Technology
Dynamic development of the construction industry in Russia and an infill construction in major cities require the use of new high-tech methods in the field of underground construction works.
Technologies
Using “Atlant” anchor piles includes the following technological stages:
1. Drilling a hole until a design reference mark with the use of cement grout in which the water-cement ratio is equal to 1.0. Here the cement grout performs two functions: first, it’s a drilling grout that transports particles of eroded soil to the surface; second, the cement grout functions as an injecting grout that fills all the hollows and cracks as well as spreading into the soils surrounding the pile.
2. Pressuring the hole with a thicker cement grout where the water-cement ration is equal to 0.4 – 0.6. Thus, in the process of pressuring there is a forming of a cement stone enclosure that is very durable.

Technology advantages
- All the stages of the process can be performed simultaneously, i.e. drilling a hole, building the body of an anchor pile, and reinforcement made at the same time.
- Whole performance takes about 5 – 10 times higher comparing to using traditional boring piles or soil anchor constructions.
- This technology provides an opportunity to build anchors and piles in unstable soils without using casing.
- This technology provides an opportunity to use small-sized drilling units to underpin foundations from building basements and small underground constructions.
- There is no negative impact on existing building foundations.
- This technology allows to work in factory floors without stopping the production process.
- This technology cuts the expenditure on hand labor.
