M.C. Donegan performed drilling, blasting, and presplitting for a Federal Highway Administration flood recovery project. Stakeholders wanted presplit rock slopes with minimal half casts visible, for natural looking slopes. Production of riprap from blasting operations were used for river bank stabilization.

Slopes were designed on a ½ to 1, on 4’ to 5’ centers, with a 3.5” hole. Split factors ranged from .02 to .05 lbs/Sqft. The geology is primarily metamorphic rocks fairly weak in structure.
