Subsequent foundation

Inside buildings, underneath power lines and bridges: the timely and budget-optimised re-foundation of existing buildings depends on various factors. Different ground conditions, load-bearing capacities and environmental conditions must be taken into account.

The spatial conditions are often a challenge when it comes to retrofounding structures that are worth preserving. However, with the use of specialised equipment, we are able to carry out subsequent foundations without any problems, even with limited construction heights, under power lines or bridges. Thanks to our extensive experience and careful preparation, planning and coordination of the various trades, PORR is your specialist for complex post-foundation projects.

We offer the following procedures for subsequent foundation:

• Bored pile under restricted height
• Steel pipe pile
• Micropiles
• HLV pile / ductile driven piles
• Jet grouting method
