FREE FIELD TOOL
CALCULATE PIPE SLOPE AND INVERT ELEVATIONS
Use the OLH Pipe Slope & Invert Calculator to calculate pipe slope, elevation change, and upstream or downstream invert elevations from the information you have in the field.
Check the math before installation so the pipe stays on grade and the elevations work from structure to structure.
USE IT FOR QUICK PIPE GRADE CHECKS
- Choose the calculation you need.
- Enter the known invert elevations, distance, slope, or fall required by that calculation.
- Use Find Ending Invert to calculate where the pipe should finish.
- Use Find Slope or Find Fall to check the grade between two elevations.
- Use Check Intermediate Invert to verify grade at a point along the run.
- Review the result before carrying the number farther down the trench.
Note: This tool supports field calculations and checks. Always verify plans, survey control, structure elevations, flow direction, tie-in conditions, and project requirements before relying on a calculated invert.
