Our developments

The main developments of the VIF enterprise in the construction of foundations

   1. The invention of new, Effective piles of SV type, SVD – (Application in construction according to registered TU with 1991 year).

Benefits:

• Bearing capacity of one m3 Effective driven piles in 1,5-4 times higher, in relation to conventional driven or rammed piles;

• Work on vertical pile shaft, horizontal and pull out load at the same time;

• Decrease building sediment to 60%;

• Effective piles immersed by indentation methods, driving or by vibration immersion.

These piles are also used as structural elements in the construction of retaining walls, when fencing pits, while strengthening the embankments and the construction of berths.

Piles are recommended to be used in all types of soils, especially on weak water-saturated soils, under buildings and structures, that transmit vertical, inclined and pull-out loads.

   2. Invention of the technology and principle of pile driving by the indentation method, 1994 g.

   3. Invention, design, implementation and production Pile driving devices type PV – (currently invented 7 modifications). Start of using the first Devices on site – with 1996 g.

Benefits: 

• the high quality and reliability of the foundation grounds, as the shaft of the submersible pile is formed in the factory, therefore, it has the best performance, than the trunk or CFA bored piles, which are formed at a construction site;

• Leaning on a compacted soil base of pressed piles is stronger and more reliable than relying on a natural soil base of drill piles;

• Significant cost savings using pressed piles are formed on construction sites composed mainly of clay soils with an arrangement of groundwater level at depth 0,5-8,0 m. from the natural ground, as well as at the sites, composed of weak and soil subsidence.

   4. InventionEffective structures for retaining walls (Use according TU)

   5. Invention Stand for static tests of piles (Application to 2014 city)
