Air-operated efficiency
Dual bladder security
Robust outer cover
Snap coupling ease
Enhanced fragmentation
Eco-friendly product
BLASTBAG™ AERO is an air-operated blastbag used to block, deck, or support explosives in blastholes. It’s designed for sites that run service air and need a clean, simple way to control voids and explosive energy. The AERO uses compressed air only, making it safe, reliable, and easy to run underground.
The dual bladder setup and the tough outer bag stop leaks and hold pressure well . The snap-on valve connects fast to standard underground air fittings. Once inflated, BLASTBAG™ AERO holds position, protects the drilled hole, caps upholes, and helps improve fragmentation. It also helps cut explosive wastage and control final wall conditions.
MTi also supplies hose reels, inflators, AB-C couplings, weights, and droplines to install the BLASTBAG™ in any direction — even underwater.

Air Decking with BLASTBAG™ AERO
Air decking creates a gap of air between explosive charges or explosives and stemming in the borehole. It can reduce vibration and gives you more control of energy distribution. BLASTBAG™ AERO excels at this.
The air deck/gap allows explosive gases to expand into that zone and fracture the rock. You can load a second charge or stem directly on the BLASTBAG™ AERO without concern of collapse or slumping. It will support your decks consistently from shot to shot.
Use air decking when you need:
- Reduced vibration in sensitive areas
- Improved pre-split and wall control
- Controlled fragmentation
- Reduced flyrock
- Reduced explosive cost

Frequently Asked Questions
FAQ's - BLASTBAG™ AERO
Where is BLASTBAG™ AERO used?
It is used in both underground and open pit operations. It works in upholes, downholes, and underwater situations where service air is available. It will stay in place even in wet, fractured, or inconsistent ground. With the weighted coupling, the BLASTBAG™ AERO can be lowered through water, then inflated at designed depth. BLASTBAG™ AERO is inflated with an external air source, giving you the option to lower it to depth, and then inflate it. Other plugs are typically initiated at the collar, making it more difficult to lower them very deep into the the borehole.
How does the valve connect?
The AERO uses a snap-on annular coupling that connects directly to standard mine air fittings.
Can the blastbag leak?
No. It uses a dual-bladder construction with a tough outer bag to prevent leakage
What pressure should the blastbag be inflated to?
BLASTBAG™ AERO should typically be inflated between 10-20 PSI.
It should not be inflated to pressures above 20 PSI (76-203 mm) or 10 PSI (230-350 mm). If high depth underwater decking is required, MTi Group should be contacted.
Can BLASTBAG™ AERO be used underwater?
Yes. It can be installed in underwater holes with the right accessories. It stays in place even in wet, fractured, or inconsistent ground. With the weighted coupling, the BLASTBAG™ AERO can be lowered through water, then inflated at designed depth.
Does the AERO allow charge-thru?
Yes. It can cap upholes and allow charging straight through the BLASTBAG™.
Is this the same as a stemming plug?
No. A BLASTBAG™ is an air-operated decking bag, not a mechanical stemming plug. It’s used to hold, separate, or support explosives. It can also be used, however, to support stemming. It can hold substantially more weight/pressure than a stemming plug.
What accessories does it work with?
Hose reels, handheld inflators, AB-C couplings, and droplines — all designed for both open pit and underground installation.

What is Air Decking in Blasting?
Air decking can let you use less explosive while improving fragmentation, reducing flyrock, and controlling vibration. Here's how it works — and why more sites are making the switch.
