Filling an external hole

[ann_indoors]

I need to fill a hole where my drain pipe used to go (I have new drainpipes) I tried to fill with filler but it all fell into the hole. Can anyone help? )

when you say 'fill a hole where the drain pipe used to go' do you mean the hole in the ground where the down pipe went or are you refering to the drain from you sink, ie through the wall?

If it's through the wall, use mortar the same as the existing. If it's lime mortar use that, if it's cement use that. Mix it so it's as dry as you can work, that way it wont shrink in the hole.

If it's in the groundfill the hole with some rubble first and then concrete over the top about 3 to 6 inches thick.

if its thro a wall put in a half brick or rubble and cement over the top

You could use a tin of expanding foam. It certainly wont fall out.
