Thank you
Ps - sorry should have said - house is Victorian with suspended wooden
floors, and there is an underfloor vent in the layers of engineering bricks.
By mortar do you mean cement?
My manhole chambers are made with eng.bricks and ordinary cement, the grey
stuff or OPC.
Better to mix your own mortar I would say.
4:1 sand/cement plus a splodge of plasticiser eg., Feb-mix, or washing up
liquid if it's only a small amount of mortar you are mixing.

1:1:6 would be fine

sand and cement is fine, about 4:1, unless it's below the dpc, in which case
you're better making it 3:1, and a minimum of 12mm deep

So use good strong 2:1 mortar here!
If you want to match rubbish lime mortar color wise, use white cement.
2:1 with waterproofing additive below DPC. Let's not sod about here.;-)
