How to repair concrete step?

[Caffeine]

Hi

I I have a chunk missing from a concrete step. It’s 300mm long, 60mm high and about 50mm deep. Fell out while some timber steps were being built. I’ve put a board under it and drilled some nails in to help hold and support the new patch, however I’m not sure which product to use to fill it?

advice much appreciated.

Morning @Caffeine 

What a pain 😕 fixable tho  

You may need to remove that top step while you repair it tho.

I would use Earl's 1kg Concremate Expanding Cement 

I used it on repairing my patio and patio posts and it really worked nicely.

I also use melamine for the formwork.

Things to note...

Concretemate firms up fast.

less water is better as it is incredibly runny/liquid

Seal the edges if possible. I used cardboard wedged between the uneven edge and the formwork.

Follow the instructions but use less water a little. 

The colour will be different and a lot smoother then what you patio is.

The other easy fix I can think of is is to either tile the steps (slippery) or a faceplate over the step height to cover the hole.

It's great to see you've already received a helpful reply from the knowledgeable @Dave-1, @Caffeine.

Is that the missing piece sitting on the porch? If it is, you could glue it back in position with Liquid Nails Landscape and then use the Earl's 1kg Concremate Expanding Cement to fill any cracks around to patch. You'd need to be careful that you don't apply so much adhesive that the piece sits proud of the front face.

I think it would be best if you filled the section entirely with the Earl's product.

Please let us know if you have any questions.

Much thanks Dave

I was wandering around Bunnings last night trying to work out which product to use.

 screwed a piece of timber underneath as part of the form work and I’ll use a laminated piece as suggested for the front.

I’ll let you know how it goes.

thanks.

@Caffeine 

Id go short with the height so you can pour the mix in easier, then tap the formwork to get rid of bubbles. Id then come back later and do the last bit of height difference.
I didnt spot that bit that @MitchellMc saw lol Id actually be tempted to see if it can be glued back as it will match closer to what you have.

Note that the concretemate is a super fine powder and reduces down when you mix in the water.
