GEWI^® Micropiles

The GEWI^® Pile design follows currently available methods for micropile, standard pile and earth anchors. As per FHWA-SA-97-070 Manual, minimum recommended design steps are:

• Review project information in regards to pile layout, loading requirements, access and overhead clearance
• Review geotechnical data for soil properties, design parameters, corrosion protection requirements, grout-to-ground parameters, bond length, pile spacing for group effects
• Structural design should include:
  • Anticipated settlement/required stiffness analysis
  • Lateral load pile capacity/ Anticipated lateral displacement
  • Buckling of the pile/soil lateral support
• Additional structural details such as: case and uncased length, strain/ductility of the steel, transition between case and uncased section, reinforcement splice connections, pile to footing connection, corrosion protection 
• Load testing program and quality control requirements
