A single soil cell system can hold enough quality soil to support a tree for its entire lifespan, helping urban trees grow up to four times larger than those planted in traditional sidewalk pits.

At Twin-City Interloc, we use soil cell technology to give urban trees the best chance to thrive. Unlike traditional sidewalk tree pits, soil cells provide the space and nutrients trees need to grow strong and healthy—while also managing stormwater beneath the surface. The result is greener streetscapes, reduced flooding, and longer-lasting infrastructure with less maintenance. By choosing soil cells, you’re not just planting trees—you’re investing in a healthier, more sustainable community.
