About the Technology:
This is one of the most reliable methods for installing bored piles, used in challenging geological conditions. The technology is based on the use of a telescopic Kelly bar, which transmits rotational force and axial pressure to the drilling tool, and a casing pipe that protects the borehole walls from collapse throughout the drilling and concreting process. This approach guarantees borehole stability in water-saturated, weak, or loose soils.
- Site Preparation
Marking the pile field and preparing locations for the drilling rig. - Installation of Casing Pipe
Driving the casing pipe to stabilize the walls of the future borehole. - Borehole Drilling
Excavating the soil with drilling tools using the Kelly bar. - Reinforcement Cage Installation
Placing reinforcement after reaching the design depth. - Pile Concreting
Filling the borehole with concrete mix while extracting the casing pipe.
Key Features and Advantages of the Technology
-
Absolute Waterproofing
The tight interlocking connection allows for the development of deep excavations below the groundwater level without the use of open dewatering or needle filter systems.
-
Capability in Complex Hydrogeological Conditions
The technology is indispensable when working in water-saturated, quicksand, and unstable soils.
-
High Load-Bearing Capacity
The alternation of soft and stiff piles with powerful reinforcement creates a monolithic wall capable of withstanding enormous loads from soil thrust and water pressure.
-
Minimized Dynamic Impact
Onboard electronics precisely control verticality and concrete volume, guaranteeing void-free filling and improving soil adhesion through pressure.
-
Versatility of Application
Secant piles can be used not only as temporary excavation shoring but also as part of the permanent building structure (e.g., diaphragm walls for underground parking or tunnels).

Prices
The cost of installing bored piles with a casing pipe depends on the diameter and depth of piles, soil characteristics, the volume of the pile field, and site conditions. The price is also influenced by the need for casing pipes, the type of drilling tools, and reinforcement requirements. To calculate the cost, results of engineering-geological surveys, pile parameters (diameter and depth), estimated foundation loads, and information about site accessibility for drilling equipment are required.

-
When is a casing pipe required?
A casing pipe is used in unstable or water-saturated soils where there is a risk of borehole wall collapse.
-
Can large-diameter piles be installed?
Yes. The technology allows for the installation of piles of significant diameter and depth.
-
Is the method suitable for dense urban development?
Yes. The work is performed without significant vibrations and can be used near existing buildings.
-
Can work begin without a finalized project?
With engineering geology data and load information, we can prepare a preliminary technical solution.
