Setting out blockwork from foundation

[Lee Edwards]

Hi all. I hope you are well.

I am in the process of building a summer house in my back garden. I have just poured the concrete foundation which didn't go as precise as I had planned. The lads pumping in the concrete were pretty hasty at 6.30pm and kept telling me that being 10mm lower in some places on my level markers is ok and it can be built up in muck.

So I have a couple places either side which have around 1 metre length which is 10mm below the level I wanted. Now I need to think about laying the blockwork (just one course) for the beam and block floor to sit on. Now I need this to be as near perfect as it can be.

The advice I need is, do I set the 1st block at the highest part of the foundation and then add more mortar to get it level


Do I start from the corners 1st?

What mix of sand and cement do I use for this course?

Any advice would be great. Or any Bricklayers in Surrey would be keen to do the job? Thanks

Search for "datum peg" and "setting out profiles".

Start at the corners and work from them towards the middle of each elevation.

3:1 mix ratio.

Make sure your line is not sagging on the sides where the beams will sit

Hi Woody. Thanks so much for the reply and advice. When you say search, do you mean on the forum or actually look it on on the web?

Hopefully you are still sleeping as your reply was nearly midnight.

Cheers
