How to properly apply a jack for raising a house

Wooden houses are not only beautiful, they are alsovery warm and cozy. However, wood has one big drawback - it absorbs water well and therefore rot. Currently, all construction materials are impregnated with special preparations that ensure its safety for many years. But the houses of old buildings are not protected with such protection, and therefore the lower crowns are rendered unusable. In addition, all the wooden buildings give a strong shrinkage in the first two years, so the lower logs are much faster destroyed, regardless of whether you used special preparations or not. If you are faced with such a problem, then there is only one way out - to replace the lower rims. And for this procedure, you need a jack to lift the house.

First of all, it is necessary to understand whichtools and materials will be needed. In addition to new logs, support bars, construction and carpentry equipment, jacks will be needed to lift the house, namely jacks, in the plural. Some builders manage only one, but this requires some experience and theoretical knowledge: you need to know where and how to install equipment in order to avoid a skew. As general information, you can explain: one jack for raising the house is used alternately on all walls, raising the level no more than 6-8 cm at a time. Then you need to fix the upper logs on the uneven bars, after which you can move to the next wall. However, it must be understood that the whole house will be kept only on specially installed supports, without any backing. Therefore, some experts believe that the use of a single jack is justified only in one case - when it is necessary to raise the skewed to one side of the building. That is, in fact the lower rims are not built up around the house, but only from one or two sides.

How many jacks are needed? At least two, but preferably four - one for each corner of the house. Load capacity, depending on the weight of the house, according to the formula: the weight of the structure divided by the number of jacks, plus add a small margin, so that the equipment does not work at the limit of its capabilities. Now you need to prepare for them a place - cut openings in rotten logs to healthy wood. Equipment should be placed on a foundation or densely compacted soil, covered with a strong and thick board. Under the lifting head, it is better to put a thick plate of steel with a slight bulge, this will prevent slipping. The house should be lifted smoothly, all the time checking the level. Advice: do not determine the level visually and do not control it along the length of the extended rod, the jack for lifting the house is pressed into the bearing surface (board or ground), so this indicator does not reflect the objective picture.

It remains to clarify the answer to the last question: "Where to get the right equipment?" Buy two or even four jacks - very expensive, especially for a single operation. Well, one jack, let's say, is always useful on the farm, but where to use all four? That is why there is a rent of jacks for raising the house. The cost will be from 350 to 2500 rubles. depending on the carrying capacity, type and model. The price is indicated by the day. In addition, it is possible to order a special jack for raising the house. The price will be higher, about 15-20 thousand rubles. But such equipment has a number of advantages. Special jacks are designed specifically for this type of work, so do not slip, do not crumple the log, and there is no need to think through the technology itself, since such equipment is intended for building lifting from four sides at once.
