Fake rock (lightweight, quick, simple)

- This is my first attempt at making lightweight fake rocks. I wanted something quick and simple. I later used elements of this method to do my first ever fake rock project, a fake rock pond, a quick video of which can be seen here.............

You just saved me hundreds of dollars! Real rocks are a bloody fortune!!!
Check out Stonemakers.
Nice one.............saved myself a fortune on skips as well, as all the old concrete and bricks etc would have had to have gone to skips / local dump
So how heavy was the finished product? I'd like to make a geocache hide like this, heavy enough to firmly stay put but light enough to flip over and find the cache.
Hi, I was wonder about the mesure of the rock?
And how much sand and cement did u need to do it.
I have above ground pipes and currently I have a poorly made wooden box covering them..would be nice to make one of these to cover the pipes for a more natural look. excited to try. Thanks for the videl
Hi Calina. Can't see a problem with what you want to do as long as you can still access them. I've done it with manhole covers. Good luck.
Awesome!!! Great job!.. Now to convince my husband to make some for the yard. :)

That was clever of you to do that for art's sake in your garden! I think they sell different coloured dyes for mixing with mortars and cement, don't they? So a rock can come in several (waterproof) colour shades. :)
Nice work!
I LOVE THIS.......GONNA TRY IT THIS WEEK END....:)
Have fun Susan
Amazing work!
Ta muchly..............
I like this technique. No messing with chicken wire.
Thanks all for the comments
What is the waterproofer?
Very clever. Also, mad skills. It looks amazing.
How durable is it? Could you stand on it?
I've stood on both the polystyrene backed one's and the old concrete rendered one's without any problem. Wouldn't recommend doing it too often though
cool!, very usefull, thanks for showing
good video I plan to follow what you did. question: we live in cold weather [ snow in winter ] and wanted to know if the rock will hold up to the cold. appreciate it if you can advise me. thanksron
+Diane Lewis add some waterproofer to the mix to keep rain / moisture soaking in. When its cold / freezing, theres much less chance of expansion and the render cracking
Awesome, thanks for sharing.
What was the final weight?
when you add the colorant and the water proofer you didn't say what ratio. Is the waterproofer that cylinder of adhesive, and do you add a lot to make the rock waterproof?
I just follow the manufacturers recommendations on the bottle / packet for each product. Being in construction ,we buy our waterproofer in larger quantities, so i just use that. Usually its no more than a capfull per bucket.
great! roughly what is total area of this pond (square meter) and how much actual material (mortar)it took to finish this project
+master strokes Pond is about 1.5m long and maybe 800mm wide. As a builder, i often have old bags of cement left over and i simply use those, so a bit difficult to quantify how much i've used. I would say that a wheel barrow of mortar goes a long way.
will the color of the fake rock fade over time ?
Questions....how do you cure it and do you remove the packing once it's hardened?
Hi Lisa , It sets like any mortar mix so generally the next day its ok to handle
very useful video!!!
Can I make plant pots with this cement/sand/waterproofer mixture? I am looking for a clay like cement mix for making my own plant pots..:) Thank You.
But you need holes at the bottom of the pots for water to escape. Too wet of the soil would cause the plant roots to rot. Cement/sand products are almost waterproof. Too make them completely water proof, you just need to paint them with cement paint (A liquid mixture of cement and water). I wouldn't make a pot out of cement/sand because it would be too heavy. If you make the walls too thin, and without wire frames, they break easily.
Amazing! Thanks!
Thanks Barbara
real nice
Is it possible to use a tripod for the camera work - or that special program that centers the scene.?
Richard Zito Hi Richard. Tbh it was a quick vid for some of my mates to see who then suggested i put it on You Tube as well, even though it was never meant for that and hence the very amateur camera work.
Hi thanks .. well get better at it then - you're
worth watching with your good ideas and all.
there are so many other vid's that'r just silly
Richard Zito Very kind of you to comment , Richard. Thanks.
What a FANTASTIC job. Do you think someone could do this if they never worked with concrete before?
Janice Woods God aye........lol. Its like being back at playschool , messing about with soft clay and so what if it gets messed up, go over it and try again. Let your mind go blank and enjoy.p.s its not concrete, its ordinary 3:1 sand / cement mix ...........
p.s (again) this effort spawned my first fake rock project which may be of use to you as well............ ruclips.net/video/AX2LckCk_Dk/видео.html About to start a slighlty bigger pond / fake rock project shortly myself, got another load of rubble to use up so may as well put it to use and recycle it
Thank you, I am going to give it a try.
Did you paint it once it is dry?
Hi Coy, no it wasn't painted, just left to weather naturally which it does like real rock eg moss etc
What type of concrete mix did you use? Hydraulic?
basic 3:1 mortar mix
Did you finish the bottom??
danessaartist no, i didnt think there was any need as it just sits on the soil and is hidden anyway
how much cement and how much sand.dont understand 3:1 sand / cement
Estela Vargas 3 measures of sand to one measure of cement for example,
3 shovels of sand to one shovel of cement
Has anyone tried this so they can tell me how much it weighs?? I want to make rock that are pretty close to the size of basketballs tho.
+SashaWasHereToday Its surprisingly quite light, probs about a quarter of a same size genuine rock
What type of cement was used exactly?
Ordinary portland cement. In fact , its usually the odd half a bag left over from other jobs and no longer any good for bricklaying, that would otherwise be skipped
How much does it weigh? "Lightweight" isn't exactly the best description.
It is hollow inside so, probably 20-30 pounds.
Its not heavy at all tbh Mika, probably 10lbs
I didn't see enough of the plastic bag texture work. No, just kidding, I saw plenty. But I'm wondering what the finished product weighs. A real rock that size would maybe weigh 150 lbs? I just bought a plastic rock that size for $27 and it weighs maybe 5 lbs. Anyway, that's a good-looking rock, I might try it.
It looks small, but if it was a real boulder, it would weight somewhere near to a hundred pounds. I could not pick up boulders that are one and half of that size from the ground. I can only pick them up if they were on a truck. Trust me, they would break anyone's back.
150 lbs boulder would be a little bigger than that.
