8. Life Cycle
What is the expected life cycle of your product under normal use.
The warranty of the sheet piling is a 50-year pro-rated warranty. Since the PVC is an inert
material, we expect the product to perform even longer.
Have you performed any test to establish this life cycle.
I don't believe so.
Do you have any data to establish this life cycle without test.
No. However, we have based this believe on the 56 years of manufacturing thermo-plastic
9. Degradation of properties over time:
Have you established any change with time in compressive strength, tensile strength and
shear strength of the material constituting your vinyl sheet pile products by exposure to
out door conditions (sunlight). If so, what is the rate of change?
We have not specifically tested for any long-term properties with time except for creep. Many
industry studies on mechanical strengths vs. UV exposure time have been done using
standard weatherable rigid PVC compounds. These were referenced in the development of C-
Loc and repeating the tests was not deemed necessary. One example is a 1993 study done at
BF Goodrich, one of the world leaders in rigid PVC manufacture and research. Please see
attached BF Goodrich study and Elf Atochem study for reference.
