Large Concrete Faux Rock Stepping Stones

How to Make Super-Large Concrete Stepping Stones for a Walkway

Hi Judy:

 

You sound like you’re on the right track as far as the construction method. Since you’re doing such large (HEAVY!) concrete stepping stones, I doubt you will want to place plastic under them – how would you remove it? Unless you trim away the edges of any exposed plastic after everything has cured. That could be an option – just leave the plastic where it is. Certainly shouldn’t hurt anything, though yes perhaps some moisture might get trapped.

 

 

(Don’t forget to review all the how-tos on my website about hypertufa. There’s a page for a recipe for super strong faux rocks, including really big ones: Search for my Faux Rock Recipe.)

 

 

However, you can also pour them without the plastic right into the soil – think about it. Sidewalks and driveways are poured like this. Only thing is some aggregate stone is placed as the first layer before the ‘crete is poured. This might be an option for you too – but perhaps use a layer of small pebble-type stones.

Any additional reinforcing agent would be a good idea, even though you’re using an inner layer of wire mesh within each of the stepping stones. Just know using the fibers will require a blow-torch to singe off all the little fibers that will probably stick out from the ‘crete.

 

I’d encourage you to practice making one big slab [stone]; make a record of the exact recipe ratios you used; let it cure for a few weeks to see what happens and by then you ought to have an idea if it’ll make it long-term and how to tackle the entire project.

 

Best of luck with all your projects and do not hesitate to contact me again if the need arises.
