The columnar foundation is most often completely replaced with a new one.

A foundation made of wood that has already been slightly damaged by fungus is usually replaced with a strip or columnar structure. To do this, the structure is raised to a certain level and concrete blocks or bricks are placed under it.

Strengthening the foundation of a wooden house
When repairing a foundation, it makes sense to immediately physician data it. This can be done if you are confident in the stability of the soil that is below the level of the foundation of your house. Reinforcing the structure under the building may also be required if you plan to add another floor to the house, but there is a suspicion that the previously installed foundation will not withstand the increased load.


There are two ways to strengthen a foundation, depending on the load it will have to bear.

Instructions for strengthening the strip structure
To make the foundation more durable, the following work is carried out:

A trench is dug around the perimeter of the foundation. The hole should be wide, otherwise it will be inconvenient to work. In addition, it should be taken into account that the new foundation will be stronger.
The soil is cleaned from the excavated foundation. A wire brush is used for this.
The trench should be wide enough to allow comfortable work.

In the old foundation, holes are made with a drill. It is important that their diameter exceeds the thickness of the purchased reinforcement bars by no more than 1 mm. In this case, the metal elements will be installed securely and without gaps.
Reinforcement bars are inserted into the drilled holes using a hammer. They will help connect the new foundation to the old one.
Reinforcement bars are driven into the drilled holes, to which the vertical grating is attached.
