Frequently Asked Questions: Commercial Overhead Dock Doors, Dock Seals & Building Envelope Waterproofing in Duluth, MN

How much heat is our Duluth warehouse losing through worn-out loading dock seals and uninsulated doors?

A single 8'x9' loading dock in Clough / Rice's Point Port of Duluth Industrial & Maritime Terminal District, Airpark Industrial Park (Cirrus Aircraft / Duluth International Airport Hub), Miller Hill Commercial Corridor, Essentia Health & St. Luke's Medical District, Canal Park & Downtown Waterfront with torn dock pads and missing leveler brush seals leaks the equivalent of a 2-foot-square hole in the wall 24/7—costing $2,500 to $4,200 per door every Minnesota winter in wasted natural gas.

Should we install compression foam dock seals or rigid/flexible dock shelters on our Duluth facility?

Standard 8'x8' or 8'x9' doors serving uniform 53-foot dry vans in Duluth achieve the tightest thermal seal with compression foam pads; larger 10'x10' doors or facilities receiving varied trailer heights with liftgates require wipe-style dock shelters.

Why is water leaking into our underground parking garage or basement mechanical room in Duluth?

De-icing salts tracked onto plaza decks and parking ramps in St. Louis County corrode reinforcing steel and split concrete expansion joints. We rout and seal dynamic joints and apply multi-layer elastomeric traffic coatings.

Can you replace smashed loading dock bumpers, bent door tracks, and crumbling dock concrete in Duluth?

Yes. Our commercial exterior crews rebuild spalled concrete dock edges, weld structural steel channel angles, anchor laminated dock bumpers, and install concrete-filled steel pipe bollards.
