Caisson for well do it yourself

It often happens that when setting up a well, I want to equip it with additional equipment, but in order to have such an opportunity, you will have to purchase a very expensive industrial one, or make a caisson for the well with your own hands, the dimensions of which will allow you to place everything planned in it. Another reason is possible - the desire to do everything yourself. In this case, it is not necessary to make a large caisson.

Caisson is designed not only for convenient location of various devices in it, but also for protection against freezing of the water supply system.

To this end, it is placed in layers of soil that do not freeze through, and tightly closed with a lid, in order to avoid ingress of cold air inside.

Preparatory work

First, you need to dig a hole under the caisson, the shape and dimensions of which depend on its size. In the factory, the caisson is made of plastic, or metal, and, as a rule, its dimensions are small. Different material can be used for the caisson:

1. Concrete rings.
2. Concrete.
3. Brick.
4. Metal.
5. Polymer sand base.

Let us dwell on them in more detail.

Depending on what the caisson is, you need to dig a hole under it, on the basis that only the hatch should look out above the ground, and leave the body under the ground.

Caisson from concrete rings

The bottom is laid concrete level, and after he thoroughly grasped, you need to wash the bottom of the fallen clay. Then draw a contour to install the ring, and on this markup, apply cement mortar, in order to put the ring in it. On top of the first ring, the solution is again applied and the second is put.

If clay falls on the applied solution during the installation of the next ring, then it must be removed. To do this, you can fix the concrete product, putting a board under it. After removing the clay, the solution is leveled, and the upper ring is lowered.

After installing the rings, thoroughly seal the seams, and make a well out of bricks, such that the hatch is 15 cm above ground level.

Concrete caisson

There is nothing in his technology of making new and unfamiliar. Standard set:

1. Dig a hole.
2. Make a formwork.
3. Install the reinforcement grating.
4. Pour concrete.
5. Make a brick head.

Everything is done on the same principle as the cesspool. The difference is that you need to make sure in advance that there is a hole left for the supply of pipes and electrical cable, and the top plate must be below ground level. From above the warmed hatch is installed, and the concrete caisson is at your service.

Brick caisson

For the manufacture of such a caisson, a used brick is most often used, but this is at the discretion of the owner. As for the pit, there are 2 options for its size:

1. Clearly in form, given the fact that the brick will be adjacent to the wall.
2. More caisson size. In this case, smooth walls are laid, and after the mortar has dried, the voids are filled with soil.

The first option is less laborious, since you have to work less with a shovel, but there are unfilled voids between the wall and the masonry into which rainwater falls.

For a small caisson, you can not make a concrete cover. It is enough to narrow the hole upwards, shifting the brick towards the center when laying.

The resulting neck must be closed insulated hatch.

Polymer sand base

More simple, and less expensive option is the use of precast caisson, made on polymer-sand basis. This material:

1. Resistant to environmental influences.
2. Does not enter into a chemical reaction.
3. Durable.
4. Inexpensive.
5. Differs in ease of installation.
6. Large diameter rings.

No technique is needed for mounting the rings, and their design makes it possible to assemble a caisson of the correct shape, moreover, completely sealed. In addition, it does not need additional waterproofing, and the bottom and hatch are included.

Metal caisson

If you know firsthand the welding work, you can make a metal caisson. It should be designed with stiffeners so that the primer does not press it inwards.

To install this design will require a crane, but, first, it must be protected from moisture, processed both outside and inside.

Cheap such a caisson will not be, given the cost of metal, electrodes, primer with painting, and work equipment. In addition, this product will need to be periodically painted from the inside. For this reason, metal caissons are unpopular.

We will not say what is best for you, since every craftsman decides for himself how he should do better, and this review will only help to make the right decision.
