The Stemlock Gas Bag is a self inflating borehole plug that is used to block or seal a hole at any depth.
They are made for 3" to 16" diameter holes. There is no need for an air compressor, for the bags self inflate chemically. There is no leakage because the Gas Bag is sealed during the manufacturing process.
There is no heat produced during inflation and the ingredients are not carcinogenic.
Substantial savings of up to 35% in explosives costs can be made by using the Gas Bag for air column blasting techniques.
