Gap between concrete steps

[misterhelpful]

well as everybody else has pointed out you need at least sky hooks

Heh, heh. Remind us which aisle we can find them in again!

between the long weights and left handed screwdrivers across from glass hammers

Oh aye! I was looking by the elastic tape measures and welding spots, in the aisle just past the tartan paint.

I'll remember from now on!

Back to serious: Don't just pour cement through until it stops - could breach the dpc and bring damp into the house.

How about a rubber strip - glued both sides and pushed just far enough? Or wood.

Or if cement is really wanted, some variation on the plasterboard hole trick? Some thin plastic folded (Milk bottles) into a V-shape, covered in glue with strings tied to it. Pushed through the gap and pulled back with the strings to stick to the backside. Do in 2 or 3 bits to make slightly less fiddly. Once glue dried, mortar'll work.

Or, as suggested, a GRP stair grip/nosing which can be stuck over the surface of the treads and raise the level enough to hide the gap. Ugly, though - and not cheap.
