Following the foundations of our container construction: we pour the concrete and make the blocks.
Today we are moving on to the next step: pouring the foundations and making the blocks on which the containers will rest.

The studs: 50 centimeters on each side for single studs and 50 centimeters by 80 centimeters for double studs.
The quantity of concrete to be poured: 4m3, for this quantity it is easier to order a truck-mixer than to do it on site.
We put a few centimeters of concrete at the bottom of the excavation and we place the reinforcement then we finish by filling up to the desired height.
It is a fairly quick operation since the truck stayed barely 1 hour on site. The actual pouring work lasted only 20 minutes.
It must be left to dry for a week before the next step.

The work begins with the realization of a new and even more precise tracing. This operation must be carried out with great rigor. We check the distances and especially the squareness.
It is very important to have a perfect tracing because the containers being products made in an industrial way, they have dimensions precise to the millimeter and they are perfectly square. From now on, we trace the markings on the foundations, which is simpler.
The forms will be held on the foundations by metal rods and adjusted with wooden wedges so that they do not move when the concrete is poured.
The reinforcement intended to reinforce the concrete is taken in the foundations with chemical sealants.
Here is what it looks like before the formwork is put in place, here for a single stud and there for a double stud.
As you will see later, the containers being attached to the existing house, the foundations for the container should be placed as close as possible to the foundations of the house. This is what we are doing here.
The formwork is made to measure and on site.
The plates have arrived. Ideally they should be galvanized to protect them from corrosion. But as we are in a period of confinement this operation could not be done. They are protected by anti-rust paint.
The formworks have been installed. They were planned a little higher than the desired level and markings are made all around with the laser level. These marks will be used to position in height the plates on which the containers will rest.

The concrete is poured and the height of the plates is adjusted with the laser level. This step is very important. It is important to be sure that the levels are right because the slightest significant deviation would put the containers in overhang for example and make the operation complicated or even impractical.
In theory a container needs to rest on these 4 corners. As far as we are concerned, we started on a much larger number of studs because we are going to make openings inside these containers which will weaken them. So to make sure that we keep the integrity of the containers, we have practically doubled the number of studs.
Once finished, we have to wait 3 weeks of drying to proceed to the next step, that is to say the long awaited break of the containers.
While waiting for the drying of the blocks, we finalize the evacuation of rainwater with the construction of a new sump.
Our house already has one but it will not be sufficient to receive the additional water from the roof of the containers, i.e. almost 90 square meters. We will see in another video the installation of the rainwater network and the manholes.
The sump: a large deep hole in which we place a concrete well around which we place large gravel. A pipe will bring the rainwater which will be evacuated naturally into the ground. The whole is covered with a layer of earth. Afterwards you can't see anything.
Note that a sump must be located at least 3 meters from the foundations of your house.
We meet again for the next video where we will see the lower part of the containers, i.e. the stone work and the insulation.
