Sheet pile constructions are widely used for excavation support, quay walls, and infrastructure projects. On this page, you can read how sheet piles work, when anchoring is necessary, and why strand anchors are an efficient solution for sheet pile anchoring.
A sheet pile wall is a widely used earth-retaining solution for construction pits, quays, and excavations. The selection of the correct sheet pile profile, the method of sheet pile installation, and the anchoring of the sheet pile wall collectively determine the safety, deformation, and feasibility of the structure.
For larger loads and deeper excavations, a freestanding sheet pile wall is often insufficient. In these cases, a anchored sheet pile construction is chosen, where an anchor system transfers the forces to a more stable subsoil.
Within these types of constructions, strand anchors play an important role. These offer an efficient and technically robust solution for sheet pile anchoring, for both temporary and permanent applications.

Other solutions and applications
A sheet pile wall is used to safely retain earth and water for building pits, trenches, quay walls and infrastructural works. When installing a sheet pile wall, steel profiles, also known as sheet piles, are driven into the ground to create a continuous earth-retaining wall.
Depending on the excavation depth, soil pressure, water pressure, and surrounding loads, a freestanding sheet pile wall is not always sufficient. In that case, a anchored sheet pile wall is chosen.
Strand anchors are an efficient solution for this, particularly with larger loads and deeper excavations. Compared to other solutions, such as strutting frames or traditional anchor systems, strand anchors offer several advantages:
This makes a sheet pile solution with strand anchors not only structurally strong, but also practical and economically attractive.
When installing a sheet pile wall, several factors determine the functionality of the structure:
The choice of the correct execution method has a significant impact on the environment and the construction.
The construction of a sheet pile wall begins with the selection of profile type, steel strength, sheet length, and driving depth. The sheet piles must have sufficient stiffness and moment capacity to withstand soil pressure, water pressure, and loads from traffic or adjacent structures.
For greater excavation depths, an anchored sheet pile wall is usually employed to limit the bending moment in the wall and reduce horizontal deformations.
An anchored sheet pile wall consists of:
In strand anchors, the load is transferred to the wall via the anchor head and the purlin. The anchored part of the anchor then transfers this force to the stable subsoil.
When designing and installing a sheet pile wall, therefore, attention must be paid not only to the wall itself, but also to:

A sheet pile wall is an earth-retaining structure used to contain soil and water, for example in construction pits, quay walls and infrastructure projects.
The wall is constructed from profiles, also known as sheet piles, which are driven into the ground and interlock with each other.
Depending on the load and application, a sheet pile wall is constructed as a free-standing system or as a anchored construction in combination with an anchoring system, such as a tie rod anchor.
A sheet pile structure absorbs soil pressure and water pressure via the sheet piles. The wall is installed in the ground by pressing, vibrating or hammering, depending on the soil composition and environmental factors.
In the case of larger loads, the sheet piling is anchored with an anchor system. The forces are then transferred via the sheet piling and a purlin to the anchor, which diverts them to a more stable soil layer.
Sheet piles are the individual elements that make up a sheet pile wall. The profile of the pile allows them to interlock, forming a closed, earth-retaining wall.
There are various types of sheet piling, such as:
The choice of sheet pile type is determined by factors including loads, soil composition, water pressure, and the desired service life of the structure.
An anchored sheet pile is used when a sheet pile cannot withstand the occurring loads on its own. This is particularly the case with:
By applying an anchoring system, such as strand anchors, the structure can be designed to be stiffer and more efficient.
Tension anchors are widely used for sheet pile anchoring due to their high capacity and efficient operation.
Key benefits include:
Additionally, Deepro strand anchors are supplied as a complete system, with all components matched to each other.
