In the absence of proper capital and in desire, the construction of the foundation can be performed on their own. But, as with any new, unfamiliar business, you need to know some nuances and rules. Before starting the construction of the foundation, it is necessary to determine the composition of the soil where you are going to start building. This can be done in a simple way, dug a hole 1 meter deep and examined the soil structure. But it is better to turn to specialists for this.
To build a strip foundation, it is necessary to remove a layer of fertile soil over the entire area of the future building. The depth to which must be removed within 30 cm, and in a good way to clay. Next, a ditch is digging around the perimeter with a depth of 60 – 70 cm and 50 cm wide.
The following action is the election of formwork. The formwork is made from the board 2.5cm. Shields of the desired sizes are chopped from it and fixed along the edge of the trench. The more reliable you are to fix them, the calmer the concrete fill will pass. Most often, due to non-high-quality strengthening of formwork, the concrete is squeezed out by one of its sides.
After the formwork is built, you need to install the reinforcing frame inside. It is made of reinforcement with a cross section of 10 – 12 mm. If it is possible to rent a knitting gun, then it is better to use it, if there is no such opportunity, you will have to cook with electric welding.
Before pouring, do not forget to insert the trimming of the pipes into the formwork, which will serve in the future for ventilation, otherwise then, you will have to suffer for a long time, abrasion holes. During the fill, do not forget that the less cold seams will be in your foundation, the stronger and more reliable it will be.
