Making cement pavers

[JB]

Making a few pavers (about 10, as stepping stones) using a plastic tub about 30cm x 20cm as a mould. First one failed using 1:4 cement/aggregate mix, but that was probably because I couldn't resist testing it before it was completely dry. It was about 5cm thick. If anyone has made their own pavers, any advice on mix ratios, reinforcing required (?) or any other tips would be much appreciated. Thanks.

Leave the thing alone for a week before touching it. Keep damp.

[JB]

Thanks mate.

aggregate mix

What did that consist of?

Maybe make some washed aggregate steptoes?

[JB]

Aggregate was sand and small stones. What's washed aggregate?

[autogenous]

See topic polished concrete :)

Better off without reo in pieces of those dimensions, to avoid possible corrosion and cracking therefrom. Use packed bedding sand for firm support, also to avoid cracking. Use as little mix water as possible - only enough to wet the cement particles, but keep damp topside while curing as said.

Hi JB.
Have made a lot of pavers for walkways. Used 65 x 50 angle iron to make up frames so the pavers are 65 thick. I use GP cement and pre-mix which works out at 1:2:3 (coment, sand aggregate). As Joe says, make the mix as dry as possible while still workable to get right in the corners. I lift the frames off after 24 hours and leave pavers to cure for at least a week keeping damp under a tarp. Then stack them until used. Have had no problems with cracking or breaking once I got the amount of water right. In order to get the frames off easily I made the frames 10 mm oversize and line them with plastic garden edging very lightly oiled with el-cheapo engine oil and they are a doddle to lift straight off.

david, auto, joe, feral, thanks. No reo, dry mix, keep damp, leave a week; should be right now.

This is very interesting, would this be a lot cheaper than buying them?. I guess you can also paint them to your required taste.

I've been making them whenever I have half a barrow or so left over. The pre-mix I use is $80 per metre and a bag of cement is what, $6? So, yeah, I reckon it would be heaps cheaper than buying them.

I use these round cardboard lids as the mould - only one paver per mould and then they're no good. I've got heaps of them off drums that my old man gets chlorine tablets in.

Re. painting them. I don't think I'd paint them but there are some options for colouring. There is oxide that you can add to off-white cement. Or you can get the colouring that is used for stenciling - comes in a lot of colours. Mine are concrete colour :)

Yeah that's the terminology i was thinking of not actual paint, paint, sorry i'm still learning the terms. Is it possible for anyone to post a pic, least that way i know how they can look as i'm tipping my 1st ones will look like a sloppy cake .

[joe greiner]

Like silent says, they're a great use for leftover mix, in contrast to wasting it. That brings the cost down close to zero.

If you want to get fancy, cast them face-down on a damp sand bed, with pebbles, seashells, pieces of tile etc., partially embedded in the sand. Brush off the sand after de-molding next day, then keep damp as said. Such work can cost a king's ransom at the artsy-crafty shops.

I'm not sure about cost but the satisfaction of making them to your own design would be a benefit. Also I guess if you had limited access to a backyard it would be beneficial to make them onsite.

I told someone once I was gonna make some and they laughed. I'm happy to see people actually do "roll their own" so to speak.

I love the idea, i was in the process of designing my next landscape project along the side of the house and needed to find a paver. I already have a cement mixer i bought last year for my edging so i guess i can pull it out again and have some fun.

Can you use TP as form work? and what would you need as a base to keep the bottom flat and flush with the form work, when you take away the form work?

[corbs]

Brilliant idea, can't believe I hadn't thought of doing this myself! Sorry for the hijack... but how thick would I need to make pavers for a basketball court (6x4m)? I am thinking around 60mm with a bit of gal mesh to reinforce the paver.

Cheers,
