Earth-retaining structures hold back soil and water where the ground level is interrupted. For greater loads or deformation requirements, the structure is anchored. Strand anchors transfer forces in a controlled manner to a more stable soil layer, ensuring safety and longevity.
A retaining structure retains soil and (often) water along an excavation, embankment or watercourse. The structure fundamentally consists of a wall or element that absorbs the horizontal soil and water pressure and transfers it to the subsoil.
A freestanding wall is sufficient for limited turning height. For greater heights, higher loads or stricter deformation requirements, the structure is supported by an anchor system. The anchor transfers the horizontal tensile forces to a more stable ground layer behind the wall. Strand anchors are an efficient solution in this regard: high anchor force, slim profile and can be flexibly applied in temporary and permanent situations.
The anchor consists of an anchor head with wedges, a free length in a sheathing tube, and an anchored length that interacts with the subsoil through grouting. This way, the structure remains stable under both service and failure conditions.
The DeepPro strand anchor is an advanced anchoring system, designed for maximum reliability, durability, and efficient force transfer, using high-quality prestressing steel.
Thanks to multi-layer corrosion protection and innovative sealing systems, it offers long-term performance of up to 100 years and meets the strictest European standards for both temporary and permanent applications.

An anchored earth-retaining structure consists of three main components: a retaining wall, a load transfer element, and an anchor system that transfers forces to the ground.
The wall takes up earth pressure, water pressure, and surcharge loads. In wall constructions (sheet pile wall, combi wall, concrete wall), this happens via bending and clamping in the base. The horizontal tensile force from the wall is transferred via the anchor to a stable soil layer behind the active failure plane.
The load introduction takes place via a purlin, distribution beam or anchor plate, depending on the application. This distributes the concentrated anchor force evenly and prevents local deformations at the anchor head.

A retaining structure retains soil and water where the ground level is interrupted, for example during excavations, on slopes, or along water. Examples include sheet pile walls, combi-walls, quay walls, retaining walls, and cofferdams. For larger loads or deformation requirements, the structure is anchored with an anchoring system.
When a wall cannot independently absorb the occurring loads, or when deformations need to be limited. This is relevant for larger retaining heights, high soil pressure and water pressure, or with sensitive adjacent structures. The anchoring system then transfers the horizontal tensile forces to a more stable soil layer.
For virtually all earth-retaining structures where horizontal tensile forces need to be resisted, including quay walls, excavation support systems, slopes, embankments, retaining walls. The anchor system is identical; the chosen corrosion protection class and geometry depend on the application.
A sleeve anchor offers high holding power in a slim profile. This means fewer anchor points are required, making constructions stiffer and more efficiently designed, with work possible in confined spaces. The system is ETA-certified in all classes and suitable for both temporary and permanent applications.
In situations involving cathodic protection, track return currents, or stray currents, a metallic path via the anchor can cause corrosion or unwanted current discharge. An electrically insulated strand anchor (PL3) interrupts this path. Deepro is currently the only company in Europe to supply this with ETA certification.
