The prevalence of pile foundations has recently hit all records in the construction industry, and this applies not only to large companies, but also to individuals. The huge role in such “folk love” was played by the reliability and comparative simplicity of the design, which is famous for the pile-screw foundation. He also has disadvantages, but their advantages easily overlap. However, we offer to begin to deal with the most important basics.
A bit about stilts ...
Simply put, this design is a kind of pipe made of high-quality steel. Its ability to wrap itself in the ground is due to the presence of a special-shaped blade at the end. By the way, here we “caught” the pile-screw foundation: the drawbacks of such a design are that inevitably you will need
heavy equipment to screw the piles into the ground
, whose services have certainly not been called cheap recently. In addition, subject to heavy and rocky soils on the site, the price of this kind of work is likely to increase many times.
You will have difficulties with calculating the most important indicators in its design. Why? The data from the directories in this case will not help you, since you have to focus solely on specific indicators, constantly applying them in the calculations. And therefore, if you are not a mathematician, then leave the pile-screw foundation (the shortcomings of which we describe) to specialists who can calculate all the indicators with maximum accuracy.
And one more nuance. Many beginners make an extremely gross mistake. The point is that after deepening the piles into the ground, they should never be unscrewed, raising to the level you need. In this case, the fastening strength of the piles in the soil sharply decreases, so you should not engage in such risky experiments. However, the pile-screw
foundation, the calculation of the cost of which is best left to specialists, is not to blame for the lack of basic knowledge among builders.
We hope that you have not abandoned the idea of mounting this particular design, having read about its shortcomings? And very good, as we move on to its merits!
These include cost-effectiveness. Having performed even a rough calculation of the pile-screw foundation, you can easily see this. Experts say that resource savings (compared to other options) can reach 50%! And this despite the fact that for the construction of the same strip foundation in the same conditions, a monolithic slab may be required , the cost of which will further exacerbate the difference!
Add to this also the speed of work at which the above-described pile-screw foundation (the flaws of which already seem insignificant) can be erected in a few hours. Please note that after screwing the piles, you can start construction almost immediately, which cannot be said about the same tape type.
In addition, the participation of construction equipment (mentioned above) is limited only by the help when screwing the supports into the ground. Yes, there is virtually no directly excavation work , so you can also save a lot on the cost of excavator services.
