Hello everyone,
this is not directly related to house construction but seems to have a similar structural approach.
I am building a pool in the garden and have two utility shafts here that I want to cover with a concrete slab, including an opening to later climb down with a ladder.
The walls are made from 24cm (9.5 inches) concrete formwork blocks.
Dimensions of shaft 1 (pool equipment)
1.5m x 2m (5 feet x 6.5 feet)
Dimensions of shaft 2 (water tank)
2m x 2m (6.5 feet x 6.5 feet)
For the access opening, I was thinking of making it the size of a manhole cover, so I can later use a suitable cover for it.
Now the question is, what is the best way to create a concrete slab on top? I have already searched online but only found information about how slabs for houses must be built or references to precast elements.
On the slab of the first shaft, a terrace made of wooden decking will be built. On the slab of the second shaft, soil will be placed later to fully plant the surface.
My specific questions are:
- How should the formwork for this be constructed?
- What kind of reinforcement is required? (For example, is a simple steel reinforcement mesh sufficient?)
- What is the minimum thickness for the slab?
I look forward to your help and advice.
Thank you.
