    Default concrete slab

    I have an area at the back of the house that I am going to concrete, its going to also have a retaining wall(small one) at the back of the slab. I haven't do it before but have the father inlaw coming up for the weekend, and he has done a few before. What I wondered was how thick should I make it? no vehicles. Reo? Also how level does the site need to be? and if I need to fill should I use blue metal? What is the cheapest way to make the boxwork, ie, what type of wood and thickness.

    Thanks for any advice.

    how thick should I make it? 100mm
    Reo? yes
    Also how level does the site need to be? The flatter it is the less concrete you use....
    and if I need to fill should I use blue metal? No - crusher dust or a sandy loam.
    What is the cheapest way to make the boxwork, ie, what type of wood and thickness. whatever you can find at the local Aroundagain or tip shop - ripped down external doors are quite useful.

    at least 4" thick

    F52 reo at least.

    The more level the better (unless you have access to cheap concrete

    and if I need to fill should I use blue metal?
    define 'blue metal' ...

    I wouldn't use sandy loam (sorry SBD), personally I use 20NDCR to fill low areas (ok, I lie, for my own use I just add more concrete

    What is the cheapest way to make the boxwork, ie, what type of wood and thickness.
    Anything reasonable stiff, 4" x .5", hardwood is better than pine, best to have plenty of wood (2" x 1") stakes or metal star stakes, the more the merrier to support the formwork.

    Thanks for any advice.
    that'll be $1.65 plus GST thanks

    Now, this retaining wall, is that going to be built on top of the slab ?
    how small?
    made of what ?

    All important questions, trust me

    Thanks for all the info. The wall will only be about 400mm, two besser blocks. Knocked up the form work today, got to dig out the trench tomorrow. I think I will lose a kilo or two in the process project.
