How to lay sticks for concrete

mengele

Want to concrete a small driveway to a garage I have built. I have 6 x 3 timbers which I can use on the borders. What's the best way to make sure these don't fall over when concrete is going in? As in how should I attach them to the ground? Floor underneath is old road planingscwhich I got a few loads of a few years ago so is very firm and hard to hit anything into?

It's usually steel bar cut into short lengths hammered into ground upright against outside of timber.

The Continental Op

Often done with 10mm rebar cut into lengths and hammered in behind the timber with bent nail used to hold the timber up to the rebar.


^^^^^^ One minute too late.

You need to decide the thickness/depth of the concrete slab, first. That determines the thickness of the side shutters/side timbers. Is there anything to the side of the proposed slab that you can strut from. Alternatively you could use steel pins/steel reinforcing offcuts to hold the timbers in place.
Im sure there are a lot of other ways to do it.

Thinking something like iron/steel rods would need to be inserted on the outside to stop it falling over if you cant hammer in wooden batons.
Drive way is wider than a car so a plank across the top with battons underneath might be a no go.

Cut steaks out of scrap 2x1 or 3x2, drive them in with a sledge and screw the forms into them. Trim off the excess, so you can tamp down the concrete with a long board

Electricians use an attachment to kango drills to drive earth rods into the ground. You could talk to a local plant hire firm and see if it will fit rebar and if you could hire one
