TekStem was developed in response to the need from the seismic surveying industry for a superior stemming material.
Minova proprietary HYG technology is incorporated in the formulation. By combining with a large quantity of water this permits just one 50 lb bag of TekStem to fill 40 ft of 3-1/2” diameter borehole or 24 ft of 4-1/2” diameter borehole.
Very high success rate
Very high success rate in “difficult” ground compared to other stemming techniques
