Good afternoon. I am building a 4×8 x21/4 single slab live edge pine farm table for my wife . The wood is approx 8% moisture as it sits in the shop . My question relates to radiant heat and this table . My house is heated with radiant floors with being stamped concrete of radiant floors in kitchen /dinning area. What can I do to prevent this table top from cracking via the heat and dryness of the floors ? Do I need to control the humidity in the space or would an expansion /contraction connection to the base work ? Or do I need both ? Thanks in advance .
