Hi! Capacitive touch relies on conductivity and/or pressure (resulting in additional conductivity/completion of circuit). I’m not entirely sure how conductive concrete would be, as in whether it would complete a circuit through the concrete as a medium. Now, if there were a conductive pad on the underside of the slab and the control mechanism is of you pressing down on the slab, it could complete a circuit if the conductive pad were to touch another conductive pad. Hope that helps!

Will the touch work through 8mm thick concrete slab
