What is bio-inspiration?
Fibrous plant roots are highly efficient at resisting pullout loads. That is, they're very difficult to pull out relative to their mass. Root-Inspired Ground Anchors apply the same principles to full-scale geotechnical tiebacks and ground anchors.
Half-scale field trials show RIGA's potential to out-perform conventional grouted anchors (Huntoon et. al, 2022).
Conventional drilling techniques and construction materials create a bio-mimetic ground anchor with enhanced pullout efficiency.Â

Installation follows four simple steps:
1. Drill Sub-Horizontal Hole
2. Place Root-Inspired Ground Anchor
3. Grout & Actuate
4. Remove Installation Equipment
Actuation produces instant feedback on soil conditions in the anchor vicinity.
Additional design redundancy is available through post-grouting.
GetRIGA, BioBilt's performance prediction software, enables reliability-based design processes for Root-Inspired Ground Anchors.
