Hello everyone,
we are planning to build a light well for our basement window. The light well itself will be constructed in 3 rows, each spaced 30cm (12 inches) apart, with each row having a height of 35cm (14 inches). What I am not quite sure about, and what is sometimes unclear online, is how to properly set the first row of blocks on the ground. Our landscaper said that, given this height, it is sufficient to compact the ground, then apply a 2-5cm (0.8-2 inches) thick layer of hydraulic lime mortar (Trass cement mortar) and lay the first row of blocks on top.
Online, however, it is usually stated that an 80cm (31 inches) deep foundation should be built.
What is the correct approach?
Regards,
Speer

Excavate, compact recycled material layer by layer, pour the foundation into the formwork, lay bricks on mortar. Backfill with recycled material, compact layer by layer, and lay another row of bricks. Behind the last row, install a dimpled membrane and drainage.
How deep this needs to be depends on your frost conditions. For a poorly insulated and heated basement, it might be like this or frost-free.
You can do a lot, and it will certainly hold.
