Hello all

1850s victorian house. Dining room c35m2 has unknown UFH system screeded inbetween joists of suspended wood floor. Not sure about DPM (suspect not) but looks like 40mm screed on top of 60mm foil backed insulation board. Also no idea about relative humidity of base. Think it was installed around 8 years ago. We want to put down low tog underlay and 14mm oak engineered boards.

There is an area of c12m2 which has a dip/slope to the wall, focused in the area where the pipes run. Dips are between 2mm and 18mm deep. Some other minor patching required to level up to joists in other areas. Photos below.

Have read wiki but not sure on the best way to level or what products to use.

All thoughts welcome!

Check your intended flooring is compatible with ufh before you buy it.

Normally the pipes should not be visible and should be in the screed.
