About Retaining Wall Calc
Free retaining wall material estimates with transparent formulas
Retaining Wall Calc is a free web resource for planning retaining-wall material quantities. It helps homeowners, landscapers and suppliers prepare a starting material list using their actual wall dimensions, product sizes and supplier prices. The calculators keep exposed and buried courses, separate caps, base aggregate, drainage stone, pipe and fabric visible. They support imperial and metric measurements, editable allowances and density, entered-price budgets and printable results. Worked examples and published formulas explain how the counts are produced. This is a showcase of an actively maintained project. The website is not offered for sale. It estimates quantities and entered costs; it does not check wall stability, choose structural reinforcement or foundations, or approve construction. Confirm final products, quantities and design details with the supplier and appropriate qualified professional.
