Crushing & Hammering
Turn blasted ledge, concrete, and rubble into usable fill — right on your site. One machine. No haul-off. No buying aggregate.
Left: Hardox crusher bucket processing blasted ledge into 3″ minus fill. Right: JSB2200 hydraulic breaker (140mm chisel) breaking ledge without blasting.
Process rock straight from the dig
The crusher bucket is a jaw-crusher that hangs right off the excavator arm. We scoop blasted ledge, fieldstone, old concrete, or demolition rubble — and crush it to reusable aggregate in a single pass. No separate crusher plant, no haul-off trucks, no buying aggregate to bring back in.
Output is typically 3″ minus — right-sized for structural fill, driveway base, trench backfill, and wall backfill. If the rock is coming out of your site, we make it work for your site.
- Crushes blasted ledge, boulders, fieldstone & demolition concrete
- Output 3″ minus — ready for structural fill or base course
- Works in confined excavations and tight-access sites
- Eliminates haul-off cost and fill purchase on many jobs
- Hardox wear-steel liner built for abrasive NH ledge
JSB2200 hydraulic breaker (140mm chisel) on the MisterDig CAT 320 — no blast permit, no drill crew needed.
Break rock without blasting
The JSB2200 hydraulic breaker delivers heavy, focused impacts through a 140mm chisel — mounted directly on our CAT 320. When a controlled blast isn't the right call — too close to a structure, permit timeline too long, rock pocket too small — the hammer gets it done from the same machine already on-site.
No blast permit. No exclusion zones that shut your site down for a day. We break the rock in the cut, excavate it, then run it through the crusher bucket — often in the same shift.
- No blasting permit — faster scheduling, no inspector delays
- Less vibration than drill-and-blast near structures
- Effective on ledge outcrops, boulders & frost-heaved slabs
- Works within tight setbacks to foundations & utilities
- Pairs directly with crusher bucket: hammer, then crush
Best use cases
- Post-blast cleanup — process the pile, skip the trucks
- Demo concrete turned into driveway base
- Remote sites where aggregate delivery is costly
- Foundation & retaining wall backfill from excavation spoils
Best use cases
- Ledge within close setback of a structure or utility
- Small rock pockets — not worth drill-and-blast economics
- Jobs where blast permits would cause weeks of delay
- Rock seams interrupting a trench, footing, or utility dig
Hammer + Crush in one mobilization
Break with the hammer, excavate the loose rock, feed it into the crusher bucket, place the processed fill. Tight loop — no trucks, no waiting, no second trip. We price it as a package when it fits your scope.
Post-blast pile processing
A controlled blast breaks the ledge — but you still have a pile of rock to deal with. We can add the crusher bucket to the same blasting scope: blast, crush, reuse. Ask us to price it as a package on your ledge removal estimate.
