Guide — Retaining Wall Estimator
The retaining wall calculator below follows standard Indian construction practice and the relevant IS-code conventions. Enter the site dimensions exactly as measured, press Calculate Now, then refine the quantities line by line in the live sheet before you export.
A cantilever retaining wall is proportioned before it is analysed: base width 0.5–0.7 times the retained height, base thickness roughly H/12, stem thickness H/12 at the base tapering to 200–250 mm at the top.
Rankine active pressure uses Ka = tan²(45 − φ/2). For a granular backfill at φ = 30° this gives Ka = 0.333, and the resultant thrust acts at one-third of the height above the base.
Drainage decides whether the wall survives. Weep holes at 1.5–2 m centres, a granular filter behind the stem and a perforated drain at the heel prevent hydrostatic pressure, which can double the design thrust.
Treat every output as an indicative pre-tender estimate. Site conditions, wastage allowances, specification changes and local market rates all move the final figure, so validate against your drawings and approved rate analysis before procurement.

About the Retaining Wall Estimator
This tool is built for site engineers, quantity surveyors, contractors and property investors who need dependable numbers fast. Every input is reactive — changing a single field instantly recomputes the full output set, so you can run sensitivity checks on dimensions, grades and rates before committing to an estimate.
Keep unit consistency in mind: metric inputs (metres, square metres, cubic metres) produce metric outputs, with imperial and Indian trade units shown alongside where they are commonly used on site.
