Anchor equipment
Regardless of the anchoring method, anchors are essentially differentiated by their function: temporary anchors with a maximum service life of two years, or permanent anchors that meet higher requirements for corrosion protection as a priority.
Anchoring systems that do not need to be drilled, driven, or installed using other machinery are especially cost-effective. Just due to the high intrinsic weight alone, hoisting equipment is needed to handle them.
If there is enough space and earthworks are not a problem or are not necessary at all, then horizontal systems are usually the optimal solution.
The solution for sheet pile walls: round steel tie rods
An anchorage employing round steel tie rods is an economical solution for securing a sheet pile wall, which can be adapted to suit the situation. The forces acting on the wall are transferred via the waling to the round steel tie rods and then to the anchor plates or walls. The selection and design of the anchoring structure is done in accordance with static and structural requirements.
Upon request, we can supply a complete package from one source, consisting of the supply and installation of all the anchorage elements and accessories required for sheet piling structures. Apart from anchors and anchor parts, anchor connection elements, walings and waling fixings, sheet pile wall capping beams, recesses, ladders and mooring lugs plus bollards and special components are also part of our range.
Applications
- Cofferdams
- Ports and harbors
- Waterways

Maximum loading capacity, minimum diameter: thyssenkrupp ASF drilled injection pile system
Micropiles are being increasingly used as traction elements in water construction and marine projects, gradually replacing driven pile systems. Further development of drilling technology has contributed greatly to this.
thyssenkrupp ASF drilled injection piles are a micropile system that conforms to DIN EN 14199, which thyssenkrupp Infrastructure developed in collaboration with special civil engineering companies as a pull/push and interchangeably loaded pile system.
This system is a further development of existing pile systems. thyssenkrupp ASF drilled injection piles have high internal load-bearing capacities and reserve capacities as well as being very robust and low warpage. This is achieved by using good-quality steel in accordance with DIN EN 10025. The Withworth threaded connection on the shaft of the pile can be used to easily adapt other components such as socket joints, turnbuckles, or Cardan joints.
This development is based on experience from over 30 marine and water construction projects with approx. 50,000 drilled meters.
Applications
Foundation piles
Bracing in marine and special civil engineering
Bracing in waterway expansion
Advantages

The economical system:
TITAN micropile
Micropiles are non-prestressed pile elements with a diameter < 300 mm. Various types are available. They are especially popular for strengthening or underpinning existing foundations and transfer the tensile and compressive forces into the subsoil. Depending on the application, micropiles can be loaded in tension only, but also in tension and compression. We can supply appropriate solutions.
TITAN micropiles are governed by the general technical approval Z-34.14-209 granted by the Deutsches Institut für Bautechnik (DIBt). They are micropiles (compound piles) for which the stipulations of DIN EN 14199 in connection with DIN SPEC 18539 must be observed, unless otherwise specified in the approval.
Advantages
- Can be adapted to any load profile
- Short execution times
- Can be used with any drilling equipment
- Can be used as pull and push piles
- Low settlement when used in foundationswith pressed piles
Micropiles: loaded in tension only
A micropile is a continuous steel tendon that is inserted into the subsoil. Pressure grouting produces a body of grout at the bottom end of the steel tendon. This grout is connected with the part to be anchored by the steel tendon (unbonded length) and the anchor head. Loads are transferred to the ground via skin friction over the defined anchorage length.
Applications
Applications
- Anchoring in tunnel construction
- Tunneling under rail embankments
- Anchoring of ramps
- Horizontal high-pressure grout injection for pipe umbrellas in tunneling
- Shear reinforcement of pier noses
- Stabilization of trouble zones with polyurethane systems e.g. tunneling
- Slope stabilization at tunnel entrances
Micropiles: loaded in tension and compression
Here, a continuous steel tendon is surrounded over its full length in the ground by the cement grout injected subsequently. The force is transferred via the combination of tendon and grout along the pile’s full length. The load is transferred into the subsoil by means of skin friction. The micropiles can be drilled either vertically or at an angle and are generally loaded axially.
Applications
- General excavations
- Anchoring of retaining walls
- Underpinning/strengthening of bridge foundations
- Uplift protection
- Road widening
- Reinforcing of bridge abutments
- Refurbishment of bridge piers and port areas
- Foundations of electricity pylons, transmission masts, wind turbines
- Overhead line masts for railways
- Noise protection barriers
- Avalanche protection
Versatile anchor for every terrain: TITAN soil nail
Soil nailing is a method of improving the natural stability of the soil. Soil nails in accordance with DIN EN 14490 increase the cohesion that is lacking in loose material. They also enhance the tensile and shear strength of such soils, thus creating a new composite material with a high load-carrying capacity. The soil must exhibit an adequate minimum stability for site operations.
Applications
- Slope stabilization
- Excavation shoring
- Refurbishment of unstable slopes and hillside roads
- Retaining walls
- Foundations for rockfall nets
- Strengthening the permanent way
- Made embankments
Advantages
Stabilizes embankments and prevents settlement Ideal for steep slopes because soil nails can be installed in 2 or 3 m lengths with lightweight drilling rigs Flexible, environmentally friendly method of construction suitable for any terrain Ideal for existing structures such as walls or stocks of trees that are to be incorporated into new construction works Minimal vibrations Little noise Cost-effective method for temporary and permanent applications
Safe anchorage of high tensile forces: driven anchor piles
Our driven piles for anchoring are used in the construction of quay walls.
Additional warpage can essentially increase the load on the piles, so that the maximum load is sometimes not on the head of the pile but rather behind the sheet piling. This must be taken into account when installing the piles and the pile connection.
Applications:
- Quay wall structures
The benefits of slow-action hammers
The benefits of fast-action hammers
In principle, additional deformations cause an increase in the stresses in the pile, which in some circumstances means that the maximum axial force occurs not at the head of the pile but behind the sheet piling. This must be taken into account when designing the piles and the connection to the wall.
Tie Back Systems
Round Steel Tie Rods
An anchorage employing round steel tie rods is an economical solution for securing a sheet pile wall, which can be adapted to suit the situation. The forces acting on the wall are transferred via the waling to the round steel tie rods and then to the anchor plates or walls. The selection and design of the anchoring structure is done in accordance with static and structural requirements.
Round steel tie rods are preferably installed horizontally or with only a shallow inclination because otherwise if the anchor wall is very deep, large quantities of soil must be excavated for the connection to the anchorage.
