1. A flooring plank comprising:
a core comprising at least 50 wt. % of calcium carbonate by weight;
a first wood veneer having a first grain direction and being affixed to a top surface of the core; and
a second wood veneer having a second grain direction and being affixed on top of the first wood veneer,
wherein the first wood veneer is placed between the core and the second wood veneer,
wherein the first grain direction and the second grain direction are substantially orthogonal with respect to one another, and
wherein the first wood veneer and the second wood veneer are substantially of a same species and thickness, such that the first wood veneer and the second wood veneer form a cross link to stabilize a warping of the flooring plank.
