Supporting Pillars on Concrete Wall

[self builder 123]

Hi

We are building a concrete wall using 440mm x 215mm x 100mm dense standard blocks placed on flat. Hence the wall will be 215mm wide.

The wall will be 26.3m long, tied at both ends to existing walls and will be 2m tall at the maximum height.

I understand that we need to have supporting pillars incorporated into this wall, even though it is 215mm wide.

Can any one tell me how far apart the supporting pillars should be ?

Cheers

I'd recommend building the wall in bays. Say 5 bays of approx 5m each. By doing this you can introduce piers and also construction/expansion joints. Turn the blocks 90 degrees at the end of each bay to create a 215 x 440mm pier. Add one expansion joint and job done.
