Hi
I am planning on installing an engineered floor in my ground floor living room. The subfloor is of suspended wood construction, with wood jiost that i will cover in ply. There is a 3 feet void underneath, onto rough earth.
It is a little damp underneath and as part of the installation i will be improving airflow by introducing more air bricks at both ends.
There is a little damp smell down there and I am concerned about how to damp proof the floor. Should i seal the ply completely? Should i lay down a damp proof membrane? Do i need to align the damp proof course and the floor?
I have read conflicting advice, some saying you should seal completely and others saying you should leave air gaps so the floor can move and 'breathe'.
PLease help!
thanks
