Patented FTP pile system
An OlivierĀ® pile is a patented drilled displacement pile made of concrete or reinforced concrete with a screw-shaped shaft (helical shaft) which is performed without soil removal. Due to its screw-shaped shaft, the Olivier pile is particularly suitable for use in soils with low load-bearing capacities, such as clay and loam, but can be applied in almost all types of soil. ontrary to traditional FDP piles, the Olivier pile is 100% displaced until the bottom of the pile and no soil is transported to the surface. An Olivier pile can be made with any foundation machine with a minimum torque from 10t/m.

The new Olivier coupling, available for pipes starting at 133mm (5ā¼), addresses several drawbacks of the classic version. It eliminates the need for screws and matches almost the same diameter as the drilling pipe. The inner diameter remains unchanged from the classic coupling. Additionally, the plugs have been modified and rounded to fit the couplingās radius. These improvements result in a significantly reduced wear factor compared to the classic Olivier coupling. Due to the absence of screws, there is no longer a threaded hole in the male side. This means that the interior of the male part is now completely sealed. The new Olivier coupling is available in two versions: with 8 plugs and with 16 plugs. The choice depends on the specific application and the required drilling torque.
