How to make a thermos cellar with your own hands

cellar-thermosOn some land plots, the ground water is too close to the surface, so it is not possible to make an underground or dig a traditional cellar. Building an above-ground vegetable storage facility is a rather expensive “pleasure”. But the harvest will not be lost? If you have a similar problem, you can arrange a cellar-thermos, and make one part of it half-buried, and the second to lift off the ground.

Building a thermos cellar

We start the construction of the cellar by digging a pit 55 cm deep, 3.5 m wide and 3 m long. After that, it is necessary to tamp the bottom of the pit with clay. Then on the perimeter of the fill strip Foundation with a width of four bricks. Next, along the edges of the Foundation, we build two walls with a thickness of one brick and a height (at the entrance to the cellar) of 180 cm, and on the opposite side – 160 cm.

For ventilation, three asbestos pipes with a length of 120 cm and a diameter of 80 mm are laid in the walls (two pipes are laid in the front wall, and one in front of them)

Install two doors (internal – double-leaf). The gap between the walls is filled with sawdust and shavings, tamping them tightly.

Now you can start the internal arrangement of the cellar. At the corners, we put racks made of timber (or metal). Shelves and racks are attached to the racks. The crate for the slate coating is also made of bars. On the crate as a heater, pour a layer of sawdust, 0.5 m thick. From above, the cellar-thermos is covered with a reinforced concrete slab, 20 cm thick and again with a slate stele. You can make a concrete slab yourself. To facilitate its weight in the solution, in addition to gravel, we add the same sawdust.

The height of the cellar inside should be 170 cm, which is quite enough to stand in it without bending (a person of average height).

On the upper shelves you can store fruit and jars with homemade preparations, and on the lower – boxes with potatoes, carrots, beets, etc. Lower shelves are still better to do at a height of 40 cm from the floor to avoid flooding potatoes in the spring, if your waterproofing fails. If the spring is “friendly”, then the top of the rapidly melting snow will find a way to bypass any waterproofing.

This semi-underground cellar-thermos is relevant for areas with a high level of groundwater occurrence.
