Loading Dock Drain Installation, Repair, and Cleaning
HT Strenger installs, repairs, and cleans the trench drains, dock pit drains, and dock sump pumps that keep loading docks working through Chicago-area winters. Warehouses, distribution centers, food service facilities, retail back-of-house docks, and manufacturing loading bays across Lake County rely on these systems to move snow-melt, rain runoff, and wash-down water away from the dock plate and out of the tenant space. When they clog or freeze, docks flood and freight sits.
A dock that drained fine when the building was new is often at 30 percent capacity ten years in. We inspect, camera the run, and identify the actual restriction instead of guessing.

Why Dock Drains Fail
Loading dock drains are one of the toughest environments in the building.
- Salt, sand, and grit ride in on trailer tires all winter and pack the drain body.
- Snow and slush dumped off truck roofs and forklifts overwhelm undersized drains.
- Sub-freezing air chills the pipe from the top down, and standing water in a trap freezes solid until spring.
- Diesel, hydraulic fluid, and food-service wash-down leave residues that build up on drain walls and check valves.
- Pallet drops and impact loading crack grates, warp frames, and shift trench sections out of alignment.
Trench Drains, Point Drains, and Dock Pit Sumps
Different dock configurations need different drainage.
- Trench drains run parallel to the dock face and catch runoff across the whole approach. We install and repair pre-cast and cast-in-place trench systems with heavy-duty ductile iron grates rated for forklift and truck loads.
- Point drains work in smaller docks and interior wash-down areas where a single low point does the job.
- Dock pit sump pumps move water out of a dock leveler pit that sits below the surrounding grade. These are simplex or duplex packages with float switches and high-water alarms. They belong in every below-grade dock pit in a Chicago-winter climate.
Pro Tip: Insulate the discharge line from a dock sump pump where it exits the building, and keep at least one heat-tape circuit on the outdoor run through a freeze. A frozen discharge line burns pump seals and floods the pit within an hour. It is a $100 fix in December and a $2,000 problem in January.
Cleaning, Jetting, and Repair
Most dock drain problems are cleaning problems. We high-pressure jet the drain body, the trench, and the discharge lateral, camera the run to confirm the restriction is gone, and pull broken grates or repair heaving trench sections while we are there. When the drain body itself has failed (cracked concrete, rusted-through steel), we cut it out and replace with a modern polymer trench section rated for the truck loads.
