A FORATEP pile (Tube Enfoncé par FORAge) is a pile formed by grout injection under pressure in a borehole under the support of water or another support fluid. The Foratep pile is installed with small drilling equipment, in confined and narrow working areas.
1. & 2. Rotary drilling of tubed elements using a drilling fluid
The inner steel tube segment is sealed by a lost closing nut tip.
3. At the required installation depth, replacement of the drilling fluid by a cement grout
4. The completed FORATEP pile
• Pile foundation withstanding reduced loads, suitable in confined spaces or in areas with limited headroom and / of restricted access
• Underpinning of existing buildings and stabilization
• Vibration-free
• Absence of noise pollution
• Provision should be made to handle the drilling fluid
• Length of tube segments variable, but mostly 1 m long
• Injection hole at the bottom of the tube
• Allowable bearing capacity up to maximum 120 kN
• Possibility to resist tensile loads
• Use of self-drilling hollow bars
