Enter your wall's length and height — get Boss Block counts, wall weight, and base & drainage material quantities. Drawing a layout with corners? Use the plan view. Terracing a slope? Use the slope tool. For stability checks run the full engineering tool.
Planning estimate only. Block counts and quantities for budgeting. Final wall design — especially over 4 ft exposed, with slopes, tiers, or loads above the wall — needs the engineering tool and review by a licensed engineer.

Embedment: bury at least 10% of wall height — 1 ft covers walls to about 7 ft. Boss Block: 30″ × 30″ × 60″ full units, 15″ caps, round tapered lug connection.
Base & Drainage Materials
Quantities match the engineering tool's defaults: 12″ free-draining rock zone behind the wall, 6″ crushed-rock leveling pad, 4″ perforated pipe at the heel. Compact the pad; daylight or tightline the pipe.
Baseline Guidance
These triggers come from the geotechnical models behind the engineering tool. When any apply, quick numbers aren’t enough — run the workup.
