What are the structural considerations of wood & butcher block countertops

Many people are familiar with a wood surface in the form of a table top or piece of furniture. Most of these, even very high end pieces, are made of laminated plywood and veneer. This is done because it is very structurally stable, meaning it moves little in changing climates. A solid wood counter is different. It is made up of large volume planks of wood that can expand and contract up to a ¼” throughout the year. This can causes glue joints to have very slight texture and can cause a top to warp if it’s not properly sealed and secured to its base. These are all natural movements which don’t compromise the structure or durability and are not to be considered defects in the top.
