Shrink Wrap Containment for Bridges & Infrastructure Projects
Jul 21st 2025
What Is Shrink Wrap Containment?
Shrink wrap containment uses heat-shrunk, flame-retardant polyethylene film to fully encapsulate structures during maintenance, repair, or construction. Once heated, the film contracts tightly over scaffolding or structural elements, creating a sealed, weather-resistant barrier.
Why Use Shrink Wrap on Bridges & Infrastructure?
Superior Weather and Contaminant Protection
- Creates weatherproof enclosures that allow crews to work in rain, wind, or snow.
- Supports environmental safety by capturing paint dust, grit, lead, asbestos, and other debris during blasting or painting.
- Offers visual shielding to reduce public exposure and enhance safety around active job sites.
Exceptional Stability and Durability
- Bi-axially shrunk film tightly conforms to complex structures, minimizing movement from wind and eliminating sagging.
- Fire-retardant certifications like NFPA 701 and ASTM E84 ensure compliance for work near lighting or welding.
Faster, Cleaner, and More Productive
- Speeds up project timelines by reducing weather delays and eliminating the need for rework common with traditional tarps.
- Allows multiple crews to work safely and simultaneously within a clean, contained space.
- Shrink wrap material can be recycled post-project when kept clean and uncontaminated.
Typical Applications in Bridge & Infrastructure Work
Bridge Girders & Underside Refurbishment
Encapsulates scaffolding beneath bridges to prevent falling debris and protect waterways or traffic areas during sandblasting, repainting, or restoration.
Abatement (Lead, Asbestos, Paint)
Provides a sealed, Class-1 enclosure to safely contain and control hazardous materials, essential for projects near populated areas or sensitive environments.
In-Line Coating & Concrete Repairs
Creates controlled, dust-free environments necessary for specialty coatings or curing concrete without contamination.
Temporary Roofs & Elevated Structures
Used to construct temporary shelters or overhead containment around bridge spans or high-access repair zones.
Key Benefits at a Glance
| Benefit | Description |
|---|---|
| Weather Resilience | Enables dry, controlled workspaces in adverse weather |
| Containment Integrity | Seals tightly to prevent debris or contaminant escape |
| Wind Resistance | Resists uplift and movement better than tarps |
| Fire Safety | Certified for use in high-risk environments |
| Efficiency Gains | Faster setup, fewer delays, improved productivity |
| Recyclability | Clean wrap can be recycled after use |
Installation Best Practices
- Site Prep & Scaffold Design
Ensure scaffolding is designed to support tensioned film and additional loads. - Film Application & Heat Shrink
Wrap surfaces, heat seal seams, and shrink for a tight, weather-resistant fit. - Access & Ventilation
Include zipper doors and vents for safe worker access and air circulation. - Quality Checks
Inspect welds, seams, and tension. Patch any punctures immediately. - Dismantle & Recycle
After project completion, remove the wrap carefully and recycle when possible.
Best Use Scenarios
- Bridge repainting and blasting containment
- Structural beam and deck repairs
- Environmental abatement of lead or asbestos
- Corrosion protection in marine or wet zones
- Temporary weather shelters for emergency work
