As a rule, are subject to destruction logs under the Windows, the lower crowns of log cabins, floor joists, and flooring. Renovation should start only after determining the cause of the disease and its extent. For this release the lower crown and the lower part until, until it gets natural soil. Don't get complacent, if the result of the external examination has found no traces of destruction of wood.
The log needs to be tapped with a hammer that will allow to detect the affected area by the characteristic sound and the places where later will be installed temporary supports, jacks and wedges.
To raise the frame, use any Jack with sufficient capacity, for example, train or car Jack truck. Depending on the construction of the Foundation frame should be raised in two ways. So, if the frame is mounted on intermediate and corner poles, then the Jack will be installed under a log.
If the log stands on a strip Foundation, you should first identify weaknesses in the logs and do there holes like Windows, and then insert the lever, or the piece rails. The inner end of the lever is placed on a secure base. Directly the Jack is mounted under the outer.
The recovery log should be done very carefully, observing the synchronicity. If you are using one of the Jack after you put one part of the house, you need to set the focus. Only after that can continue to rise in a different spot.
Experienced specialists strongly recommend inspection of the structures of log house in the fall and spring, carefully tapping and probing each log. Pay particular attention to the insulation, since this depends largely on the lifespan of wooden houses.
Advice 2: How to raise the Foundation of the house
For any owner of a country home task is to repair the Foundation and raise the building above the ground may seem daunting. Do we have to write a team of professional builders? Or will be able to cope with the job yourself?
For example, you have to raise the frame home or bath to tear down the old Foundation and build a new one in accordance with your ideas. Where should you start? All you need is one assistant.
Corner house back two jacks. Carefully raise the selected corner to a height of approximately two centimeters. For temporary support put strip of appropriate thickness.
Now move on to the next corner and perform the same operation. The procedure is simple if the frame is already detached from the old Foundation. Pay special attention to the time when all the corners of the house is already on the pads, except for one or two old logs. The careless lifting of a corner of the Jack frame can get away with props.
Don't be tempted to speed up the process, increasing the height to which lift the corner of the house. This can lead to dangerous misalignment of the structures and unpredictable consequences. So proceed without haste, limited to lifting each corner just consistently a half to two inches in a single pass.
The specified bias is possible for the reason that described by way of lifting results in the action of total force from the horizontal component of the vector. Developed by the jacking force may lead to podpisaniu of logs and warp of a reference platform. Note also that in alternate (i.e. non-uniform) lifting angles horizontal component can appear due to the shift of the center of gravity of the structure.
In the works to lift the Foundationand will certainly consider the question of insurance and compliance with security measures. As soon as the frame is raised a few inches, immediately insert into the space between the temporary support and the cabin pre-prepared strip. For these purposes, is quite suitable scraps of boards. Such insurance will be useful in that case denied the Jack.
The Jack at the work place securely. Make sure that it rested against the solid wood, not rot.
Raising the structure to the desired height, angle the house build concrete platforms. On the grounds of the mold pillars of concrete with a height equal to the size of the new Foundation. It now remains to mount the rebar, set the formwork and pour the concrete. Updated the Foundation is ready.
