Prefabricated vertical drains
PVD consolidation analysis for professional engineers
Design, simulate and back-analyse ground improved with vertical drains, from first-pass spacing to calibrated settlement forecasts.
Three tasks, one soil model
Design
Find the drain spacing that reaches your target degree of consolidation by a given time, deterministically or as a P10 / P50 / P90 band.
Simulate
Predict consolidation and settlement over time for a chosen spacing, including smear, staged loading and vacuum preloading.
Back-calculation & forecast
Calibrate soil parameters against settlement plates and piezometers, then forecast the rest of the settlement record.

Calculations run server-side. Nothing proprietary is shipped to the browser.
Private by design
Every project is visible only to the account that created it, enforced in the database itself.
