Timber Flooring Gone Bad

[MICKYG]

Gaza,

It looks as if all the flooring and joists are sitting on the soil underneath the building, drawing moisture up into the building. Your pictures does not show any sub structure IE: brick pylons etc unless it is all sitting on a concrete slab. Not a builder here but its just a guess.

Regards Mike.

You got any pics of these so called units, looks very odd to me...

Ok ok some good work there, alot of people on this forum have great know edge.
The flooring is installed in a new unit 1 of 125, all of which are in a same state.
These are the issues that we found on inspection;
- No moisture barrier and slab was over 5.5% MC
- pine battens used
- pine battens not fixed to slab with mechanical anchors at regular intervals, they were nailed to noggins which were then shot with a ramset gun.
- flooring was glued with ridge construction adhesive (ie max bond, liquid nails etc)
- no mid span expansion gap and width of floor is about 8mts
- while this unit did have windows and a slab above the roof on the complex was not complete so when it rained water leaked down though whole building
- flooring was Kiln Dried by a large manufacture. (not one of the best but ok)
- all the flooring is being ripped out and replaced cost of rectifying and completion a cool 1.2 million. Oops

So my No. 1 was right, but maybe not the others?
