You asked, we listened. Find answers to all your technical questions about Polycast trench drains, catch basins and accessories as well as installation tips and chemical resistance guidelines.  Be informed before you buy!

What is temperature resistance of Polycast's polymer concrete drains?

Polyester resin polymer concrete is able to safely handle temperatures up to 150 degrees Fahrenheit without structural damage.  For applications with higher temperatures, Polycast manufactures special vinyl ester polymer concrete channels that withstand greater heat.

What is the chemical resistance of Polycast trench drains?

Corrosion resistance varies depending on the chemical.  Please review the Polycast Corrosion Resistance Guide for more information.

How wide is the Polycast 600 Series?

Polycast 600 Series, Polycast 500 Series and Polycast 900 Series utilize a 6.25" (OD) polymer concrete channel.  With a 4" interior channel width, these drain systems have thicker walls than the competition and use the same 5.25" wide trench drain grates.

What does Load Rating mean?

Polycast measures trench drain compression resistance - how much weight a trench drain can withstand without structural damage - based on DIN 19580 international guidelines, which separate drainage applications into six categories:

  • Load class A icon Load Class A
    3,372lbs. - 15 kN
    Residential, pedestrian, and cyclist traffic
  • Load class B icon Load Class B
    28,100lbs. - 125 kN
    Sidewalks, parking lots, and car parking decks
  • Load class C icon Load Class C
    56,200lbs. - 250 kN
    Curb sides, highway shoulders, and parking areas
  • Load class D icon Load Class D
    89,920lbs. - 400 kN
    Trafficked sections of roads and highways
  • Load class E icon Load Class E
    134,800lbs. - 600 kN
    Industrial areas, forklifts, traffic, ports, and dock sides
  • Load class F icon Load Class F
    202,320lbs. - 900 kN
    Aircraft runways, docks, and high-impact wheel loads

What is the slope of Polycast trench drain?

The Polycast 400 Series, Polycast 800 MAXI and the low profile Polycast 500 Series are non-sloped drainage systems.

Polycast 600/700 Series and 900 Series have a built-in .65% slope. These Polycast systems also offer neutral channels to extend the length of the run.

The 3000 Series, FP0800 Series and FP1200 Series offer fiberglass channels with .5%, .75%, 1% and 1.25% built-in slopes.  Contractors may also use neutral, non-sloped channels to extend the length of trench drain runs.

Why does my trench drain need a frame?

Frames reinforce a trench drain's channel body, protecting the polymer concrete from exposure that stresses the drainage system.  With a frame, Polycast polymer concrete trench drain systems can handle heavier loads, earning them a higher load rating.  Polycast fiberglass channels incorporate integral frames, which increase durability over competitive brands such as ACO trench drain, MEA-Josam, and Zurn trench drain.

Where do I download technical specifications for Polycast drains?

What are Polycast polymer concrete benefits compared to J.R. Smith and ACO trench drains?

Polycast polymer concrete 6.25" wide trench drain channels mean a wider interior width and more water flow than similar trench drain systems.  Polycast's 48" channels mean fewer channels and joints than similar concrete ACO drains.  With fewer accessories, Polycast offers a price advantage in 6" systems over ACO and J.R. Smith trench drains.

How do fiberglass Polycast trench drains compare to Zurn Flo-Thru trench drain systems?

Polycast channels offer larger flow capacity than similar products.  Thicker channel walls make Polycast fiberglass drains more durable than ACO and Zurn drains.

Why do I need a project layout?

Trench Drain Systems requires all customers purchasing pre-sloped trench drain systems to sign off on a project layout.  This ensures that outlet depth is correct, preventing costly error and allowing us to ship your order more efficiently.
