A rise of 0.5m over a 20m run:
Use this when checking drainage slopes, setting grades, verifying drawing specifications, or converting between the different ways slope is expressed across various drawings and standards.
This does not replace a survey or formal grading plan. For final grade certification, use surveyed elevations and proper engineering review.
Typically 0.5-1% minimum for positive drainage on paved surfaces, though this varies by local standards and the type of surface.
It means for every 40 units of horizontal distance (run), there is 1 unit of vertical rise. This equals a 2.5% slope.
Depends entirely on soil type. Common earth is often cut at 1:1 (45°), while rock can be much steeper. Always follow a geotechnical recommendation for cut slopes.
