ᐅ Garden wall

Hello,

I have a question.
I need to build a garden wall on one side of my property, which is about 27m long (89 feet). The wall should be built using 17.5cm (7 inch) formwork blocks. Last year, I built one on the other side of the property and proceeded as follows:
- Excavated 80cm (31.5 inches) deep
- Poured a concrete foundation
- Laid 3 rows of formwork blocks and then poured concrete inside them

On the other side, only one row of blocks is needed because the terrain (road) slopes a bit. Now, a friend suggested I do it this way:
- Excavate 80cm (31.5 inches) deep
- Fill with 30cm (12 inches) of crushed stone and compact it (we still have plenty of crushed stone left)
- Then use lean concrete and lay the blocks to the desired height
- Fill the blocks with concrete, done!

The second wall won't have to withstand any load except maybe a fence that will be anchored to it.

What do you think, could this work? It would save a lot of time and I wouldn’t have to dispose of the remaining crushed stone. ;-)

Best regards,
Tobi

Hi,

how did you manage that? I’m currently planning something similar. I still need to do some backfilling, and the wall will have to support that...

Hello Erich ... uhh I mean Tobi 😉

May I ask why you want to build a wall on two sides of your property?
Is that even allowed without any issues (serious question)?

Hi!

I’m new here and have already introduced myself 🙂)...
I’m dealing with the same issue right now, but my excavation is only about 60 cm (24 inches) deep… Do you think that would be enough to build a wall about 1.80 m (5 ft 11 in) high on top?
Would you include some kind of joint along the entire length? (25 m / 82 ft)
The excavation is a bit wider than the width of a shovel—would that be sufficient?
In addition, the concrete will be poured with formwork just over 20 cm (8 inches) above ground level...

Would you recommend some kind of frost protection?

Regards & thanks, have a nice day 🙂)
