If the rock contains an excess of fines or inadequate voids, the desired results may be impossible to obtain. When slope protection is paid by volume, review the plans and quantity calculations in the resident engineers file to determine if there is sufficient detail and accuracy to be used in the project records. If there are no prevailing agency specifications, it is recommended to follow AASHTO M288 for subsurface drainage applications. To respond to the different problems associated with instability of rock faces, Geofabrics also has a broad range of independently verified rockfall mitigation systems.
