packing out steps

[brian c]

got another job but the steps need packing out a fair bit about 65mm or so,what do you guys do to pack out?i have my own method but was wondering what you guys do.

Is that on the tread or the riser?

If your talking concrete step, I would sbr slurry then 3-4 to 1 screed

 

[brian c]

its on the riser,i need to get it square to affix a tile to it.

I usually pack out by using old tiles and a sand and cement mix.

How many steps and what size?

Is it 65mm all over or tapered?

 

[David - Tradetiler]

I did it once by drilling and half screwing a fair few decent screws in the face as anchors. Then I made some shuttering to the exact place and back angle and filled with mix of 6mm granite chippings (granno) and neat cement for max strength (high stress point on the nose of a step) you don’t want it breaking off an someone falling down a flight of stairs …..

“Hello is that injurylawyers4U ? I have fallen down some stairs that broke away beneath me!!.........”

all over there is 5 steps and thay range from 1.2m to 1.9m and are 300mm by 65mm to be packed out on each step.I have bolstered the edge off on other jobs before

With that size, the only sensible way is to shutter up and cast with 6:1 concrete made with a 10mm aggregate. Roughen and wash down the surface 1st, then apply a PVA bonding coat. Concrete while the PVA ins tacky.
