt fence fabric, is applied to cover and repair damage, maintaining the integrity and functionality of the silt fence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silt fence is installed to separate sediment and water runoff, then environmental protection is improved, but the fabric is susceptible to damage from UV degradation, holes, and rips
Solution Approach 1:
The patent applies beforehand cushioning by providing a protective coating on the silt fence fabric that prevents UV degradation, holes, and rips before they occur. The coating acts as a protective barrier that cushions the fabric against environmental damage and mechanical stress, extending the service life and maintaining integrity of the silt fence.
2Reliability
If damaged silt fence sections are replaced, then integrity is restored, but labor and resource costs increase
Solution Approach 1:
The patent applies discarding and recovering by allowing the silt fence fabric to be reused after damage. Instead of discarding damaged sections, the fabric is recovered and repaired through patching with adhesive-backed patches that restore integrity. This extends the service life of the fabric and reduces the need for replacement, thereby reducing labor and resource costs.
3Reliability
If porous fabric is used to separate runoff, then sediment separation is improved, but fabric damage compromises separation effectiveness
Solution Approach 1:
The patent applies composite materials by combining the porous fabric with a protective coating and adhesive patches. The composite structure integrates the fabric's separation functionality with the coating's protective properties and the patches' repair capabilities, creating a multi-layered system that maintains both separation effectiveness and structural integrity.
4Area of stationary object
If silt fence sections are extended to cover more area, then coverage is improved, but the likelihood of damage increases
Solution Approach 1:
The patent applies segmentation by dividing the silt fence into smaller, manageable sections that can be individually protected and repaired. The adhesive-backed patches create segmented repair zones that can be applied locally to damaged areas without compromising the entire fence structure, allowing extended coverage while maintaining reliability through localized protection.
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 silt fence patch effectively restores the silt fence's ability to separate sediment and water, reducing the need for replacement sections and minimizing labor and resource costs, while ensuring continued sediment pond formation and runoff management.
Implementation Method 1

AI summary
A silt fence patch for repairing damage to silt fence is disclosed. A silt fence patch may comprise geotextile fabric, an adhesive layer, and a backing. The backing may include indicia of patches, such as patch weave direction, user instructions, or logos. A silt fence patch sheet may comprise multiple silt fence patches. The sheet may include a backing with indicia of each patch, or indicia of the patches may be printed directly on the sheet fabric. A method of repairing damage to silt fence may comprise identifying damage to the silt fence. A damage boundary may surround the damage. The method may further comprise identifying a patch size to cover the damage boundary. The method may further comprise selecting a patch having the identified patch size. Additionally, the method may comprise applying the selected patch to the damage boundary and smoothing the patch over the damage boundary.
