A rebar lattice is constructed underground and then coated and filled with either a high-strength gunite or a proprietary concrete mix that is pumped remotely or from the surface. The speed and ease of installation saves the mine time and money. Pumping the StrataCrete mix from the surface is cost-effective and provides the added benefit of eliminating huge quantities of materials handling underground.

The Reinforced StrataCrete Seal can be fully constructed in 4 to 6 shifts depending on mine dimensions.

Strata Mine Services offers turnkey installation of ventilation seals and overcasts to control mine ventilation and maintain safe working environments.
