Flooring Help

[pantotango]

We are looking at building a floor which unfortunatley due to flood levels cannot be slab on ground so just wondering what is one of the easiest and cost effective ways to go. I was thinking of chipboard then tiling later on or would it be cheaper to go for straight wooden flooring on top of the framing.

If you are in a flood prone area...I would advise you do not use chipboard flooring. It is not designed for cope with total immersment in water!

You can get cement sheeting as a flooring product. This is stuff is designed for wet area use and would cope very well if its immersed in water.

Timber floor boards are a very expensive floor finish. They look great, but will cost you. Chipboard with tiles will be cheaper, but keep in mind the issue that jimc mentioned. The fibro sheeting is probably a good idea. Best to check with a local professional or council though

Can I ask why not?

If you are building in a 'designated flood prone area' your council will stipulate the minimum height above ground level that your floor level must be.
As with any timber flooring systems, subfloor cross ventillation is important
Either strip flooring or platform flooring will be fine with the choice coming down to do you want polished boards or are you looking at carpeting.

If I was building in a designated flood prone area (no way Jose!) I would go suspended slab with tiled floors. That way if it does ever flood higher than usual you won't get any structural or cosmetic damage to your floor.

Some 'designated flood prone areas' i've come across can require floor levels over 700mm above ground level. Thats a lot of suspended slab Mick!

Well, I guess in that case I'd be building a highset about 2.7 - 3M off the ground. I know that budgets can be tight but I'd rather do without other things for a few years than build a lowset house with timber floors in a floodprone area.

In my local area we are part of the cities flood plan.

All existing properties are allowed to build to current floor height, we are, we did and we are screwed if it does flood. Such is life + what are the chances? 1 in a 100 years perhaps.
From what i can gather all new dwellings in our area are subject to a 1.7 - 2.4m pad height so that they comply with the flood plan.
Doesnt make for good relations with neighbours i think.

i stand corrected........a flood last occurred in 1982 and it took a cyclone to make it happen, oh, and some council negligence, apparently the tital flood gates hadnt been serviced or greased and couldnt be opened/closed, that is hearsay as i wasnt living here when that happened.

I would do what Mick says and you could always use Bondek to pour your suspended concrete floor on.

Slab floor on a dwarf wall construction with internal dwarf wall to take the load of internal load bearing walls, using the bondek system, negates the need for a hefty slab?

That’s the way I would be building it from scratch, even at 700mm above ground level.

What's your take on this?
