Every part, in place.
Drag to orbit the actual model. One precast node, four cast-in sleeves set at 26°, four helical nails driven — not poured — into bearing soil.

Each nail is a hardened steel core with a galvanised coating rated for long-term soil exposure, and a helical thread that locks into strata rather than compressing it.
Bearing capacity vs. conventional footing
Force disperses down four opposed angles instead of one vertical mass — the same principle as a tent stake set against the wind, at structural scale.
Conventional excavate, form, pour, cure
PEN — set, drive, done
Reads the ground it's driven into.
Each nail locks into the densest strata it reaches — the section below shows exactly where that grip happens for a given soil profile.
Tested against vertical, lateral, and seismic load.

Directional estimate from published PEN assumptions (~2 h/point, 6× faster deployment, ~100 kg CO₂-eq avoided per unit). Actual figures depend on site conditions.
