A free WALLAP alternative in your browser
WALLAP is commercial software for the analysis of embedded retaining walls such as sheet piles and contiguous or secant pile walls. If you need to do similar work without an installation or a licence — for preliminary design, checking, teaching or a quick answer on site — the CivilWorks Atelier studios below cover the same kinds of tasks for free, with step-by-step calculation sheets, drawings and Excel.

- Free and instant — no installation, licence server or sign-up; it runs on a laptop, tablet or phone.
- Every step shown — calculation sheets (PDF) with the formulas, values and code clauses, ready to check by hand.
- Drawings and data — A3 drawing sets, SVG and PNG figures, Excel workbooks and JSON project files.

Where WALLAP still fits
Large three-dimensional models, project-wide data management and analyses that need a validated commercial program and its support remain the job of tools such as WALLAP. CivilWorks Atelier is best used for preliminary design, independent checks of a model, quick site answers, teaching and small projects.

Questions
Is CivilWorks Atelier a free alternative to WALLAP?
For many everyday tasks, yes: the analysis of embedded retaining walls such as sheet piles and contiguous or secant pile walls can be worked through in the free browser studios listed on this page, with calculation sheets and drawings. It is not a copy of WALLAP, does not open its files and is not affiliated with its developer.
Can I use the results for design?
The studios follow published design standards and show every step, so each result can be checked by hand. They are intended for preliminary design, independent checking and learning; final designs should be verified by a qualified engineer.
Do I need to install anything or pay for a licence?
No. Everything runs in a web browser on a desktop, tablet or phone, and the studios are free to use. Your inputs stay in your browser.
