Quay Reinforcement

Project Background

The existing quay is currently being repaired as part of the development of the port on the site of the “Seine Parisi”
Marina in Cormeilles-en-Parisis, about 12 km northwest of Paris. Under the direction of the company BOTTE Fondations, the quay wall is being secured by means of 20 Ischebeck TITAN 73/45 self-drilling tension micropiles.

The challenge

Before the actual work on the new marina began, several buildings were constructed. This required the relocation
and structural reinforcement of an existing old quay wall. Due to insufficient knowledge of the construction of the
old structure, as well as the geotechnical properties of the subsoil, the Ischebeck TITAN self-drilling system was chosen as the appropriate solution.

The solution

The Ischebeck self-drilling system is particularly suitable for difficult geological subsoil conditions and in the case of challenging construction site conditions. Compared to conventional anchoring systems drilled using casing pipes, the process facilitates significant installation time and cost savings. This is achieved by drilling, injecting (dynamic grouting) and inserting the steel hollow bar simultaneously in one operation without the need for casing pipes. Finally, the head construction is embedded in the reinforced concrete beam.
