Trenching with Royex

Trenches are generally built for pipelines of oil, water, sewage, and cables. The nature of these installations and services often entails working in densely populated areas. The use of low energy Royex propellant charges minimizes the risk of ground vibration, fly rock, dust and noise. 

Further, deep trenches almost always requires good wall integrity making wall and over break control essential to avoid trench collapse. Using larger diameter Royex cartridges in center holes and smaller perimeter cartridges in the outer wall holes allows for a minimal wall damage. 

The video to the right illustrates the result of a large trench developed with Royex.  As can be seen the operation was done in a highly urban area just centimeters from a brick house.
