Cargo Port Drainage

Drainage Solutions

Truck terminals and shipping ports see significant tractor trailer and forklift traffic which means trench drain systems in terminals need to be HS20 or HS25 load rated and wide enough to capture large water flow from concrete lot.

Terminal buildings, where fork truck traffic with concentrated wheel loads are high, have lower drainage requirements. For this application, 4″ wide drainage systems with cast iron grates and frames are commonly used.

3 Considerations

Heavy Equipment

The constant traffic of forklifts, trucks and other heavy equipment requires trench systems to have Class E or Class F grates to hold up to the weight.

The Bigger They Are

Trucking terminals positioned at a low point of a large surface area require larger trench drain systems to handle the flow capacity. Interiors and warehouse buildings don’t require as much coverage and can get away with narrower drains.

Proper Planning

Trench drains designed for simple, straight runs don’t adapt to T intersections or angles.  For complex layouts, trench former systems and frame-and-grate systems will save time and money by eliminating on-site fabrications.
