We have a 2 bed victorian terrace and have exposed floorboards donwstairs. The kitchen extension has a solid concrete floor, rather than the suspended floor elsewhere. I'm about to install a new kitchen, but need to sort the floor out first. We want to install sanded and sealed reclaimed floorboards in the kitchen - I've thought about fitting them across "joists" laid on the concrete - using 25x38 section or similar pressure treated sawn timber for the joists. I don't know whether there is a damp proof membrane in the concrete floor so should I lay one before fitting the timers joists.
Any thoughts as to whether this is a good idea
thanks Charlie
