It’s not so difficult to build formwork with your own hands , but you should take this process responsibly, since it depends on the mentioned element how strong your building will be. It should be noted that the presented design can be removable and non-removable. The first option is much easier to build. For work, you will need wooden boards, stakes and mastic, which is coated with the inner surface of the structure. In this case, the aerial part of the base will be smooth and beautiful.
Before you build the formwork with your own hands, you must definitely dig a trench of a given width and depth. The part of the soil on which the building in question will be installed must be perfectly flat and strong. It is necessary to exhibit boards according to the level. For work you need a hammer, nails and lumber. However, finished metal forms are now sold in stores, which have a smooth surface and are very easy to mount.
In order to properly build the formwork with your own hands, you should adhere to the following action plan:
- insert wooden blocks into the ground , which will serve as supports;
- to them with the help of nails we nail the prepared boards or boards, after which, without fail, we check their verticality by level;
- from the outside of the structure we install spacers that will give it rigidity;
- we check the correctness of geometric shapes and dimensions of the structure.
So, the formwork is done with your own hands, you can start
pouring concrete. After the base is completely dry, the boards need to be removed.
Now consider the technology of building a fixed structure. Its advantage is that it makes the walls stronger, moreover, eliminates the need for additional insulation of the building.
So, most often, fixed formwork with one's own hands is built from polystyrene foam blocks. Each element has grooves, thanks to which it is attached to the previous one. Naturally, in this case, you will need a lot of reinforcing bars. Blocks should be installed on the finished underground part of the base, covered with a waterproofing film. It is necessary to pre-wrap reinforcement into it, on which formwork will subsequently be worn.
It’s not so difficult to build such a structure as a polystyrene foam formwork. However, pay maximum attention to laying the first layer. The fact is that at this stage, practical marking of walls, slopes of windows and doors, openings for communications in accordance with the project should be made. In order for the walls to be strong, it is imperative to dress the joints.
After 3-4 layers of blocks are already exposed, it is possible to begin pouring concrete with its simultaneous ramming. The last row of elements should be filled only in half, and the seam of the solution should be inside the formwork. Reinforcement and concrete must be of very high quality. Only in this case will the building be strong and stable.
It should be noted that, in addition to wall insulation, the mentioned structure allows the living room to “breathe”. In addition, for the construction of such formwork you will not need special equipment, the rental of which, as a rule, is quite expensive. Thus, you will save money and speed up the process of building a building.
