Commercial Drain Tile Systems

Engineered subsurface drainage to protect commercial buildings, parking lots, and pavement from groundwater damage.

Groundwater is one of the most persistent threats to commercial properties—damaging pavement, weakening foundations, and creating frost heave in our Minnesota freeze/thaw cycles. At Diversified Drainage, we design and install engineered drain tile systems that intercept subsurface water and redirect it away from vulnerable structures.Unlike surface solutions, commercial drain tile works underground, capturing water before it causes damage. We tailor every system to site-specific soil conditions, building layout, and drainage goals to ensure performance and code compliance. Whether you're developing a new site or solving issues at an existing facility, our drain tile solutions provide long-term protection you can count on.

Commercial Drainage FAQs

Proper groundwater management starts with the right system—and a clear understanding of how it works. Explore these FAQs to learn more about commercial drain tile.

What is the building code for drain tile in Minnesota?

Minnesota building code requires foundation drainage systems—such as drain tile—for commercial structures when water tables or soil conditions warrant it. All systems must meet code requirements for pipe materials, slope, outlet locations, and connection to approved drainage or sump systems. At Diversified Drainage, we design every system to exceed code and ensure long-term performance.

How deep should commercial drain tile be buried?

Most commercial drain tile systems in Minnesota are installed 24 to 48 inches deep, depending on frost line, footing depth, and soil conditions. Proper slope and backfill material are critical for long-term functionality, and depth must allow for gravity flow or tie-in to sump systems.

Is drain tile worth it for commercial properties?

Absolutely. Drain tile prevents water damage, frost heave, and soil instability—common causes of slab cracking, pavement sinking, and mold issues. For commercial sites, it’s not just worth it—it’s often essential to protect your investment and meet drainage regulations.

Who installs commercial drain tile systems?

Only qualified drainage contractors or civil sitework professionals should install commercial drain tile. Diversified Drainage specializes in engineered drainage systems for Minnesota’s toughest sites, ensuring each installation is tailored, compliant, and built to last.
