EPDM liners are generally resistant to both folding and creasing while still maintaining flexibility and durability. If an EPDM liner is folded or creased, it may develop weak spots or stress points where damage can develop over time. To prevent this, EPDM liners should be laid flat and unfolded as much as possible during installation. If the liner needs to be folded or creased in order to fit a specific area or contour, this should be done as gently as possible.
Some EPDM liners may arrive pre-folded or creased for shipping or storage purposes. In this case, it's essential to follow the manufacturer's instructions for unfolding and installing the liner to ensure that it does not take any damage.
