Besttarpaulins Hidden Problems You Should Know
While a sturdy tarpaulin is an essential tool for countless jobs, from construction sites to garden storage, not all tarps are created equal. Many users, lured by a low price point, encounter frustrating and costly problems down the line. This guide uncovers the common hidden issues with subpar tarpaulins and provides a practical, step-by-step approach to selecting a truly reliable product, ensuring your assets are properly protected.
Material Flaws and Premade Weak Points
The most common hidden problem lies in the material quality itself. Cheap polyethylene tarps often use a low-grade virgin or even recycled plastic mix that becomes brittle with prolonged UV exposure. This leads to cracking, especially along the folded seams and around the grommets. These are premade weak points where stress is concentrated. A quality tarp from a reputable supplier will use high-density polyethylene (HDPE) or laminated fabrics designed to resist ultraviolet degradation for significantly longer.

Grommet Failure and Reinforcement Issues
Grommets are the Achilles’ heel of many tarps. Inferior products feature poorly installed metal or plastic eyelets that pull away from the material under moderate tension. The key is to look for reinforced grommets. This means the grommet is not just punched through the single layer of tarp material but is set into a double-layer of fabric or a specifically reinforced hem. Without this, even a slight wind can rip the grommet out, rendering the entire cover useless and potentially causing damage as it flaps loose.
Inadequate Waterproofing and Seam Leakage
Assuming your tarp is fully waterproof is a common mistake. Many lightweight tarps are only water-resistant and will eventually allow moisture to seep through under sustained rainfall. The true test is not the centre of the tarp but its seams. Heat-welded or ultrasonically sealed seams are far superior to stitched seams. Needle holes from stitching create a pathway for water, which is why stitched seams must be covered with a waterproof tape. Cheaper models skip this taping process, guaranteeing leaks.
| Problem | Cause | Solution |
|---|---|---|
| Grommet Pull-Out | Lack of reinforced hemming | Choose tarps with double-layered hems at all stress points. |
| Seam Leakage | Stitched seams without tape | Opt for heat-welded seams or taped stitched seams. |
| UV Degradation | Low-grade polyethylene | Select HDPE or canvas tarps with UV inhibitors. |
| Mildew & Rot | Non-breathable material trapping moisture | Use breathable fabrics like canvas for long-term storage. |
Step-by-Step Guide to Selecting a Quality Tarpaulin
To avoid these hidden problems, follow this checklist when making your purchase:
- Define the Purpose: Is it for short-term transport, long-term outdoor storage, or heavy-duty construction? This dictates the material weight (e.g., grams per square metre or mil thickness).
- Check the Material & Fabrication: Feel the material. It should be supple, not stiff and brittle. Inspect the seams—are they taped or welded? Look for reinforced corners and hems.
- Test the Grommets: Tug gently on a grommet. It should feel securely anchored with plenty of extra material around it, not like it’s about to tear free.
- Review Specifications: Look for keywords like “UV-treated,” “rot-proof,” “rip-stop,” and “100% waterproof.” These indicate better construction.
Understanding the True Cost of a Cheap Tarpaulin
The initial savings on a low-cost tarp are often illusory. A £10 tarp that fails after one season and ruins £500 worth of stored timber is a false economy. Investing in a heavier-duty, properly manufactured tarpaulin from the outset saves money, time, and frustration in the long run. The cost isn’t just the price of the cover; it’s the value of what you’re protecting beneath it.
