Maria16Has anyone ever installed a granite slab of about 1x2 meters (3.3x6.6 feet) themselves as an entrance doorstep? Are there any experiences or important considerations to keep in mind?
Background: despite several inquiries with our landscapers, we have not yet received an answer about whether they can handle the installation (the first offer was slabs measuring 40x60 cm (16x24 inches) with joints, which I don’t really like). Since we have a reliable company available, we could organize the large slab ourselves. Otherwise, I would have to decide whether I can live with joints or alternatively look for a stonemason...

We had tiles of a similar size installed as flooring in the living room. Tiles of this size are laid using the thick-bed method, meaning directly into fresh concrete or screed. So, proper preparation is important. I would recommend lifting the tile with a crane or excavator, which can also align and press it into place evenly.

1. Prepare the subbase / compact gravel.
2. Construct a U-shaped formwork from wood. The open end should face the entrance door. The three outer sides will later serve as the base for the riser steps, so the formwork should be built very precisely.
3. Fill the formwork with concrete / ready-mix screed. Top edge = top edge of finished floor – slab thickness – 25–35 mm (for bedding granite slab).
4. Once the concrete has cured, remove the formwork. The interior of the U could be filled with gravel and carefully compacted.
5. Apply waterproofing to the door area if necessary. Clean and moisten the cured concrete.
6. Fill the interior of the U with concrete as needed. The concrete on the “U” should have the required thickness plus about 5 mm, possibly with a slight slope.
7. Place the slab and press it into position. Remove excess concrete.
8. Later, bond the riser steps to the outside of the “U.”
That’s how I would do it as a DIY project.

If you’re already unhappy with the joints, I feel sorry for your husband because of the unevenness.

1. I am not married.
2. No one needs to feel sorry for you.
3. He isn’t interested in the look of the joints either.
4. There are landscaping professionals involved who unfortunately have not provided any updates so far (despite repeated requests).
5. It is stated in the original question that, if in doubt, I would look for a stonemason.
It would be nice if you could address the original question or otherwise hold back.
