PileCalc vs CivilTech AllPile

Everything AllPile does — in a 2026 interface, for $39.99/month.

Lateral, axial, groups, drilled shafts and footings — AllPile's full breadth, validated against two independent codes (LPILE and RSPile), running in any browser with an explanation behind every input.

AllPile's all-in-one philosophy is exactly right, and it's the closest match to PileCalc's scope. PileCalc keeps that breadth but replaces the dated desktop UI with a modern, browser-native, fully explained workspace.

What CivilTech AllPile does well

  • Genuine breadth — lateral, axial, settlement, groups, shafts and footings in one tool
  • Inexpensive, perpetually licensed
  • Long-established on real projects

Where PileCalc is different

  • A 2026 interface instead of dated gray tabbed forms
  • Runs on macOS, Windows, Linux or a Chromebook — no install
  • Matches AllPile's extras too — downdrag, torsion, uplift and capacity-vs-length — and adds helical piles, buckling, foundation stiffness springs, rigid-cap 6-DOF distribution and structural cap checks
  • Validated against two independent codes (LPILE and RSPile), with numbers published
  • Shareable cloud projects, a REST/Excel API, and an explanation behind every input

The numbers, published

PileCalc's engine is checked term-by-term against the reference codes. A representative sample of the benchmarks — every intermediate value is visible in the app so you can reproduce them yourself.
