Precast Aeration Tunnel Saves Time, Labor

Hanson Silo Company has been making precast bunker silos since 1916.

In spring 2019, the company introduced a precast concrete aeration tunnel to save time and labor at construction sites for flat storage grain buildings.

"The alternative to a precast concrete aeration tunnel is a cast-in-place concrete air tunnel, which requires thousands of feet of forming by hand," says Director of Business Development Mike Hanson. "It also takes up weeks of valuable site time. With our precast concrete aeration tunnel, all the lead time can be used in our yard, and the aeration tunnel can be set up in a day of site time."

Arduous Task Eliminated

"Creating a cast-in-place air tunnel is one of the most arduous tasks in constructing a flat storage grain building. Or precast concrete aeration tunnel saves customers time and labor," he adds.
