Why and how to raise the house?

Very often the draft of the house is due to the wrong choice of the foundation. Many people want to save money and make it cheap. As a result - after the first winter skewed house. To prevent these problems, before building a building, it is necessary to perform geological studies of the building site. Only properly executed foundation will save the structure from distortions and subsidence.

The building sank - how to raise the house? This is a laborious and difficult work. First, it is determined which extensions will interfere with the work, they will need to be removed to provide access to the walls. To raise the corner of the house you will need three jacks. The two will need to lift the corner, and the third one should be at hand to secure. It should be remembered: after lifting the wall, 3 chocks are installed and wedged under it. To raise the house, take jacks of different carrying capacity and design, lever-vagi and wedges of different thickness, made of hardwood. They are installed under the wall. Between the logs and the foundation clogged wedges. When you lift the wall up, it deviates along with the opposite. This deviation is at a wall height of 3 meters when lifting:

- at 10 cm - about 5 cm;

- by 30 cm - about 15 cm.

How to raise a house? What measures need to be taken to preserve the integrity of the structure?

If you have furnace heating, it is necessary to disassemble the floor around the oven and the attic ceiling, to clear up to 30 cm the space near the pipe to protect it and the furnace from destruction. You need to remove the door and window bindings.

When lifting the house to a small height or increasing its foundation, it is recommended that the raised and fixed walls be clamped on both sides. Such devices can be thick bars, plates or profile rolling from corners and channels. By 2 or 3 compresses are installed on two opposite sides of the house, having retreated from the corners by 70 cm. Attach them to the walls with nails. Then near the top and bottom logs holes of 20 mm are made, fixing bolts are inserted and tightly clamped. Such a construction is raised to the required height, alternately each side. Before picking up the house on the second side, under the first substitute the stalls from the racks or thick logs. The walls are clamped and wedged in relation to the basement.

Do not go too far down or jerk the walls up - this can lead to chipping angles. It must be ensured that during the ascent there is no displacement of the walls relative to the basement.

Before lifting a house with a jack, it is necessary for him to prepare a platform. It can be shields, boards. A large footprint increases the reliability of the installation of the lifting tool. In order not to damage the log, a metal plate is placed on its end by a pencil. Two jacks raise one side of the house by 80 mm. The pads are put, the devices are transferred to the other side, and everything repeats.

Before lifting the house further, the jack stocks drop, the devices are transferred to the first wall. This transfer continues until the desired height is reached.

It is necessary to follow the precise vertical orientation of the jack. At the slightest deviation from the vertical, the lifting stops and the equipment is adjusted.

In no case should you climb under the walls or slip parts of the body when they rise.
