We provide a comprehensive range of anchors and accessories to meet diverse challenges (quay structures, onshore and offshore wind turbine foundations, tunnels, excavations, retaining walls and slope stabilization).
In terms of construction, a pile foundation is a type of deep foundation that enables the loads of structures to be transferred to deeper, more stable layers of soil. When constructing a pile foundation, piles (also known as pilots) are drilled or rammed into the soil until a sufficiently stable layer of soil or stone has been reached. The load of the structure is then firstly transferred through the friction of the piles with the soil (skin friction) and secondly via the point-bearing pressure of the piles.
Irrespective of the type of anchor, we make a fundamental distinction between two types of anchor, according to their function: temporary anchors, which are usable for a maximum of two years, and permanent anchors, which primarily meet higher standards of corrosion protection.Anchor systems that do not require drilling, driving or other equipment for installation are particularly cost-effective. Equipment is only required for handling, due to their high weight. If enough space is available and any earthmoving is straightforward or necessary anyway, these usually horizontal systems are the ideal solution.
TK-ASF drilled injection pile
TK-ASF drilled injection pile is the name of the new micropile developed by thyssenkrupp Infrastructure in collaboration with specialized civil engineering companies. The advantages of the new TK-ASF drilled injection pile are low deformation and high strength. The use of easy-to-process steel grades also results in high load reserves between yield strength and tensile strength amounting to approx. 25 to 30 percent. This safety concept makes the system attractive for construction clients and engineering firms.
Certified to EN 14199:2012-01 in conjunction with DIN SPEC 18539:2012-01, these piles can be produced ex works with or without upset ends in lengths up to 32 metres. They can be combined to any required length by welding or with coupler connections.

Injection pile – stressed in tension only
An injection pile is a continuous steel tendon that is installed in a cavity in the ground. The injection of cement produces a body of grout in the rear section of the steel tendon. This grout is connected with the part to be anchored by the steel tendon (free anchor length) and the anchor head. Loads are transferred to the ground via friction in the area of defined grout length. The injection piles are stressed in tension only and pretensioned.
Injection pile – stressed in tension and compression
The continuous steel tendon and the subsequently injected cement grout surround the steel tendon over its entire length in the ground. The force is transferred via the combination of tendon and grout along the full pile length; load transfer into the soil is by means of friction. The injection piles are constructed either vertically or at an angle and are generally stressed axially. Injection piles are not pretensioned and can be stressed in tension and compression.
TITAN soil nails
Soil nailing is a method of improving natural soil stability. The soil nails improve the cohesion of loose material and increase its tensile and shear strength, producing a new composite material with high load bearing ability. Soil nails can absorb tensile and transverse loads. They create a monolithic body displaying high stability. The softer the soil, the closer the nails have to be spaced.

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.
