How to make a foundation plate yourself!

The foundation plate not only has to be load-bearing and with this feature it must guarantee high stability of your building. Rather, it must also have been made to measure and warp-free. Especially in prefabricated houses, a sloping floor slab always leads to the refusal of performance of the home construction company, because the entire house would be forgiven. But even with a small garden shed you would have to compensate for the inclined planes by underlying wedges, which is avoided with proper execution of the bottom plate.
You will need chess tools, a vibratory plate, a concrete mixer and at least two shovels, a hand tamper, a concrete puller and at least two additional helpers. The material requirement consists of steel mesh mats as well as concrete gravel and cement or ready-mixed concrete.

Step 1: preparatory work

According to your foundation plan, you are battling all strip foundations, manholes for drainage pipes and other foundations, such as pipes. B. the staircase base. Lay the drain lines with a slope and close these ditches again including their compaction. Lay the foundation earth electrode and create a connection lug at the later meter cabinet.
Now cover the strip foundations, which was described in detail in a special article. Create a layer of coarse-grained gravel between the foundations, which you condense with a hand-held rammer or a vibrating plate.

Step 2: concreting

For foundation slabs of up to approx. 10 m², you can carry out the concrete work by hand with a concrete mixer and concrete gravel and cement in a mixing ratio of 3: 1. For all larger foundations, it is worth ordering prefabricated concrete, the cubic meter of which you previously calculated based on the foundations and base plate.
Fill in the bituminous concrete layer by layer and compact it with a rammer. When the strip foundations are filled and about 7 cm of concrete are spread out on the continuous board, lay the steel grid mats over their entire surface. Now the complete filling and smoothing is done with a wide concrete puller.

Step 3: Ensure quality

Especially at high outside temperatures, foundation plates can lose their water too fast and crack. So water the plate regularly for the first three days.
