Tangent pile wall

tangent pile wallA tangent pile wall is a special construction method used in civil engineering to build retaining walls, excavations and foundations. The construction consists of a series of bored piles that are driven into the ground so closely together that they touch at the edges but do not overlap. This arrangement results in a stable and load-bearing wall. However, it is not completely watertight. This type of pile wall is often used in areas where stability and load-bearing capacity are required, but complete impermeability is not necessary. The tangential arrangement of the piles creates a robust wall structure that can withstand high loads and is well suited for a variety of construction projects.

Areas of application

Construction pit enclosure

tangential retaining wallTangent pile walls offer high stability and are sufficiently permeable to water, making them ideal for excavations where complete impermeability is not required. They prevent earth from slipping and ensure safety in the excavation pit. They are also a good solution in confined spaces.

Sound and noise barriers

tangent pile wall for noise protectionTangent pile walls are often used in urban areas as sound and noise protection measures. They form high, stable walls that can effectively serve as barriers against noise. Thanks to their robust construction, they can significantly reduce the noise level in neighbouring residential or commercial areas and thus contribute to improving the quality of life and work.

Retaining walls

Pile wall tangent

Tangent pile walls can absorb high lateral earth pressure forces and are ideal for securing slopes and embankments. The tangential arrangement of the piles creates a stable and load-bearing structure that prevents landslides and erosion. These walls make it possible to safely shape steep terrain cuts and make areas on slopes usable. They offer a long-term solution for stabilising slopes and can be flexibly adapted to different geotechnical requirements.


⇒ High load-bearing capacity and stability

⇒ Flexibility in the design

⇒ Use in confined spaces


⇒ Not completely waterproof

⇒ Time consuming

⇒ Cost-intensive depending on the construction project/requirements

Pile breaking of a tangent pile wall

One method that can be used to process tangent pile walls is the Brextor® -Method. However, Brextor® can also be used to process all other types of pile walls, regardless of whether they are secant or contiguous.

Brextor® offers you the following advantages:

🏗 Increased construction quality

Perfectly cut piles without cracks in the pile body or spalling on the pile outer skin, no bent or torn reinforcements and a height accuracy of +/- 1cm.

💵 Reduced construction costs

The demolition material consists of 80% gravel 0-30mm and can therefore be reused directly on the construction site. In addition, Brextor® requires less working space than conventional mining methods. This means that not only expenses for transportation and disposal incl. fees are saved, but the purchase and supply of replacement material is also eliminated. Furthermore, the preparatory work eliminates the need for a separating diamand cut at the final extraction level and the cleaning effort is massively lower than with conventional extraction methods.

Shortened processing time

For example, a pile with a diameter of 1 m and a height of 1 m can be processed within 40 minutes. A daily output of up to 16 piles is possible. In addition, Brextor® provides reliable performance and therefore increased planning security.

♻️ Environmentally friendly

With Brextor®, the demolition material (80% gravel 0-30mm) can be reused directly on the construction site. In addition, Brextor® requires less working space. This saves excavation and replacement material. Due to the direct reuse of the demolition material on the construction site and the saving of excavation and replacement material, transports can be saved. In addition, landfills are less burdened.

👷 Increased health & safety at work

No heavy physical work is required for pile cutting, which massively reduces the risk of health hazards such as HAVS syndrome. In addition, Brextor® avoids working in danger zones.
