It is not so difficult to build formwork with your own hands , however, this process should be treated 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. Placing boards is necessary in terms of 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.
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 cooked boards or boards, and then without fail we check their verticality by the level;
- from the outside of the structure we install struts 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, and also eliminates the need for additional insulation of the building.
So, most often, fixed formwork with your 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. The 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 it is necessary to make a practical marking of walls, slopes of windows and doors, openings for communications in accordance with the project. In order for the walls to be strong, it is imperative to do dressing of the seams.
After 3-4 layers of blocks have already been exposed, you can start pouring concrete while tamping it. The last row of elements should only be filled in half, with the mortar seam inside the formwork. Reinforcement and concrete must be of very high quality. Only in this case the building will 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.
