Industry Facts

Compare the Real Cost of Rock Blasting or Hammering & Excavating to the Proven Technology of Trenching.

Trying to trench through solid rock, substantial surface, or subsurface pavement can be a nightmare. Blasting and hammering are slow, unpredictable and ultimately, expensive. Plus blasting significantly increases your risk of liability. Choosing a trencher designed for rock is the key.

There is a better way. Let's compare:

Rock Trenching:

	1. A rock trencher cuts through several layers of pavement and soil while excavating the spoil from the cut...all performed in a single pass.
	2. Trenches have consistent dimensions, so surrounding structure is undisturbed. Trench walls are vertical, minimizing excavation. The flat-bottom trench is straight and at a controlled grade.
	3. Backfilling and finishing are minimized. Soil from the trencher is often useable as backfill material. Uniform trench walls aid compaction. The minimal opening at the top of the trench conserve patching materials.

Blasting/Hammering & Excavating:

	4. Blast forces and hammering & excavating forces fracture and disturb surrounding structures that can increase liability and risk.
	5. Irregular sloped trench walls are produced, requiring greater excavation effort. Surrounding rock is often uplifted from blast and excavator.
	6. New backfill material is usually needed. The irregular trench walls resist compaction. Surface patching costs more due to wider opening and irregular trench edges. As surrounding structure settles, surface sinking may occur.
