The number of dwarfs depends on various, e.g. the size and shape of the sun deck, the size of the beams used and the location of the sundeck (up against the house wall or not). The rule of thumb is 1 dwarf per 2m², based on 160 cm between dwarves, but this can vary as previously stated.
For example, a 64m² square platform (8m x 8m), not adjacent to a house wall, could have ranges from 120cm to 200cm between dwarfs. Each dwarf can cover from 1m² up to 2.5m². But it depends on the size of the beams and how much the platform may "bounce".
If, on the other hand, the sun deck is up against the house wall, one row of dwarfs is saved and a beam along the wall is put in instead. And the bigger the platform, the fewer dwarfs you need per square meter, and the shape of the platform affects the number of pillars needed for it.
The distance between the Dwarfs under the sun deck is from 120 cm to 200 cm, depending on the size of the beams used as well as the shape and size of the platform, but the larger the platform, the fewer Dwarfs you need per square meter. Each dwarf can cover from 1m² up to 2.5m². It also depends on how much the platform may "bounce".
Some people choose to cast concrete around wooden poles into tubes on site, but if they are to last well, they need the right knowledge, ability and a plenty of time.
It is important to keep in mind that when timber is attached directly to the concrete, the timber will wither over time. This is because the wood absorbs moisture from the concrete and the soil under the concrete cylinder and if no air gets to this part of the wood, it does not manage to dry in between. Therefore, the timber is much more likely to rot earlier when this method is used.
When the timber, on the other hand, is attached to a connector (beam or pole shoe) on top of the Dwarf, air circles around it and it dries in between, which extends the life of the timber significantly.
The Dwarfs are made of C45 (MPa) concrete and a powerful 8mm iron rebar is in the pillar, which makes the pillar many times stronger than ready made pillar concrete.
The shape of the dwarfs also ensures maximum stability in the soil that is achieved by utilizing the weight of the soil closest to them.
In addition, the dwarfs save a lot of time and ease work in narrow backyards. The connectors also make the job both easier and more precise, as it is easy to adjust the height and direction of each beam after it has been fastened down.
The shape of the dwarfs ensures maximum stability in the soil that is achieved by utilizing the weight of the soil closest to them. Thus, they carry soil around them, which is often many times their own weight.
The general rule is that the fill for pillars in the ground must be compressible and frost-free. A good filling must achieve at least the bottom width of the dwarf down below it and next to it. A wooden pole can be used to compact along the pillar once it has been filled up.
Load capacity and tensile strength are reduced by up to 50% when a good filling is poorly compacted. Good compaction is therefore the most important factor in the carrying capacity and tensile strength of the dwarfs. The dwarfs can, however, be completely buried in uncompressed landfill or even earthy soil. Their load-bearing capacity and tensile strength are much higher than in traditional columns. Then it can be assumed that they can up to 4-5 times their own weight in the earth.

The shape of the dwarfs ensures maximum stability in the soil that is achieved by utilizing the weight of the soil closest to them.
A tube cast on site can weigh 50 kg and requires no more effort than its own weight (50 kg) to release it from the ground. In comparison, the Dwarf Purkur weighs 50 kg, but in order to release it from the soil, a minimum of 300 kg effort is required.
The shape of the Dwarves means that they are very stuck in the soil and do not crawl out of the ground during frost changes, as is the case with the cylinders.
