Hello fellow homebuilders,
My wife and I have found a charming older bungalow (built in 1985).
We are currently still negotiating the finances, but things are looking promising.
Since I want to contribute as much of the work myself as possible, I have been planning back and forth for months. At first, we wanted to keep the old floor and install regular radiators. However, I have changed my mind and would now like to install underfloor heating, if feasible.
At the moment, there is a kind of concrete floor, about 12cm (5 inches) thick, with what appears to be rubble and sand underneath. Typical for former East Germany.
I plan to completely remove the floor throughout the entire 100 m² (1,076 sq ft) apartment and install a new one. The reasons are, first, to install underfloor heating, and second, to level out several floor steps that I would like to make even.
I have already read a lot and asked around, but so far I have not reached a clear conclusion.
So here is my question:
What would be the most sensible floor construction? Remove all rubble and sand, add new, dry sand for leveling, install a thick PE foil and insulation boards, pour about 4cm (1.5 inches) of concrete on top, install the underfloor heating, and then pour a heated screed? In the end, tiles will be laid in the bathroom and kitchen, and laminate flooring in the rest of the apartment.
Do you recommend other floor build-up options? No heated screed, rather flowable screed? Something else instead of concrete as a subfloor? Special insulation options?
Thank you very much for your input.
Best regards,
Andy
