What are Heavy Duty Poly Tarps?
Heavy-duty poly tarps are protective coverings made from polyethylene (PE). They are woven and/or laminated to increase tear resistance and waterproofing. Typical uses include construction, boat and vehicle covers, emergency shelters and outdoor storage.
Why Choose Heavy Duty Poly Tarps?
- Durability: Thicker mil ratings resist tears and punctures.
- Waterproof: Laminated poly tarps are highly water-resistant.
- UV Protection: UV coatings extend outdoor lifespan.
- Cost-effective: Less expensive than canvas or vinyl for similar coverage area.
- Lightweight & versatile
Factors to Consider When Choosing a Tarp Size
Measure the area you need to cover and add 10–20% overlap to ensure full coverage. Use straps or bungee cords through grommets to keep it secure.
Thickness (Mil)
Common mil ranges:
| Mil | Best for |
|---|---|
| 5–7 mil | Light-duty: camping, temporary covers |
| 8–10 mil | Medium-duty: vehicles, general outdoor projects |
| 12–14 mil | Heavy-duty: construction, long-term storage |
Material Type: Woven vs Laminated
Woven tarps have a fabric-like weave for tear resistance. Laminated tarps add a plastic film for superior waterproofing. For wet climates, prefer laminated.
Grommets & Reinforced Edges
Look for metal grommets spaced every 18–24 inches and double-stitched or taped edges to prevent tearing at stress points.
UV Resistance
UV coatings prevent plastic degradation. If the tarp will be in direct sun for months, pick a tarp specifically labeled UV-resistant.
Top Uses for Heavy Duty Poly Tarps
- Construction Sites: Cover materials and create temporary roofs or walls.
- Vehicle Protection: Cars, boats, RVs—choose UV-resistant options.
- Agriculture: Cover hay, equipment, and supplies.
- Outdoor Storage: Furniture, tools, and firewood protection.
- Emergency Shelters: Fast coverage for disaster relief or temporary housing.
- Camping: Ground cloths or shelter canopies.
How to Care for Your Poly Tarp
- Clean with mild soap and water; avoid harsh solvents.
- Store in a cool, dry place away from direct sunlight when not in use.
- Inspect for holes and repair with patch kits or heavy-duty tape.
- Avoid dragging over sharp edges.

Frequently Asked Questions
Q: Are poly tarps breathable?
A: No — standard polyethylene tarps are not breathable. If ventilation is required, consider mesh or tarps with vents.
Q: Can I use heavy-duty tarps as emergency shelters?
A: Yes — they offer fast, waterproof protection. Reinforce anchor points to resist wind.
