Cheers for looking.

I am building a U shaped wall to sit a small shed on. the wall is single skin 1m high.

The base block is medium density, do ineed to use these all the way up or can i use the aerated blocks (lighter and easier to transport)?

TIA

Regards

Will the blocks be above ground? If so, you could use the aerated type, but they have a tendency to go manky and algae-covered when left exposed to the elements, so you might want to consider rendering them.

I prefer dense CMUs - you know where you are with them brutes!

unless lightweight blocks are rendered or plastered they tend to fail
go for concrete ,same price just harder work

okay guys concrete it is.

78p each so no price diff, just need to get delivered rather than collect
