A method of manufacturing a sacrificial limb for a deck plank provides a deck plank that is comprised of a wood replacement material. The deck plank has a tongue that is adapted to fit with a groove of an adjacent deck plank. A channel is cut in the tongue of the deck plank. The channel is adapted to induce the tongue to fracture when expansion of the wood replacement material causes sufficient pressure between the tongue and the groove of the adjacent deck plank. As a result, expansion and contraction of the deck plank material preferably does not cause the deck to buckle.
