Quick Answer
Tarred bankline can hold up against heavy rain, but its effectiveness depends on several factors, including the quality of the tar, the condition of the bankline, and the intensity of the rain.
Understanding Tarred Banklines
Tarred banklines are made from natural or synthetic fibers, coated with tar to provide protection against moisture and abrasion. The tar is typically applied in a specific ratio, usually 10-15% tar to 85-90% bankline. This ratio is crucial in maintaining the bankline’s integrity and water resistance.
Testing Tarred Bankline in Heavy Rain
To determine a tarred bankline’s ability to withstand heavy rain, a test can be conducted using a controlled environment. A section of tarred bankline is suspended in a rain simulator, where it is exposed to heavy rainfall equivalent to 100 mm per hour (3.9 in/h) for a period of 24 hours. The bankline’s condition is then inspected for signs of degradation or failure.
Maintenance and Inspection of Tarred Banklines
Regular maintenance and inspection of tarred banklines are critical in ensuring their effectiveness in heavy rain conditions. Inspect the bankline for signs of wear, such as fraying or cracking, and reapply tar as needed. Use a ratio of 10-15% tar to 85-90% bankline to maintain the bankline’s integrity. In extreme weather conditions, consider using a bankline with a higher tar content or applying additional coatings for added protection.
