Hi all

I am about to fit a new staircase in the room showing in the photo at
this link -

http://thehawthornes.org/images/mini...floor%20-2.JPG

Firstly I need to sort out the floor. It is a load of double cobble
bricks laid onto what appears to be sand. The cobbles are about 100mm
tall. I also need a DPM.

Can I just pull up all the cobbles, smooth out whatever is under it,
lay some DPM (what sort/spec??), then pour concrete onto it (anyone
got a decent weblink on how to do this)?

Thanks in advance

Simon

have a look at www.pavingexpert.com for some hints on concrete.

Some thouhts
DO remove cobbles.
DO think about some underfloor insulation - 50mm of polysterne is nice
and will absorb small soil movements without cracking teh concrete
DO think about a decent thick concrete latyer 3-4" at least
DP think about some reinforcing mesh if its more than about 3m long in
any direction. Its cheap enough.
DO think about laying UFH pipes in it when you lay.

In general teh technique is to dig down to teh right depth, smooth off
everything wih a later of sand, ;ay DOPM - l;arge blue plastic sheet -
over all that lot. Then if you ae using insulation, lay that on top.
Then if using it, lay reinforcing grid, and if ;layimng UFH poiopes,
cvonect to thgat, and pressurise to 6bar,.
Then spal down ****loads of concrete - probably about 50mm, or screed if
you thmk you can get away with it.

If you tack boards on teh room edges and use a bar dawn across tehm, you
will end up level and smooth.

Then float the concrete sommoth with a float.
