Earlier in the year, I witnessed the installation of 40 LF of Polycast 600. Polycast 600 is a pre-sloped polymer concrete product manufactured by Hubbell. It is similar to many commercial grade products already out on the market. This particular product was sold with galvanized steel slotted grates and a steel channel protector. The channel protector (Polyguard) is a strip of galvanized steel that helps prevent premature edge deterioration of the polymer channel.

The job was located in the Pocono Mountains of Pennsylvania, earshot from the Pocono Raceway. The trench drain was to be installed in a new equipment storage facility. The floor of the facility was being pour at the same time as the drain in order to pitch the floor toward the drain.

Initially, the excavator roughed out a trench in which to install the drain. The site was already installed with gravel, but was not compacted.

(This will probably cause a problem in the future. The gravel base for trench drain and all concrete floor projects need to be compacted. This floor has an excellent chance of developing voids underneath the concrete in the future.)

The position of the drain was determined and a level line was set. Then, the trench was cleaned of debris to assure that the channels could be set without obstructions.

Next, the channels were set along side the trench in order that they would be installed. The highest number channel (deepest) was set at the discharge invert. The smallest channel number was set at the beginning of the drain flow path. For this particular installation, the channel protector and grates were both left in place. The grates were later protected with plastic sheeting prior to pouring concrete.

The discharge water was designed to exit the end of the drain through 4” PVC pipe. A hole was drilled through the foundation of the building for this pipe to exit. It was later tied into a drain pipe that took the water to a sewer.

Installation started with the deepest channel first, then proceeding upstream. The channels were connected to each other with an installation bracket and connected to ½” rebar (#4). This particular installation bracket is patented and used exclusively with the Polycast system. It makes installation easy. However, in this case, the installation would have been easier if the excavator hadn’t used so many large stones in the base. At times, large boulders have to be removed in order to hammer the rebar in the ground. No matter, the bracket was adjustable enough to line the channel up perfectly, even if the rebar stakes didn’t install perfectly.

From the photo to your left, you can get a better idea on how the Polycast installation chair works. Bolts from the installation chair fit into the “dimples” of adjoining channels to hold the channel tight. The bolts can adjust in our out to help align the channels left or right.  The chair can also be adjusted up or down on the rebar to keep the top of the drain (grate) on level.

Once the first few channels were put into place, the remainder of the installation went smoothly. The channels seemed to fall into the proper place when the installation chair was properly used. In the end, we had a 40 foot length of polymer concrete trench drain, suspended in air, and ready to be set in concrete.

There have been many people asking about it, and I’ve finally been able to gather some good information about decorative grating for trench drains. Take a look at the trench drain grating I have pictured in various articles in this blog. Only a few stand out as being “pretty” from an aesthetic or architectural point of view. I can almost guarantee that my article “Trench Drain in the Black Hills” will be noted as containing some attractive grating. Well, I have more to talk about on this topic, especially as it refers to “pretty” cast iron and bronze products. And, the good news is, I have three manufactures I can discuss.

I have to be honest. My interest in decorative trench drain grating is for material gain. I am looking for products to sell that give my customers selection and quality. The standard slotted and perforated grating, though functional, can get boring. I have had customers looking for products that give them a “look” that is in keeping with the theme of the house or community. Sometimes, galvanized steel slotted grating just doesn’t cut the mustard. Let’s discuss three manufacturers of ornamental or decorative grating.

Ironsmith— I’m starting with them for a purpose. This is a foundry in Palm Desert California with an additional manufacturing point in Mexico. They have a number of ornamental trench drain grating products. They advertise that they used 100% recycled materials to make their castings. I counted 8 different grating styles. However, only 3 of these had any “curviness” in the design (I like curviness). Most grate styles were some variation of a standard slotted or perforated ADA grate.

The Ironsmith products are available in 4, 6, 8, and 12 inch wide grates. In addition, you are able to purchase grates in iron, aluminum or bronze. So the variety is good. They also have 12” x 12” catch basin grates and tree grates. And, if that was not enough, you can purchase the frame and trench to use when forming a trench drain system.

The folks at Ironsmith are nice people to work with. They are eager to help. Their prices are affordable for the west coast. I had difficulty getting an affordable product from them to sell on the east coast. Nevertheless, they seem to have a good product. For more information, go to www.ironsmith.biz.

Urban Accessories — I think these guys are the oldest of all the existing ornamental grate foundries in the US. Urban Accessories was founded in 1972 by an architect who was inspired by the vision of Louis Sullivan to enhance the urban environment. This is the Tacoma, Washington foundry that I promoted in my “Black Hill Trench Drain” blog entry. I also saw products of theirs in the Epcott Center in Orlando, Florida.

Urban Accessories has a wonderful product line. Besides trench drain grates, they have a rich assortment of tree grates, bollards, building buttons, drain covers, manhole covers and more. You can purchase trench drain frames to go with their grates, as well. They have a nice catalog and good coverage with the architects who deal with hardscapes.

Too good to be true? Maybe so!!! I never had a very good experience trying to purchase product from these people. They were reluctant to work with me on requests for special items. I had a difficult time getting information from them or my phone calls returned. And, once I had made contact with my area sales representative, I didn’t feel confident that he really had all the knowledge required for this product line. In addition to all this, the prices for their products are very expensive. A reason for all of this is out there. Check out the next company.

Ironage — This is a new company that is making some waves in the industry. I think they are part of the reason that Urban Accessories seems “disorientated”. Apparently, a few of the top (and best?) Urban Accessories managers left and formed the new company – Ironage.

Compared to UA, Ironage’s product line is small. Don’t let this fool you. Their product line is growing, the design quality is great, and the marketing is the “missing link” in the industry. Listen to this…Where all other foundries have promoted a cast-in-place philosophy for trench drain marketing, Ironage has decided to make ornamental grating that fits the vast number of preformed or pre-sloped trench drain products that are currently on the market. If you want ACO, Mea-Josam, Polycast, Polydrain or NDS trench drain, you can still buy it and use the Ironage decorative grate. It is a wonderful idea!!
Affordable??? The answer is YES! Of all the companies I have mentioned in this article, Ironage is the most affordable. They have inventory on the east coast which makes the shipping of small orders even less costly. I’m excited about their future. Look them up on-line!

My daughter, Ligia, was in from Brazil to visit in March. We took one weekend and went to Washinton DC to see some sights. The weather was sunny, but cool. (I think I got sun burn and wind burn at the same time.)

While checking out the monuments (and getting a little sentimental), I was able to look at some trench drain. Let me show you two that were interesting to me.

Trench Drain at the Lincoln Memorial Steps – These drains must have looked beautiful when they were originally installed at the base of the granite steps leading up to the Lincoln Memorial. Now they sport a handsome green oxidation coat, which means the original finish must have been a brilliant bronze or brass. These 4″ wide drains are filled with dirt and sediment, an indication that they probably are not pre-sloped. (Maybe, also, an indication of the maintenance budget.) I’m not certain they are really needed here, anyway.

The monument would probably look nicer if these drains were put into service again. Any volunteers to help clean these out?

Trench Drain at the Native American Museum – If you like Native American culture and artifacts, this museum has something for you. I was impressed with a number of aspects of the building’s architecture. The granite trench drain grates running through the courtyard and water sculpture areas, in particular, caught my eye.

These grates are probably the most expensive pedestrian grates I’ve ever seen. Let’s not even talk about the percent open space for efficient water drainage…… You can see they are ADA approved, but I’m not certain if they are heel proof. Are those holes 3/8″ diameter or smaller ???

No matter, the weekend was beautiful and educational. Maybe you have a unusual trench drain system or grate you want to share. Let me know. Thanks……………….  Michael
