How to properly apply the jack for raising the house

Wooden houses are not only beautiful, they are also very warm and cozy. However, wood has one big drawback - it absorbs water well and therefore rot. Currently, all building materials are impregnated with special preparations that ensure its safety for many years. But the houses of the old building are not protected with such protection, and therefore the lower crowns are in disrepair. 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 which tools and materials will be needed. In addition to new logs, support bars, construction and carpentry equipment, jacks will be needed to raise the house, namely the 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 the equipment to avoid a skew. As a 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, one must understand that the whole house will be held only on specially installed supports, without any back-up. 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. The lifting capacity depends on the weight of the house by 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. The equipment must be placed on a foundation or tightly compacted soil, covered with a solid 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 find out the answer to the last question: "Where to get the right equipment?" Buying two or even four jacks is very expensive, especially for a one-time operation. Well, one jack, suppose, is always useful on the farm, but where to use all four? That's why there is a rental 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 logs, and there is no need to think through the technology itself, since such equipment is designed to lift buildings from four sides at once.
