Hi All,
I am looking to have a 28m block wall built in place of fences (some of which are now neatly stacked up).
I'm trying to understand the block layout, number of pillars and expansion joints that various people have told me I need!
So the wall will be 2m high, 28m long, and stepping downwards. I want to plan out the foundations such that I dont need to mess about with filling in gaps at the base to get the block lines level further up - rather drop the foundation by a block height where the wall height will drop.
Should I look to put a pillar every 3m roughly? (each block is 440mm + 10mm mortar makes it 7 blocks at 3.14m or 6 blocks at 2.69m)
If the wall needs expansion joints, how far should these be, and how to place these in terms of the pillars?
Any diagrams or calculators for pillars/expansions would be useful to help me calculate!
Also from videos I can find, pillars are built using 2 blocks on their side for one row, and 1 block upright for the next. I'm planning on using 140mm blocks so this wouldn't work - can I use 100mm blocks on the flats, and 140 on the uprights? Or am I barking up the wrong tree?
