Garden Room Build - Week 9: Ep 10: How to create foundation piers for a Garden office

It's week 9 and in this video we build one of the foundation block piers on the compacted MOT Type 1 base. Its landscape fabric, then around 50 to 100 mm of compacted MOT Type 1, then a mortar bed then a block, mortar and a second block.
The should give a very stable base for the garden room, enjoy!
The mortar mix is captured in a separate video.

Great video. I know it seems like a simple task but I’ve never understood how it’s done in practice.

Thanks for the comment! Glad you found it interesting!

I was looking at doing the oakwood threaded bar method but the concrete blocks are a much cheaper. Maybe harder to level but small price to pay.

[@FatManBuilds]

Yes I considered that method too, but decided on the blocks, again for cost, levelling was ok once you get a rhythm going. Two years since the blocks were done and no issues so far!

Nicely done. Looking to do exactly the same, this really helps! Do you have equal spacing between all the blocks both horizontal and vertically?

[@FatManBuilds]

Thanks, mine did work out pretty even, around 1.5 along the long side, and about 1.2 along the short side, I ended with 15 piers in 3 rows of 5 along the long side! Good luck with yours!

Did you use about one bag of MOT per block? Thx

[@FatManBuilds]

Yes probably on average, there were a couple where the ground was softer so I kept digging till it firmed up and I was definitely through the top soil. one had about three in!
