04 / QUESTIONS

Good questions.
Clear answers.

A better estimate starts with knowing what it does and doesn't include.

How do I calculate blocks for a curved retaining wall?

Choose an inside or outside curve, enter the radius and angle, select your block profile, and specify courses. The estimator adjusts the front-face radius by course and calculates nominal block placements using the block's face width. Add your own waste allowance for the shopping estimate.

What's the difference between an inside and outside curve?

The front-face radius changes in opposite directions as a wall rises because of block setback. An outside (convex) curve usually gets tighter toward the top; an inside (concave) curve usually grows wider. Measuring from the top or base course changes the starting radius calculation.

Are cap quantities and cutting instructions exact?

Cap quantity here is based on your entered coverage per piece and the top-course run. Actual caps, miters, waste, and final cuts depend on the manufacturer's specific cap product and your site. The CurveSet mobile app provides more detailed geometric plans to field-check. Android is currently in internal testing; iOS is planned.

Can I use my own block dimensions?

Yes. Choose “Custom block size” and enter front-face width, height, and setback. Catalog dimensions are nominal, and regional products can differ; verify dimensions with your supplier.

Is this a structural retaining wall design?

No. This is a geometry and materials-planning tool, not a soil-stability, drainage, surcharge, geogrid, or code-compliance design. Follow the current product installation guide and use a qualified engineer when site conditions or local requirements call for one.

Is the calculator free?

Yes. The web calculator runs locally in your browser with no account, backend, or payment. CurveSet's mobile app includes a free tier, with additional project and worksheet functionality offered through a one-time Pro purchase.
