Screw piles for foundation

When building a house, he turned to the company Piles NOVA. Their products are an excellent alternative to both flood-in foundations and bored piles and block foundations. Using them in the construction of his house 6x6 m received several advantages. Firstly, the device, which included marking on the site, twisting the leveling and pouring with concrete took only one day. After the concrete has dried, the shelves are welded onto which the strapping is laid and the entire foundation is ready for erection.

Secondly, the cost of such a design is 2-3 times lower than the cheapest ribbon shallow or 1.5 times lower than the column foundation comparable in bearing capacity and strength.

The main disadvantage is a service life of 50 years and a high sensitivity to corrosion processes. It is necessary at least once a year to process the ground part of the pipe with anticorrosive mastics.

Sensitivity to corrosion

They built a frame house 8.5 x 9 m in size. As a foundation, 26 piles of 108 mm diameter were installed. So, the KK soils at the construction site are heterogeneous, the depth of the piles of the bel is different from 1.5 to 2.5 m. The piles were screwed according to the technology - with a machine, and not manually, checked everything according to the level, concreted itp. Before concreting, they cut one level, and after pouring, round heads were installed - they were not welded. The harness was made with a simple wooden beam 150x150. The frame has additional jibs for stiffening. Inside the frame is taken up with a raised beam, And outside the plywood is full. Roofing of flexible tiles on upholstered logs. The whole problem is that the house is quite tangibly swaying especially felt on the second floor. At first, the builders claimed that this was due to the lack of cladding on the frame. But after her stuffing it only got worse.

Low reliability of spatial design

Screw piles are a very convenient building structure, which can really simplify life when building a foundation. Or it can shorten the life of the building if you greed and buy products from nuggets that rivet piles on the knee without recognizing any standards. However, factory production is not a guarantee of quality. When I chose piles for a bath, I was not too lazy to go to the factory to see their products. With pleasure they showed the whole nomenclature and even gave a peek into the anti-corrosion treatment workshop.Since this is the “thinnest” place of metal screw piles, I paid special attention to him. Everything turned out to be just fine and in compliance with surface cleaning technologies and the Hempel coating itself is a modern anticorrosive substance. And the friendly attitude to the client, despite the fact that my order was miserable only 6 small piles.
