If you have a vacation home, and you have a need to build a basement under it, you will need to be prepared for physical exertion, discomfort when working in confined spaces and dirt in the house during the work. Before starting work, it is mandatory to figure out what type of soil under the house. For example, if a house is small, and the sand beneath it, he is in the course of digging (or later in time) will begin to crumble, would weaken the ground under the foundation, and this can cause damage. You also need to know the level of ground water passing under the house. If it is high, then dig a cellar pointless Pogrebnaya pit will be permanently filled with water. And even the concrete walls in this case will not help to stay dry cellar. As for the soil and groundwater can ask the neighbors or refer to specialists. Next, decide on a place of digging. The place must be chosen carefully, away from the walls of houses, pillars supporting the beams from the basement furnace, if any. After that, proceed to the digging. If a subfield of a lot of space, excavated soil can be spread evenly here, it’s even a little warm house. Better dig two or three – so it will be easier and safer. From a physical perspective, the ideal form of the cellar – round, in which case the ground pressure on the walls of the cellar is distributed more evenly. No wonder the gas pipes, water pipes made of round section. However, the cellar of cylindrical shape are extremely rare. Now we need to determine the order of which will be carried out of the cellar wall. They can be concrete, brick, wood or metal. The latest version is worse because the metal rusts quickly especially when in contact with the ground, ill keep warm, to work with him in the cellar is very inconvenient, so consider this option would not be. For the construction of the cellar of the boards, you must first make a metal frame. It is made from the profile fits, for example, the metal corner of the parties at least 5 cm It can be either welded or joined with the bolts. Such a framework will provide greater strength cellar, and if necessary will provide support for the upper part of the cellar. If the cellar is from the ceiling, it is recommended to add to the frame of the top one or two metal cross. After building the frame of the boards collect the cellar walls, pre-sawed to the desired length and processed by special trains to protect against rot and rodents. When erecting walls between the wall itself and the land needed to pave any waterproofing material. Now the field is the cellar. Placed on the ground a few lag, the thicker the better. That they do not rot, they can be placed under the roofing material. In the logs are stacked floor boards thickness of 5-7 cm can make a cement floor, but keep in mind that he had a long drying, curing occurs within 20-30 days, depending on the thickness of the layer. After that, from thick boards are gaining the ceiling of the cellar, leaving room for the hatch. The advantage of the wooden cellar is the relative ease of repair, easier to install and fix shelves, cabinets or stairs. Disadvantage – boards exposed to moisture, and over time they will have to change. The cellar of the brick – a troublesome and expensive. Apart from the bricks take more cement, fine sand and cement mixers. First you need to prepare the foundation. For this purpose a hole is dug around the perimeter of a width of 35-40 cm and a depth of 40 cm and filled with cement mortar to the floor. If the foundation is needed above, then after a preliminary freezing basement in the earth above him make the necessary height of the formwork and pour cement mortar. Spread on the foundation walls of brick can be no earlier than seven days after pouring. Brickwork should be as thick as two bricks, if the thickness – or worse. Between the rows every 40-50 cm is recommended to lay the metal reinforcing mesh to prevent the occurrence of cracks in the wall. Floor and ceiling made of wood. In this place of contact between wood and cement elements proizolirovat better, because the cement absorbs moisture and can pass it on wood. Before the construction of the cellar with concrete walls need to do a frame made of rebar. Reinforcement bars should be vertical with a distance between 15-20 cm and 30-40 cm in the horizontal frame is constructed by welding at a distance of about 10 cm from the walls of the pit. Then they make the inner walls of the formwork, exterior walls serve as a primer. When the formwork is ready, you can upload. In the solution, you can add a variety of unwanted metal objects, pieces of bricks and stones (always clean). This will give greater density and design will save the cost of cement.
