Special civil engineering

Both deep and secure.

Special civil engineering is a task for true specialists with strong accountability. Precisely coordinated procedures for foundations, underground sealing, and securing rock, slopes, and buildings must take into account the respective soil conditions as well as the intended use. With experienced teams PORR satisfies particularly high requirements for reliability and versatility.

Furthermore we also develop groundbreaking special procedures. The “Stump Jetting” procedure, for example, ranks among cutting-edge technologies. The “Frankipfahl”, together with the “Franki-Ramme”, provide especially strong advantages where heavy loads are to be removed or where the stable building site is deeply located. Support and anchoring with micropiles is another important part of our special civil engineering. And within a city where there is increased traffic volume above and below ground, confined spatial conditions require particular expertise.
