Regular inspection of used tarpaulins is crucial to help identify worn materials that may require replacement over time. Tarpaulins are an essential piece of protective equipment used for covering and sealing various materials when transporting or storing goods outdoors. However, constant exposure to weather elements like rain, snow, sunlight, and abrasion can rapidly deteriorate tarpaulin materials if not properly maintained.
What parts of the tarpaulin should be inspected?
Not all areas of a tarpaulin will show wear at the same rate. Giving each section a close visual lookover helps gain a comprehensive understanding of any problem areas that need attention. The following components should be part of a standard used tarpaulin evaluation:
Top surface
Look for fading, especially of printed logos or identifiers that have lost color intensity. Inspect for small cuts, punctures, or thinning of the material. Feel for cracking or brittleness that reduces pliability.
Edges and corners
Being located at the perimeter, edges, and corners experience considerable abrasive stress from rubbing and catching during installation and use. Stitching pulled out or fraying along seams. Material tearing away from stitch lines. Impact damage or cracks at 90° bends.
Tensioning system
Straps, ties, and attachment buckles that keep the tarpaulin taut over time are high-wear components as well. For broken, cracked, or missing tensioning pieces. The straps/ties have not pulled through the fabric. Buckles and clips are intact and functioning properly.
Tips for extending the lifespan of tarpaulins
While eventual replacement is inevitable, following best practices can significantly prolong the usable life of tarpaulins:
Regular Cleaning
Regular cleaning removes surface dirt, grime, and contaminants that accelerate deterioration. Pressure wash tarps at least quarterly.
Prompt Patching
Prompt patching of defects like cuts or punctures prevents moisture ingress which often leads to mold growth and faster degradation. Use commercial vinyl patches rated for outdoor use.
Using tarps suitable
Choosing Heavy Duty Tarpaulin rated for the cargo weight, weather, and number of slit/grommet attachments expected extends life significantly.
Key signs that indicate a tarpaulin needs replacement
There are definite signs that indicate a used tarpaulin has surpassed reasonable repair and needs full replacement. Understanding these red flags helps determine when prolonged use poses unacceptable risks versus when minor maintenance still has benefits:
Number of years in service
As a general guideline, enclosed cargo tarps perform reliably for 3-5 years with proper care. Open-air tarps may last 1-3 years depending on exposure to elements. Once a tarp surpasses these timeframes, replacement is advisable even if minor defects remain. Advanced aging takes a bigger toll.
Percentage of original weight
New tarps have a set fabric weight listed on the specifications. Weighing used tarps and comparing to when new reveals loss of material integrity over time from drying/degradation. Over 30% reduction could signal replacement time.
Leak test results
Periodic leak testing with a hose or bucket of water applied to the top surface quickly exposes any pinholes or cracks that compromise waterproofing. Multiple or enlarging failures mean replacement versus patchwork.
D-Ring/grommet inspection
Checking that all attachment points can still bear rated weight loads is important for safety. Fatigued, cracked, or otherwise compromised fittings must be addressed even on an otherwise "good" looking tarp.
