Frequently Asked Questions

Can the MiniTrencher SB216 bore underneath concrete sidewalks?

Yes. The SB216 is designed to create horizontal holes through suitable soil beneath sidewalks without removing the concrete above.

Does the SiBore require water?

No. The SB216 uses a mechanical boring system that operates without water, reducing muddy conditions and cleanup.

How far can the SB216 drill?

The included kit contains three 32-inch extension rods. Actual boring distance depends on the auger configuration, soil conditions, and available extensions. Consult the manufacturer for longer boring applications.

Can it drill through rocks or concrete?

No. The SB216 is designed primarily for suitable soil conditions. Large rocks, roots, buried obstructions, and solid concrete may prevent successful drilling.

Can the SB216 be used with a GeoRipper trencher?

Yes. The SiBore complements GeoRipper trenchers by creating underground passages beneath sidewalks where open trenching is not practical.

What should I check before drilling?

Always locate underground utilities before boring and verify that the proposed path, depth, and soil conditions are suitable. Follow all applicable utility-location and jobsite safety requirements.
