Pile design software, in your browser.
Every deep-foundation analysis a project needs — laterally loaded piles by the p-y method, axial capacity and settlement, pile groups, drilled shafts, footings, uplift, moment–curvature and slope stabilization — in one web-based tool. No Windows, no dongle, no per-module licenses.
Lateral pile analysis
The FHWA COM624P p-y finite-difference method — the same approach as LPILE and RSPile, validated against both — with every curve exposed and every input explained. No install, no dongle.
Learn moreAxial capacity & settlement
NAVFAC DM-7.02 capacity — side friction, end bearing, limiting depth, downdrag, uplift — plus Vesić settlement and the full t-z / q-w load–settlement curve, in your browser.
Learn morePile groups
Vertical ultimate/block resistance, explicit ASD/LRFD design values and service-load sand settlement; lateral response with FHWA GEC 9 row p-multipliers.
Learn moreDrilled shafts
α-method clay, depth-dependent β sand, Horvath & Kenney rock sockets, belled-base uplift and exclusion zones — with the lateral p-y run of the same shaft one tab away.
Learn moreShallow footings
Shape, depth, inclination, slope and batter factors; biaxial eccentricity with full-contact checks; elastic settlement, base-friction sliding and rotation.
Learn moreUplift & anchors
Shallow and deep breakout in sand and clay, the transition handled explicitly, plus grouted-anchor adhesion — with every factor visible.
Learn moreMoment–curvature
Axial-equilibrated fiber M–φ for steel, reinforced/prestressed concrete, and composite sections — with explicit material models and direct nonlinear-EI coupling into the p-y solver.
Learn moreSlope stabilization piles
Wide-spacing pile-row demand/capacity across your supplied slip surfaces, with convergence checked on every solve — a pile-row analysis, not a global slope-stability solver.
Learn moreCapacity vs length
The NAVFAC DM-7.02 axial capacity swept over embedment length — side, tip, downward and uplift curves, plus the required length for your target load, without a dozen manual re-runs.
Learn moreTorsional load transfer
Separate shaft and toe ultimate resistance, then solve monotonic torque–rotation and depth transfer with explicit θ50 calibration and elastic GJ compatibility.
Learn moreDowndrag / negative skin friction
Impose the ground-settlement profile, and the analysis finds the neutral plane where pile and soil settle together — dragload, maximum axial force, and the full force and settlement profiles, per Fellenius and FHWA GEC-12.
Learn moreFoundation stiffness (springs)
A signed reciprocal lateral–rotation tangent matrix and both vertical secant and tangent stiffness at one explicit service state — with convergence, reciprocity and refinement evidence visible.
Learn morePile buckling
The first elastic buckling eigenvalue of a finite beam on explicit linear Winkler support — with partial embedment, variable EI, selectable head/tip restraint, and convergence evidence on every run.
Learn moreHelical piles
Individual-bearing and cylindrical-shear capacity computed and compared, per-helix bearing reported, and the AC358 torque correlation with your product's Kt — the full design loop in one tool.
Learn moreRigid and structural pile cap
Apply explicit factored load combinations, recover every pile-head demand with the Saul/CPGA rigid-cap method, then check the concrete cap for flexure, one-way shear, loaded-area punching, pile punching, and reinforcement adequacy.
