Ownership and publishing responsibility
Retaining Wall Calc is owned and operated by Ejaz Elahi, a mechanical engineering graduate based in Pakistan.
Retaining Wall Calc is the publishing brand responsible for the calculators, guides and explanatory illustrations on retainingwallcalc.org. Page bylines link to the brand’s About page. This is an independent material-planning resource, not a licensed structural engineering practice or a manufacturer’s design service.
AI-assisted drafting and development are used. Ejaz Elahi is responsible for the published material, and page bylines identify Retaining Wall Calc as the publishing brand. His background and role are described on the About page. We do not publish invented author biographies, qualifications, endorsements or project experience.
Ejaz Elahi, BS Mechanical Engineering, is the owner and named technical reviewer.
What has been checked
The model is documented on the methodology page. Checks cover course and unit rounding, buried rows, unit conversions, caps, stone volumes, curved and stepped runs, masonry mortar modules, timber counts, allowances and entered-price totals. Worked examples are compared with independently calculated expected quantities.
These checks assess arithmetic and displayed assumptions. They do not test a proposed wall’s resistance to sliding, overturning, bearing failure or global instability. They cannot establish foundation adequacy, drainage performance, reinforcement requirements or permission to build.
Technical review scope and current status
The owner review covers the calculator formulas, worked quantity examples, unit conversions, course and order rounding, allowances, and the accuracy of the stated estimating assumptions and source descriptions. It does not approve a retaining wall design, determine geogrid requirements or certify compliance with local rules.
No named independent engineering reviewer is currently credited. An owner review is an internal review. An independent-review credit requires an actual review by a separate reviewer, with relevant qualifications, scope and completion date.
Site-specific soil, loading, water, frost, boundary and local approval questions need an appropriately qualified local professional. A successful calculator or structured-data test is not an engineering certification.
Sources, prices and illustrations
Product dimensions, packaging and installation context use identified manufacturer or supplier references. Approval examples use the named authority’s guidance. One council’s rule, a product-specific height limit or a dated supplier price is not a universal requirement or market average.
Source-check dates and example limits appear on relevant pages. Illustrative prices are distinguished from dated public prices and quotes entered by readers. Verify the current local product, package and delivered price before ordering; sources can change after they are checked.
Our quantity diagrams are explanatory schematics, not photographs of completed customer projects. We do not invent customer ratings, reviews, case studies or manufacturer affiliations. Any future project photograph or third-party review needs a verified source, permission for use and an accurate description.
Corrections and material updates
Use the contact form to report a formula error, unclear label, outdated reference or misleading example. Include the page, measurements, units, observed result and the expected result or source. Do not include private customer information or sensitive construction documents.
Corrections are assessed against the model, worked examples and relevant source. Changes affecting calculations or material explanations are checked before publication. Substantive content changes receive an updated date while original publication dates are retained. External source changes and project-specific disagreements may need further verification.
Editorial independence and funding
A commercial relationship does not establish a product’s suitability or approve a wall design. Paid placements and affiliate relationships, if introduced, must be identified where readers encounter them. Editorial examples remain subject to the same source, arithmetic and scope checks.
The commercial disclosure explains the current status and standards for future paid content.
