Casting a slab for air/water heat pump

[Danne213]

Dug down 40-50cm and filled it with gravel. The "first" slab is 10cm as a Mitsubishi outdoor unit on a stand was planned, but it could not be delivered.

When it became a CTC (haven't received it yet), I poured an additional 10cm over the paving stones.

The center distance of the outdoor unit's legs 610/614 is 1155, I added a couple of cm on each side. The total width is roughly as wide as the outdoor unit.

Cut a slope towards the drain in the middle directly in the form. You get the chamfer with a triangular strip in any size.

If you only need to pour once, 10cm of concrete will suffice.

This is what it looks like at home

Neatly. Do you lead the condensate water into a soakaway pit under the slab?

Neatly. Do you lead the condensate water into a stone pit under the slab?

Thank you.
It continues in the stormwater pipe which then leads into a ditch further away.

Do you have the possibility to provide the dimensions of your plate's surface area (width x length)?

Do you have the possibility to provide the surface dimensions (width x length) of your slab?

I can check when I’m home tonight

Did you have the outer dimensions?

Did you have the outer dimensions?

Oh sorry, I forgot this.

Now I'm in the USA this week so I won't be able to check until the middle of next week. But the dimensions of the outer part are:

Width 1245mm
Depth: 545mm

And the slab is about 20cm wider on each side, then about 20cm wider at the back, and maybe 30cm at the front.
The thickness is about as high as an SJ pallet.
