Hi,
I just wanted to check that the following mortar mix would be appropriate for a bricking up a hole (900mm x 600mm) in an internal loading bearing wall (using Class B engineering bricks).

3 parts building sand
1 part cement
No lime
+ Bostik Cementone Mortar Plasticiser

Any thoughts much appreciated.

That sounds more than adequate but equally - if not more important - is ensuring that the new brickwork is either bonded to the existing wall, or mechanically fixed with two or three brackets.
 
Thanks.

I've done the first three courses. First bricks I've ever laid, so I realise that they aren't going to win any beauty prizes, but do they look good enough? (whole wall is going to be battened and plasterboarded so aesthetics are not a problem)

Can you see any fundamental problems? I think the mortar mix was OK, but because the drill attachment didn't fit, I mixed it by hand rather than with a paddle mixer as planned.

Any further thoughts would be much appreciated.

What's at the top of the void? If some form of lintel/steel, then why engineering bricks?
 
Woody, I think Stuart was taking the Michael.

Thanks for all the gentle support :D Nobody has pointed out anything catastrophic, which is all I wanted to check.

There is a concrete lintel at the top. Those bricks were just the cheapest at Wickes (56p) so, as it is an internal wall, I thought there was no point getting anything else. I'm also going to be bricking up a similar sized hole in the same wall that currently has a gas flue box in it.

Fair enough, would blocks have been cheaper?
