How to make a formwork for the foundation
Foundation - the foundation of any building, and the base of the foundation - it's the right formwork, which can make yourself. But how to make the casing, so you do not have problems?

First, let's deal with the fact, that suchformwork and why it is needed. Formwork - a design used for the construction of the foundations of the building mixtures, and it is necessary to keep the mixture in itself and does not allow them to drain.
Formwork is removable and non-removable. For the construction of the bases used removable formwork made of different materials: wood, metal, or polystyrene. Since after the pour of the foundation formwork elements are removed, you should think about in advance, what does it do, because the appearance of the foundations of the building is as important as the interior.
Fixed timbering made ofpolystyrene, a material that can rightly be regarded as the future material. This formwork is very easy to erect, has a light weight, reduce the financial and time costs of construction.
How to make the formwork - a guide to action
If you decide to build a house, garage, bath ordifferent structure and thinking about how to make the formwork for the foundation, then you are on the right track, because before starting to do anything, it is worth to think about all the details, so you do not bite your elbows in despair.
To create the required tools and formworkMaterials that can be purchased in a store or find in their own bins. Today, almost any hardware store you can buy metal molds with a perfectly smooth surface, designed specifically for the formwork. They are fixed to the frame using bolts and fasteners. Advantages of such a design are obvious:
- ease of installation
- smooth surface of the basement
- substantial savings on construction materials
- reduction of time for finishing work
But if you buy the metal sheets you do not havepossible, it is quite possible to manage with a wooden board, that's just the process of creating a casing bit more complicated and will require you some skill and dexterity.
In fact, the most ideal material forconstruction of wooden formwork is a pine board: it is durable and cheap. But here the thickness, depending on the type and purpose of the foundation must be different. Thus, for strip foundation board need not less than "sorokovke", because it will have to withstand a large number of concrete.
Important: thin boards will not withstand the pressure of concrete and just scatter in chips.
After you remove the shuttering frame boards can continue to be used in construction, eg for roughing the floor finish.
But to fill decorative tracks in the garden would be enough and thin, narrow boards with a thickness of 0.1-0.3 cm.
So, after all, how to make the casing of the boards?
First we need to mark on the perimeter of the drivewooden blocks (future shuttering supports). The more, the more solid will design. Next you need to fasten the bars of the board. This is done using usual nails, but they need to clog the inside, so that irregularities were as small as possible.
And to provide additional strength can be mounted on the outside of the wooden formwork spacers with a frequency of approximately one meter.
Important: during the formwork assembly check the level of level and plumb its walls, or a house (or you build it) can turn with a roll.
After assembly and thorough evaluation of its formworkobmesti need a broom and well moistened. This is done so that the tree does not take the moisture in the concrete, thus reducing its strength. if possible, you can use a special wax paper, which will also prevent the absorption of moisture in the boards. And now you can start pouring concrete.
Important: remove the formwork structure should be approximately 2-3 weeks after the concrete is poured, and even better to leave the lists in place until the completion of construction works - so you do not damage the outer wall of the basement, you never know what can happen on the court.
As you can see nothing complicated in the creation of formwork not, the main thing here - do not rush and carefully check all levels. Even I have a saying, "haste makes waste."
