RockLok Airdeck
Airdecking plugs engineered for better energy distribution and stemming retention in the blast hole.
High-performance airdecking devices engineered to optimize detonation pressure, reduce explosive consumption (powder factor) by up to 25%, and prevent premature stemming ejection in open-pit mining benches, tunneling, and quarry excavations across Indonesia.
Calculated Explosive Confinement
Rigid lab benchmarks and real quarry blast trials demonstrate repeatable improvements in blasting physics and heave predictability.
Optimal Shockwave Reflection
Creates an engineered air cavity that forces repeated shockwave reflections against borehole rock faces before gas venting, intensifying micro-fractures.
Up to 25% PF Reduction
Replaces high-cost bulk emulsion or ANFO columns in dead zones without sacrificing fragmentation velocity or shovel digging ease.
Stemming Retention & Safety
The high-grip perimeter wedges firmly into rock strata, preventing the stemming aggregate from bridging or discharging into the open air as flyrock.
Vibration & PPV Damping
Dampens sudden peak explosive pressure curves, substantially lowering Peak Particle Velocity (PPV) and air-blast decibels near residential perimeter zones.
4-Stage Rapid Deployment Procedure
CYCLE TIME: ~15 SECONDS PER HOLE
Depth Sounding & Verification
Verify total hole depth and water table presence using a calibrated weighted tape to confirm pre-calculated air deck placement benchmarks.
RockLok Tethered Lowering
Fasten the tag line to the ergonomic top loop of the RockLok unit and smoothly lower down the blast hole axis to the designated deck elevation.
Mechanical Self-Locking
Slight tug on tag line activates high-friction flexible outer fins, jamming securely against rock borehole contours to create an immediate gas seal.
Explosive / Stemming Loading
Immediately backfill crushed aggregate stemming or upper emulsion deck. Zero curing wait, allowing the loading truck to maintain rhythm without stops.
