There is a possibility of placing pedestals directly on the ground, but the ground should be properly prepared. To set the pedestals on the ground, you need to remove approximately 50 cm of soil. Then, fill the area with coarse gravel, preferably with a size of 40-80 mm, followed by finer gravel (0-20 mm), and compact the layers thoroughly with a compactor. However, it's important to note that such ground preparation depends on local geological conditions, and even with correct layering, ground settlement and periodic adjustment of the pedestals may still occur.
For placing pedestals directly on the ground, we recommend using concrete blocks, which provide stable and durable support for the pedestals. An elevated terrace, like any type of structure, requires a solid foundation in the ground. More information about types of substrates and their properties can be found in the article - Terrace sand and gravel - is it a good base?
