I am in the process of planning a low level deck,I am wondering if it is advisable to bolt the bearers to the slab edge or would it be better to put the stumps a small distance away.If bolting bearers to slab edge should some sort of membrane be between timber & concrete ??
I intend to use 90x45 treated pine bearers.will bolting to the slabedge have any longterm effects.

I cannot answer your questions, but i have a few tips for you.
If you bolt the bearers to the slab, it is technically an extension and may require a building permit. Ths is a really grey area. The rule is if the do not exclude the need for a building permit, then you will probably need one. Also it may impact on any nwarranties or insurance if you dont.
Suggest you try www.mitre10.com.au re decking plans, and go to Bunnings. The reason I say go to bunnings is that the have qualified builders as p[art of their staff. TThey will be able to give you the info you need.
Wehere abouts are you? and what are you making your deck with?

90x45 is too small for a bearer. This is generally your smallest joist size and will span 1600mm on a continuous run at 450mm centres. It is also only available with a H3 treatment - above gound use only.
If you are going to bolt bearers to a slab, I would recommend 90x70 treated pine making sure they are the H4 tretaed solid type and not the laminated H3 type.

If bolting to the house, keep in mind that you don't breach the termite barrier or weep holes.
Depending on the height of your slab this can be hard to achieve without doing so.
It would be good practice to at least paint the back of the pole plate
