Foundation on screw piles: reviews and practical application

Building a house is a real art. But no masterpiece can be created without some basis. In the paintings this is a canvas, but in the case of a building - the foundation. From its strength depends not only the longevity of the building, 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. This is how the foundation for screw piles appeared. Reviews indicate that in most cases it can be a very good alternative to other construction methods.

A bit of theory

Of course, the construction of houses on stilts is known for a very long time. Once they were engaged in our distant ancestors, putting their houses on piles where there was no possibility to erect a more monumental building.

Of course, this method of construction could not bypass modern specialists. So, they have developed a technology in which high-quality steel is used to make piles that are similar in their effect to huge screws. Such a foundation on screw piles (reviews about it, however, are quite contradictory) are literally screwed into the ground, installing a house on it.

What's wrong?

As we have already said, there are different opinions. Let's figure it out. Some customers say that the house on stilts is gradually settling or squinting on one side. What is the reason for this? As a rule, this is the result of inadequate or completely absent geodesy.

If there is sand or something like that under the layer of dense and heavy soil, then small piles, even if they are stuck almost to the limit, can not serve as a really reliable basis for construction.

In addition, the quality of such a structure as the foundation on screw piles (reviews often speak about this) directly depend on the skill of the work team. It is difficult to spoil the same tape base: if normal cement was used, in any case everything will be in order. But with the piles everything is not so simple.

Defects of construction

If you notice that the piles swing after they are screwed, you can not put a house on them. It would seem that this should not even be said, but there are so naive customers who believe all the tales that builders tell them.

They pull out the foundation pit almost to the full length of the pile, twist the remainder, and then fall asleep and ram the foundation pit. Of course, feedback on their work can hardly be called positive. Remember that the foundation on the screw piles (the reviews we are considering) are called "screw" for good reason. I need to spin the sow into the soil, and not bury it!

Other claims relate to the economy of the customers themselves. They do not want to spend money, relying on a chance. In simple terms, the average foundation on screw piles, the calculation of which should only be carried out by specialists, involves the installation of an average of 8-9 piles per house 6x6 meters. So, it's not necessary to put it on 4-5. Over time, the bearing capacity may not be sufficient, after which the construction will "lead".

Conclusion

Otherwise, all the reviews are positive. People say that only thanks to the cheapness of this method they were able to keep within a small budget. So installing a foundation on screw piles is an ideal option for low-rise construction.
