Grouted anchors
Horizontal round steel tie rods generally represent the most cost-effective anchorage solution. However, if different boundary conditions, e.g. structures nearby, unsuitable soils just below ground level or refurbishment work on existing structures mean that horizontal anchors cannot be installed, then grouted anchors to DIN EN 14199 can be used.
ASF produce micropiles, which can be installed in changing subsoil conditions and various lengths and at various angles.
The anchor forces are dissipated via skin friction between the pile and the subsoil. In order to be able to assess the loadbearing behaviour of the piles, ASF recomended tensile tests to DIN EN 14199 and "EA-Pfähle" (German Geotechnical Society"Piles" committee recomendations).

In contrast to round steel tie rods, it is not necessary to carry out any excavation work to install anchor plates. A hinged joint is to be preferred to a fixed joint as the connection between sheet pile wall and head of anchor.; such a connection permits rotation, which compensates for deflection, settlement and installation conditions (see also EAU 2004)
ASF grouted anchors can be fabricated with and without upset ends to DIN EN 1993-5 in lengths up to 27m. Furthermore, each pile can be extended to any length by welding or with sockets. Yield stresses of min. 355 to max 590 N/mm2 can be guaranteed depending on the grade of steel.
In addition, any type of wall connection is possible, e.g. upset thread, eye rods or T-head joints.
