Stable Air™ is an additive we use to produce extremely light and versatile concrete or grout. In this technology – known as “cellular” – fine air bubbles are incorporated into the concrete or grout. These millions of small air bubbles are spread uniformly throughout the mixture to form an extremely stable network. This produces a more fluid product appropriate for many different uses.
The Stable Air™ additive ensures the concrete’s volumetric stability. This is what allows for its various uses. This cellular technology allows us to create custom mixes to meet specific needs. Stable Air™ is an innovative solution to several common on-site technical challenges.
Lightweight and fluid, Stable Air™ concretes and insertion grouts are perfect to fill a variety of cavities. This is also the case for unreachable places, because these mixtures are placed over long distances and level themselves without outside intervention. They can also be used to stabilize the ground, reinforce existing foundations or pour a soundproof floor in a wood-frame building.
At Béton Provincial, we’ve used the cellular technology to solve a variety of technical problems. To date, over 10,000 m³ of Stable Air™ have been used by Béton Provincial on various sites, including the Turcot Interchange, the REM project and several other MTQ projects as well as the City of Montreal. Using the tunnel lining technique, our team executed in a remarkable way the filling of the space between new and old underground pipes. Finally, Stable Air™ is not only designed for light filling and pipe insertion: several other applications have shown the versatility and great potential of this technology.
