Building a house is a real art. But not a single master’s work can be created without some foundation. In paintings, this is canvas, but in the case of construction - the foundation. Not only the longevity of the building depends on its strength, but also the safety of those who live there.
Unfortunately, the realities of our time are such that private developers are forced to save on everything, if only to somehow reduce the cost of construction. That is how the foundation appeared on
screw piles. Reviews indicate that in most cases it can be a pretty good alternative to other construction methods.
Bit of theory
Of course, the construction of houses on stilts has been known for a very long time. Once upon a time, our distant ancestors were engaged in it, putting their houses on piles where it was not possible to erect a more monumental building.
Of course, modern specialists could not ignore this method of construction. So, they developed a technology by which piles are made of stainless steel, which in their action are similar to huge screws. Such a foundation on screw piles (reviews about it, however, are rather contradictory) are literally screwed into the ground, installing a house on it.
What's wrong?
As we said, there are different reviews. Let's figure it out. Some customers say that the stilt house gradually begins to settle or squint on one side. What is the reason for this? As a rule, this is the result of improper or completely absent geodesy.
If sand or something similar is located under a layer of dense and heavy soil, then small piles, even if they were dug almost all the way, cannot serve as a really reliable foundation for construction.
In addition, the quality of such a structure as a foundation on screw piles (reviews often say this) directly depends on the skill of the working team. It is difficult to spoil the same tape base: if normal cement was used, then in any case everything will be in order. But with piles everything is not so simple.
Construction flaws
If you notice that the piles swing after they are screwed in, then you can not put a house on them. It would seem that it’s not even worth talking about, but there are so naive customers who believe all the tales that the builders tell them.
They dig a pit almost for the full length of the piles, screw in the remainder, after which they fill up and tamp the pit. Of course, feedback on their work can hardly be called positive. Remember that the foundation on screw piles (the reviews of which we are considering) is called "screw" for a reason. Piles need to be twisted into the soil, not buried!
Other claims are related to the economy of the customers themselves. They do not want to spend money, relying on chance. In simple terms, the average foundation on screw piles, the calculation of which should be carried out only by specialists, involves the installation of an average of 8-9 piles on a house 6x6 meters. So, put it on 4-5 is not necessary. Over time, the bearing capacity may not be enough, after which the building will "lead".
Conclusion
Otherwise, all the reviews are positive. People say that only because of the cheapness of this method could they meet a small budget. So the installation of the foundation on screw piles is ideal for low-rise construction.
