Driven pile FORATEP

steelfoundation

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. Construction sequence 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 Fields of application • 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 Environmental impact • Vibration-free • Absence of noise pollution • Provision should be made to handle the drilling fluid Technical specifications • 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
