CEMATRIX – What $1.5 Million Of Tunnel Grouting Looks Like

CVX:TSX-V

CEMATRIX and its specialized cellular concrete solutions have many infrastructure applications.

Over the coming months, we will highlight various applications, shed more light on its countless possibilities, and add some colour to how cellular concrete is used.

Completed Tunnel

Recently, CEMATRIX completed a project for a new Canadian client. The $1.5 million project was for tunnel grouting at a hydroelectric facility outside of Pemberton, British Columbia. This was originally scheduled for completion in 2016, however it was pushed forward into early this year due to a forest fire in the Pemberton area last fall which resulted in an evacuation of the site.

Cellular concrete is a superior solution for grouting a tunnel for a myriad of reasons. This project took three weeks for CEMATRIX to pour with one of its high volume dry mix units, whereas traditional grouting would have taken months to complete because it is pumped slowly into the tunnel under high pressure and does not flow well. Cellular concrete, on the other hand, is produced and placed under low pressure and flows like lava because it is largely made up of trillions of tiny cement coated air bubbles that act like frictionless ball bearings.

Pouring Cellular Concrete

The project took place in the worst winter conditions in February/March, proving CEMATRIX is capable of working in extreme conditions year round.

CEMATRIX has been growing this application across Canada and the United States and sees tunnel grouting as a large part of its expected growth for years to come.
