What if I have cracks in my concrete slab? Will that affect the floor heating installation?

Make sure any cracks or raised edges are sanded down before installation. Seal and patch cracks where possible. If needed, pour a layer of self-leveling cement to make sure surface is level and flat. Then proceed with instructions to install desired floor heating system and flooring.


It is strongly recommended that an insulating underlayment be installed between the slab and heating element to prevent heat loss.
