Our process

How We Make Sure the Numbers Are Right

1

Build and test

Muzammil codes each feature and tests it against worked examples, such as 24 x 14 ft at 6 inches giving 6.22 cubic yards.

2

Expert review

Abrar checks the formulas, gravel weights, depth guides and driveway layers against how the work is done on real landscaping jobs. Weights are based on published US supplier and quarry data.

3

Keep it current

When a reader reports a problem or a supplier figure changes, we check it, fix it and update the review date.
