20. Floor Drain
A fixture providing an opening through the floor to drain water into a plumbing system.
A description of liquid movement.
22. Frame and Grate
The combination of an attached metal frame and its supported trench drain grate. The frame provides a durable grate bearing surface and may also allow mechanical attachment of the grate.
23. French Drain
An underground passage for water or other liquids, consisting of loose stones covered with earth. Modern adaptations incorporate perforated pipe for storage and transmission.
Fiberglass reinforced plastic.
25. Galvanized Grate
A grate fabricated of pre-galvanized metal or hot dipped, after fabrication, with zinc to inhibit corrosion.
A chemical process where zinc is bonded to metal providing corrosion resistant protection and inhibiting steel from rusting. Galvanizing is a sacrificial layer having an effective life dependent on its environment.
27. Grate Frame
The frame component of a drain frame and grate. Grate frames typically enhance load capability performance as well as provide a more robust wear and support structure for the grate.
28. Grated Inlet
Referring to the point of a drainage system at which liquid enters, covered by a grate for the purposes of safety and debris filtration.
29. Grated Line Drain
A drain constructed along a single horizontal axis, grated across its entire length to allow liquid intake along its entire length. See Trench Drain. See Line Drain.
30. In-Line Catch Basin
A catch basin designed to the same specifications as the other elements of a drainage system for easy integration at any point in that system. It is typically located to facilitate attachment of an outlet or transmission pipe to evacuate water collected by the trench drain and may incorporate a debris trap.
31. Line Drain
See Trench Drain.
32. Modular Trench
A trench formed of multiple identical parts or modules. Alfa Channel is a modular trench system. EconoDrain and MultiDrain are modular, pre-sloped trench drain forming systems.
Pre-engineered metal trench forming/liner system manufactured by MultiDrain Systems, Inc.
34. Pathway Trench
A trench normally constructed for a specialized purpose such as cables, low voltage or steering wiring, piping conduit…etc. where the ability to access the materials housed inside the trench at some point in the future is a desired advantage. See Utility Trench.
35. Polymer Concrete Trench Drain
Trench drain composed of polymer concrete, which is created by mixing and curing a thermo-setting resin binder with materials like quartz, granite, and basalt. Its attributes include superior strength and corrosion resistance compared to Portland cement concrete (PCC). Alfa Channel is a Polymer Concrete Trench Drain system.
36. Pour-in-place Trench
Describing the element of design and construction of a trench drain forming system utilizing pre-set forms or a trench forming system to define the characteristics of the finished product. See Cast-In-Place.
37. Pre-sloped Trench
A trench constructed to predetermined slope specifications of varying degrees.
38. Site Drain
Term describing the drainage system determined ideal for a specific location or site, or the existing drainage system at that site.
