No house can be built without a quality foundation. But it happens that the soils on the site are too unstable, and therefore it is simply impossible to fill in a classic tape or even a monolithic base.
In such cases, screw piles can be an excellent way out, reviews of which we will consider today.
What is this?
Before we talk about the positive and negative feedback about this technology, it would not hurt to know the essence. So, the foundations on screw piles essentially resemble a kind of "hut on legs". Special piles made of high-quality steel grades are screwed into the ground, on which a grillage is mounted on top. In some cases, the house is placed directly on them.
From this property follows the first positive aspect that distinguishes screw piles: reviews indicate that it takes very little time to install such a base. In any case, it is disproportionately less than such an operation would take if you fill in a monolithic foundation.
What kind of houses can I put on them?
Sorry,they also have their drawbacks. First of all, experts still do not advise building "palaces" on them, since the bearing capacity of piles may not be able to cope with such a mass. In this regard, I would like to say that most of the negative reviews are related precisely to the fact that homeowners did not heed the recommendations of construction companies.
This is especially true for cases of construction on unstable soils: screw piles, reviews of which are very contradictory, still cannot be compared with a monolithic concrete pad. It is best to put small country cottages or even bathhouses on them.
Installation conditions
It should be noted that some of the negative opinions still have a real basis. First of all, this concerns the construction equipment used.
If you are going to build something big enough, you will have to order massive piles. They are not only difficult to lift if the road to the construction site is washed out, but also difficult to screw into the ground. For this, powerful construction equipment is used, the rental cost of which can hardly be called low.
However, it is not so much the screw piles themselves that are to blame, reviews of which we are considering, but gullible customers and cunning builders.
The latter like to talk about the speed of installation and other positive things, forgetting to mention the need for a normal access road, the presence of an electrical network of at least 5kVA (for welding), and also enough water to pour the concrete base.
Agree that when concluding an agreement with a normal company, you will definitely not have such problems.
Mistakes at work
Shoot away the workers of that company who are starting to manually dig pits for screw piles! The reviews of the owners of such "long-term construction" indicate that complete nonsense is obtained. We remind you of the technology: the base is screwed (!) into the ground, which ensures the stability of the finished building. If you dig holes under them manually, twist and unscrew the rods several times, then nothing good will come of it!
Now let's talk about the financial side of the issue. Three or four screw piles for the foundation, the price of which will be about 1600 rubles per piece (diameter 89mm), will not cause serious damage to your budget.
