This is my first post here so please excuse me if any mistakes.
I am planning to make a carport for my second car. It is not going to be any roof so no approval required from council (confirmed).
The area is 4x4 so 16m2 in total. It is going to be used regularly I want to make it 3 inches thick with iron re enforced.
Now I have never did any thing like this but want to do it my self due to what the local guys asking for it.
What my understanding is:
1. Dig the area with atleast 10 cm depth
2. Use good weed killer and weed mat.
3. Use the base material (which I don't know what to use)
4. Compact it with plate compactor(available from bunnings for hire)
5. Use some liner for waterproofing.
6. Use iron mesh for re enforcing.
7. May be get premix concrete.
I got all the above from reading but as I am new to this, a bit nervous on starting.
Can some one please help me with suggestions or any videos that I can refer.
Sounds like a great project @krishna. Good on you for taking it on. I'm sure our helpful Workshop community members will be happy to help as much as they can.
Welcome to the community and please let me know if you ever need a hand getting the most from the site.
Firstly, your pad needs to be a minimum 100mm as it will have heavy load on it and should be 32MPa. For 16sqm @ 100mm thick you'll need at least 1.6cbm so you're definitely best of getting this delivered as it's a lot to mix in a small mixer.
To be honest, for the amount of work involved in prep, sourcing rebar and having the cement delivered only to have to spread/level/trowel it yourself, you may find you're better off paying someone this time round.
A professional comes with all the gear. Expect to pay $50sqm for standard concrete ($800) to pay someone. They may charge for a minium 20sqm so you'd be looking at $1000.
For you to do it alone you need to account for your time and the effort, any tools/equip you'll need to buy to prep the area and lay/level/trowel the cement (trowel $20, large screed $50, shovel $20, airator $200, timber and star picket to frame the area $100, etc), the materials like rebar and cement (I get cement very cheap @ $150cbm and you'd need to buy 2cbm at $300).
Add to this you getting a professional finish and have someone to fall back on should there be any cracks, etc.
I certainly don't mean to rain on your parade but just want you to go into this with all the info. Sometimes it's better to just pay someone.
Hey @krishna what were you quoted?
You can certainly DIY and save
Also thicken the edges and use SL62 mesh, premix Concrete n25,20,80 mix approx $220m3
There are also plenty of how too videos on youtube along with some hilarious rip-off ones
Pay attention to set and finishing (trowelling) times
Start early morning break in between
Hi @krishna big welcome to the community.
I have to agree with @ProjectPete on this one.
There is so much prep work and initial outlay just for a small job like this one.
Perhaps you could get a few quotes and ask the concretor if he or she doesn't mind if you watch. At least you could get a better idea for your next concreting project.
Kind regards Rob 👍
I'd get another quote. $2k is very unreasonable and you'll find a normal quote will be closer to the $1k mark. Although some businesses charge a minimum square metreage which is what will drive the price up.
You're not based in Perth, are you @krishna ?
