Since its establishment in 2001 until today, Hidroinjekt Ltd. follows high standards for the implementation of large and small projects in the field of deep foundation. This is possible thanks to our highly qualified team of specialists and builders, as well as the modern equipment we have. Our company is relatively young, but the engineers working for us have more than 25 years of professional experience in this field.
The main criteria we follow in the implementation of each project are related to occupational safety, security after the project and cost optimization.
At the moment Hidroinjekt Ltd. ranks among the market leaders in its field. The share of the executed fortifications by building piles, diaphragm walls and anchors is especially large.
In the deep foundation we offer execution of piles (compacted, drilling – pouring, with or without siege, depending on the geology), as we have a full range of specialized equipment and facilities for the implementation of the above activities. We offer execution of piles with diameter from f350 mm to f1500 mm, with the maximum depth of drilling (including siege) up to 34 m.
The specialized technique for performing pilot foundations includes the smallest possible drilling machine in the range, which with its dimensions could easily work indoors. This type of drilling machine is also very suitable for piles foundation in indoor galleries, halls, production workshops, etc. Due to its compact size, it is very convenient when it has to be founded next to an existing building, for example.
Thanks to this machine we reconstructed an existing underground floor in the hotel “RADISSON SAS” – Sofia. With our largest drilling machine we achieve a maximum depth of foundation of 34 m, and in areas with weak geology and the presence of high groundwater we achieve this depth with siege. In this way the stability of the drilling is ensured until the reinforced skeleton is lowered and the pile is concreted. At this depth we also offer the largest diameter f1500 mm.
For reinforcement measures with diaphragm walls, we offer performance from a thickness of 400 mm to 800 mm, with a maximum depth of 36 meters. Diaphragm walls as a method for deep foundation are widely used in Bulgaria. They are very suitable for strengthening metro sections and metro stations, underground garages on several levels, pedestrian subways, and others.
The main advantage of diaphragm walls is the easy application of waterproofing directly on them after they have been excavated and milled. When making reinforcement by means of diaphragm walls, an inventory metal formwork can be used, through which a waterproofing strip is installed on the working joint between two adjacent lamellas and the watertightness of the pit is ensured.
Hidroinjekt LTD successfully completed a number of fortifications through diaphragm walls under the Sofia Metro Expansion Project, 2nd metro diameter and 3rd metro diameter.
Hidroinjekt Ltd. has extensive experience in strengthening through anchors. We perform IBO type anchors with carrying capacity up to 1200kN.
