Hello everyone!

I'm going to build a pool on a sloping rock. Exciting project :)

A retaining wall will be built and the "insides" will be filled and a slab will be cast. I wanted to anchor both the base for the retaining wall and the back edge of the foundation with stainless acid-resistant reinforcement, does anyone know where to find it cheaply? No one seems to have it in stock, and there's a lot of shipping costs involved. I live in southern Sweden.
The forces will come both from the side and directly from above, so I think that 16mm reinforcement should be over-dimensioned.
Length of retaining wall 6m, height approx. 1.2m
Slab size 6x6m
 
There is fully threaded stainless steel at Jula, but hot-dip galvanized threaded rod is also sufficient. Available at larger building supply stores. Not electroplated. Regular rebar works as well. It is doweled into the rock 10cm and a hole is drilled in the leca, which is placed over and cast with slurry (watery concrete). The holes in the stone are 25 - 30 mm and 16 bar is good. It will last as long as you live.

EDIT The bars should reach up to the edge of the stone, so the next layer does not need to be drilled.
