hi all new here

ive been asked to do a little job for someone regarding new slabs to an existing front step porch the porch its self is very solid consisting of the old council style 600x600 concrete slabs

i would take these up but on the porch there is a suporting metal pole for the roof which is concreted in with the concrete flush with the slabs so it looks like one of them now im planning on going over the top of these with a sharp sand dry mix or would i be better with a morter bed the new slabs are 450x450

any advise would be of great advice

If you do go on top you will need to use a wet mix. Also make sure that you dont breach the damp course and make sure you run the water away from the door

sharp sand,if you knock it up wet with sbr in the mix you can get down to around 10mm bedding

Personally i always use building sand on steps as i fell it has a better grip especially if there is any kind or overhang.

Not so much of an issue if you use sbr in the mix.

Another option...

If the council style slabs are very level with the correct falls and you got very well calibrated new slabs, you may be able to use an external tile adhesive. Also have you considered using a nice anti-slip external floor tile for the step? (They are not much more than Â£20 per m^2)

Or consider Resin Bonded Gravel if it would look right
