About the Technology:
Secant piles (BSS) is a technology for constructing a continuous wall in the ground, used for excavation shoring, waterproofing, or foundation reinforcement. The structure consists of a continuous row of vertical reinforced concrete elements created by sequential drilling and concreting of boreholes with mandatory interlocking. The result is a monolithic and waterproof wall.
- Site Preparation
Marking the wall axes and preparing locations for drilling equipment. - Installation of Primary Piles
Drilling and concreting piles that form the base of the future wall. - Installation of Secondary Piles
Drilling piles between the primary ones with partial intersection of their bodies. - Reinforcement Installation
Placing reinforcement cages in the design piles. - Formation of the Shoring Wall
Obtaining a continuous structure capable of withstanding soil and water pressure.
Key Features and Advantages of Secant Pile Technology
-
High Rigidity of the Shoring Structure
The monolithic interlock of piles creates a reliable "shield" capable of withstanding soil pressure and preventing landslides during construction.
-
Reliable Performance in Water-Saturated Soils
The continuous pile wall acts as a powerful hydro-barrier, cutting off moisture and providing comfortable conditions for dry construction in any season.
-
Wide Construction Capability
The compactness of drilling equipment and the absence of impact loads allow excavation shoring to be built right next to existing buildings and utilities.
-
Possibility of Constructing Walls of Significant Depth
Our equipment allows confident work at great depths, ensuring reliable shoring even for large-scale projects.
-
Minimal Vibration Impact on Surrounding Buildings
The non-impact drilling technology preserves their integrity — no vibrations or dynamic loads.

Prices
The cost of installing secant piles depends on the depth of the structure, pile diameter, soil characteristics, and the scope of work. Reinforcement requirements, equipment access conditions, and the need for additional dewatering or soil stabilization measures also significantly affect the price. To calculate the cost, a design for the excavation shoring or initial data are required: results of engineering-geological surveys, excavation depth, pile parameters, and site conditions.

-
When are secant piles used?
The technology is used in the construction of deep excavations, underground parking garages, and other underground structures.
-
Can the method be used near existing buildings?
Yes. Secant piles are installed without significant vibrations, allowing work in urban areas.
-
Is a design for the excavation shoring required?
It is desirable. However, with geological data and site parameters, we can develop a technical solution.
-
Can such piles be used as part of a permanent structure?
Yes. In some projects, the secant pile wall serves as a permanent retaining or shoring structure.
