I bought a Bosch laser leveller and I’m so glad I did. It’s been so bloody handy!
I got the laser out and got a level from Padstone One across to the existing building and marked up where Padstone Two has to be height wise.
Then I broke out the Bosch SDS drill and used my new Armeg mortar chisel to carefully remove a few bricks and dry fitted the padstone. It went in perfectly.
Knocked up some strong mortar with sharp sand (for extra resilience) and bedded Padstone Two in place. Checked the level and it’s spot on, not a bad 45 minutes work.
Time for Tea & Medals.
