Timberplus88 0 Report post Posted June 8, 2016 We have seen increasing problems arise from Wood Plastic Composite Decking(WPC) being installed in the past 3 years. As shown in the image above, they are ruptured due to material failure and not due to wear and tear. We received reports of those that collapsed in the planter balcony, while walking on, which mostly were installed back then in condominiums 3-4 years ago. if you have a deck like this, we will like to know more about it.
