The calculators and guides on Hardscape Estimator are for general information and planning only. They are estimates, not professional engineering, construction or contractor advice, and they are not a quote or a guarantee of the quantity you will need.
Estimates and material quantities
Results depend on the measurements and assumptions you enter, and on real-world conditions we cannot see: ground and base preparation, compaction, cuts and breakage, product sizes, moisture and how your supplier measures and sells material. Hardscape Estimator is not responsible for material shortfalls, overages, extra deliveries or other costs that result from relying on an estimate.
Verify before you build or buy
Always confirm quantities and specifications with your supplier. For structural work such as footings, retaining walls, driveways and drainage, hire a licensed contractor or engineer, and check your local building codes, permit rules and utility locating requirements before digging or building. Follow safety guidance for lifting, cutting, compacting and handling heavy materials, wet concrete and dust.
