Raise the house the jack correctly

When overhauling residential buildings, the question often arises of how to lift jacks at home without disturbing the integrity of the building.

How to raise a wooden house to replace the decayed foundation is well known to professional carpenters.

In its essence, this is a standard operation that is performed in order to extend the life of the house for another 50 to 70 years.

Repair and restoration specialists know that it is necessary to raise very large structures.

The lifting operation can be performed in many ways. Most often, jacks with heavy lifting capacity are used for these purposes.

Why does the house rise?

Any mechanism or device that is created by human hands, eventually wears out and requires repair.

This rule applies fully to houses built from a variety of materials. Most often, the foundation of the house is weakened and unfit for use.

At a certain point in time, it becomes clear that the foundation does not perform the functions that are required. And then you have to lift the house on the jacks to fix the situation.

It follows from the foregoing that the building rises for the following purposes:

  • reinforcement of the foundation;
  • repair;
  • replacement of the lower rims.

In the practice of urban development, there is another reason for raising a house - it is moved to another location.

Preparatory stage

Immediately I must say that it's about how to raise a log, beam or panel house. Professionals do not recommend themselves to raise a brick or frame house.

Special technologies and equipment are required here. Before you start lifting the building, you need to properly prepare.

The first step is to make the necessary calculations. The meaning of the calculations is to determine the magnitude of the load at the angle of the structure. For this, the total weight of the house is calculated and divided by 4.

This value requires the selection of a tie or a board of a certain section that will be used as a temporary support.

In everyday practice people use jacks of different types and purposes. With their help, you can lift and vehicles, and wooden buildings.

According to its design, the jacks are divided into the following types:

  • screw;
  • hydraulic;
  • it is fast;
  • rack and pinion;
  • rhombic.

To raise the wooden structure, you need to use a screw jack. All other species are not suitable for these purposes. One jack will suffice for work. If there are two of them, the process of lifting will accelerate.

It is not recommended to lift the building simultaneously with the use of four devices. In this case, the risk of skewing the building increases.

The next step is to determine the location for the installation of the jack and prepare all the necessary materials for work and devices.

Two metal plates will be needed to be put under the jacks. Instead of them it is possible to use cuttings of a board in the thickness of 5 sm and more. From the side of the facade two racks are attached to the corners of the house.

They need to be marked on, which will have to navigate in the process of recovery. Most accurate marks are made with the help of a level.

If this device is not available, the markup can be performed using a plumb and ordinary building level. Reiki must be securely fixed. Labels are applied to both the rail and the corner of the building.

When the wall is raised, the gap between these marks will be equal to the lift height. It is very important to properly install the jack.

It should be located under the lowest log and prop it up. The photo shows a jack mounted under the bottom log of a wooden house.

A jack under the house

Install it on a pre-compacted soil. But it can be difficult. Therefore, under the base of the jack, either a board or a steel plate is placed.

A steel plate measuring 15x15 cm should be placed under the jack head. The plate is needed so that the log does not slip off the head.

Raising the house

Raising the house to the required height is more convenient with two jacks. Each of them is installed under the corner of the house along one wall. When the installation is complete, you can perform a trial upgrade.

At first, one angle rises by 3-4 cm. After this action, a complete inspection of the entire structure is carried out.

If no changes in the structure of the building are detected, then the same height of the second angle is lifted. And again we need to inspect the house from all sides.

In this way, the wall rises to the designated level. The maximum lifting height of one wall must not exceed 10 cm.

When this mark is reached, the supports from the timber are installed under the house, and the jacks are removed.

Now you need to raise the second wall. The sequence of actions of the other side of the house is exactly the same. When lifting, you must strictly control the vertical position of the house.

If at some point the skew of the building has occurred, then stop lifting and move the jack to the lowest place. In this case, it should be installed not vertically, but with a slope.

Do the lifting carefully, a short distance. When the house is leveled, reliable support must be put under it.

Before continuing climbing to a given height, it is necessary to inspect the ground around and find out the causes of the skew.

Lift technology

Many years of practice shows that a wooden house can be raised using a single jack. In this situation, you need to start lifting from the lowest angle.

After this angle has been aligned, the procedure for preparing and lifting the house as a whole must be carried out in the same order in which two jacks are used.

The obvious drawback of this method is that it will take longer and longer to work.

When asked how many jacks should be lifted, the answer is simple - it is more convenient to do this with two jacks. One angle can be raised an average of 5 cm.

Fixing the house in the raised position

Practice shows that it is important not only to properly raise the house to the required height, but also secure it in this position. This can be done in many ways.

To the house was in a stable position, solid corners or a so-called bench are placed under the corners.

In appearance, this device looks like an ordinary bench, only a bench from a bar is collected. It is installed perpendicular to the wall.

The fixing method is chosen depending on the work to be performed on the foundation. The video shows the house in the raised position.

The fineness of the process

The wooden house can be operated without major repairs for several decades.

The weakest link in this structure are the lower rims, which directly contact the ground. Even with high-quality antiseptic treatment, wood is rotted.

Such a house can be repaired and it will remain for another fifty years. That's why you have to lift it with the help of jacks.

In the places where the jacks will be installed, it is necessary to check the quality of the wood. This can be made an ordinary awl. A rotten log pierces without much effort.

You need to prepare for lifting the walls and from the inside. If there is a stove in the house, it is necessary to loosen the joint of the pipe with the roof and do it correctly.

With a careful performance of the repair, you do not have to shift the stove. But the repair of the roof will have to be done. It is necessary to pay attention to the construction of jacks.

It is best that this device has a wide base. In order to raise the house with the help of jacks, it is necessary to follow clearly the available instructions and recommendations.

And then the work will end in a strictly defined time.
