(Cellular Flowable Material for Annulus and Cavity Fill)
When underground pipelines, tunnels, or utility casings are no longer in use, it’s essential to fill those voids properly to prevent ground settlement, surface collapse, or future liabilities. Lightweight cellular concrete (LCC) is an ideal solution for pipeline abandonment and annular grouting, offering excellent flowability, low density, and reliable long-term stability.
Because of its pumpable nature and ability to flow over long distances, LCC can be placed in inaccessible or deep areas without the need for heavy excavation. It’s ideal for filling abandoned sanitary and storm sewers, water mains, gas pipelines, and conduits—especially when structural integrity and lightweight load are key factors. The material’s cellular structure allows it to displace water, conform to irregular shapes, and set without shrinkage or compaction.
Elastizell of Wisconsin brings decades of experience to pipeline abandonment and void-fill projects across the state. Our in-house crews and specialized mobile batching equipment allow us to mix and place cellular concrete on-site, ensuring material consistency and minimizing job site disruption. As a trusted union contractor affiliated with LiUNA Local 113 and OPCMIA Local 599, we adhere to strict safety and quality standards on every project.
We understand that these types of projects often come with logistical challenges, tight timelines, and sensitive environmental considerations. That’s why we work directly with contractors, engineers, and municipalities to tailor the mix design and placement strategy to the site’s exact needs.
