Considering engineered oak for the hall..

[dormermike]

Hi

Currently in the process of decorating our hallway, which is about 8 metres long and between 1 and 2.5 metres wide (opens out). As the bungalow has been chopped about over the years, the floor in the hall currently consists of the following surfaces (under the carpet / underlay).

Parquet blocks
Screed/cement surface
Terrazo (old kitchen or entrance way)

Have added a floor plan of the hall to demonstrate the distribution of the 3 surfaces.

There is minor damp at the base of some of the walls.

I was considering laying a DPM sheet over the floor (including parquet blocks) then putting the engineered boards over top.

Or should i rip up the parquet blocks (and terrazo?) and lay a new surface? Reluctant to do this for financial and mostly distruption reasons. Also the floor is reasonably level as it is at the moment.

The board I am considering is 21mm engineered, and is very stable.

Thanks
Mike

NEVER EVER install a DPM over parquet blocks! This will restrict the natural evaporation of moist in the concrete/blocks and will cause problems in the long run

How about painting a liquid dpm over the concrete and then using a foam (without DPM) underlayment over everything

Thanks. Thought there might be some issue like that.

Selective liquid DPM is a good idea.

There is minor damp at the skirting level near the parquet blocks.. not enough to rot them, but i could put some liquid dpm down there too i guess. I suspect its either rising damp (looong strong not going into it here) or possibly the front door/porch area water ingress.

Selective DPM it is.

Thanks again, nice one.

Wondering if I would be better ripping up the parquet blocks and screeding?
