Low-noise and vibration-free.
Fundex piles are full displacement bored piles, or FDP, as per DIN EN 12699. This pile system is especially suitable for use in inner-city locations. The low-noise insertion method used for these piles means residents will not be disturbed by any unnecessary construction noise. As the fabrication process is also vibration-free, Fundex piles can be used near fragile buildings.
Comparison between Atlas and Fundex piles.
A thick-walled steel pipe, sealed with a spiral-shaped, waterproof toe, is pressed into the ground by a rotary drive system. The tip displaces soil to each side, compacting the soil area around the pile.
The hydraulic driving pressure required during insertion is measured and compared with soil exploration data from drill profiles and sounding diagrams. Once the desired depth is reached, a reinforcement cage is inserted.
The pipe is then filled with concrete and the drill pipe is rotated to right and left to allow concrete to penetrate below the pipe. This process produces the smooth shaft of the Fundex pile. The toe remains in the ground as a pile foot.
Full soil displacement means this pile system is also suitable for use on contaminated sites. To reduce the carryover of contaminated soil during pile fabrication, we use a 60-degree pile toe when drilling through the contaminated layer. Alternatively, it is also possible to work with a lead seal fitted, to prevent the pollutant from travelling into deeper layers.
The short preparation period, speed of pile fabrication and high load-bearing capacity of the Fundex piles ensure high economic viability and shorter construction periods. The insertion process and constant monitoring of the necessary resistance mean the pile length can be ideally adapted to the various soil layers.
