How to raise a house on the foundation

It became necessary to raise the bath or house to restore or replace the foundation? It is not worth a hurry to hire builders brigade, it is possible to save money and nerves. Two people calmly cope with this work.

Before proceeding with the rise, we disassemble all the extensions to the house that prevent free access to the foundation of the building throughout its perimeter. In order not to destroy the furnace and the pipe, partially disassemble the floor and roof around them. Also, if possible, remove the doors and windows.

For lifting a log, we use hydraulic or mechanical screw jacks, the load capacity of which is 5-10 tons (it depends on the size of the house). For jacks, we prepare strong horizontal sites so that they do not push into the ground. The more their reference square, the better. Between the logs of the lower crown and the pyatkom of the jack, put the steel plate to protect these logs from the deformation. It is important that the wood in this place is strong and dry.

To control the height of the lift, we use a hydraulic level - this is a long transparent tube filled with water. In this capacity, an opaque hose can also be used if inserting glass tubes with a length of 20-25 cm in both ends. Each corner of the house in the ground drive two rails, to one of them we cling one end of the hydraulic level, and the other end we apply to the rest of the slats and We note on them changes in lifting height.

We support the corner of the house of a couple of jacks. Gently raise it in about two centimeters. Based under the temporary support, the gasket is required in this case thickness.

We proceed to the next corner and repeat the entire sequence of actions. Especially just lifting the angle, if he has already moved away from the old foundation. Special attention is paid to raising the last angle, since the whole house is already standing on the backups and any of the corners may unexpectedly get off the lining. Also watch the jack not twisted.

Temporary supports at home is better to put on concrete sites, otherwise they can give uneven sediment. When the house is raised to the desired height, align it by hydrorem. After that, proceed to the reconstruction of the old foundation or the construction of a new one.

The process of raising the house on the foundation is painstaking work that does not tolerate a rush. It is important to follow the instructions and perform all safety rules. Otherwise, not only distortion is possible, but also damage to the health of the builder.
