The new design eliminates hard edges and flashing made when using the old injection mold die. The new die gives the grates a smoother look and the Mini Channel system a cleaner appearance.

The new Mini Channel grate pattern isn’t just for appearance’s sake, either. The new mold lengthens the plastic grate’s supporting ribs, which run perpendicular to the trench’s length (think hamburger, not hot dog). Supporting ribs increase a grate’s longevity under traffic and serve to make the plastic channel grate sturdier. The better a grate’s support structure, the less vehicle stress will affect it.
While the updated look on the Mini Channel won’t increase the channel drain’s overall load bearing capacity, it does make the grate more rigid.
It is important to point out that this improvement didn’t increase the cost of the Mini channel grating. For an estimate on a Mini Channel system for your patio application, request pricing from one of the specialists at Trench Drain Systems today.
When I started my career with trench drain, I didn’t know the benefits of using plastic trench drains on drainage projects. Since then, I’ve seen enough projects to tell the difference between good and bad trench drain systems. From what I learned, all trench drain is good as long as you have the proper product for the application.
This is how you choose a plastic trench drain:
1. Is the drain located in an area with extreme freeze/thaw?
Plastic is more susceptible to freeze-thaw than other materials (such as metal or polymer concrete) used for trench drains. Plastic trench drains can separate from the concrete that holds them in place during extreme temperature changes. Also, PVC becomes brittle in the extreme cold and could crack under impact at those times. So, be aware of environment factors before you choose your trench drain material.
2. Is the drain being installed in a paver surface or in a pour concrete floor?
Trench drains used in paver patio applications usually are straight walled so to accommodate the close proximity of a paving stone. Plastic drains that have built-in pedestals or an exaggerated grating seat impart greater strength to the drain and are best suited for concrete installations.
3. Are the aesthetics important?
Narrow plastic drains, also called strip drains, come in 1-2” widths and don’t offer decorative grating options. Larger plastic systems (3” wide and larger) often feature decorative grating options in plastic, cast iron or stone. Some systems even use stainless steel grates. Or, how do you feel about the plastic channel edge being exposed at the drain-floor interface? There are systems which minimize or eliminate unsightly channel details.
4. What are the load requirements for the drain?
Not all residential-grade plastic trench drains are built with vehicle traffic in mind. But some applications, such as driveways, require load bearing drains. Small plastic channel drains are designed to incorporate the strength of the surrounding to achieve higher load standards. Often, these systems offer cast iron grates and reinforcing frames to assist in transferring the load away from the plastic channel. This allows the plastic channel to achieve industrial-grade load ratings.
5. Is the drain being installed by you or a contractor?
Superior trench drain design promotes easy installation. Engineers thought through the installation process to design easy-to-install trench drains. Plastic trench drains are lightweight and easier to handle. Still, some of the larger plastic systems can be unwieldy in inexperienced hands, especially when being installed in concrete.

Ever since the first line of plastic trench drains emerged on the market, homeowners have welcomed the convenience of lightweight, affordable drainage systems. Easily purchased and installed, plastic drains bring patio and driveway drainage systems to an accessible level.
But a lingering flaw in plastic drainage systems has been the same simplicity that made them popular. The smallest plastic drains are about 1.5” wide and, though they come in up to three colors (usually gray, sand or white), are just narrow strip drains with no ornamental grating options. Larger drains between 2” – 4” wide come standard with plastic slotted grates that offered new colors but no design improvements.
Now NDS’ design efforts allow anyone to buy decorative plastic trench grates for new and preexisting NDS drain systems. The new Botanical and Wave designs are both beautiful. (see a side by side comparison below). While the pattern options are still developing, both styles come in trademark NDS colors of sand, black, green and gray.
These grates are available for the 3” Mini Channel and the 4” Spee-D Channel systems, and they also work with 12” catch basins. Overall, I think the new decorative grates improve the 3” and 4” NDS profile drains. Let me show you why.
NDS Mini Channel plastic drain system
The Mini Channel and Spee-D Channel profile drains feature honeycomb chambers within the wall. Spee-D Channel drains (not shown here) have thicker walls to accommodate their greater width, but the basic construction is the same. Profile drain grates rest on a lip in the channel body and are screwed into place.

Traditionally, either system’s slotted plastic grates rest fully within the channel and do not hide its edge (see above photo, right). Gray channel edges are visible on either side of plastic slotted Mini Channel or Spee-D Channel grates, a detail frequently commented on in upscale applications.
“[The visible channel border] has been a long running criticism of the Mini Channel and Spee-D Channel,” says Mike Schreiber, District Sales Manager at NDS.
Personally, I always felt this was a design flaw on the part of NDS not only because water can gather between the grate and the channel but also because it’s not aesthetically appealing. I’m pleased that NDS is taking steps to improve on the design.
NDS’ decorative grating (see above photo, left) is thicker. The grates hang over the channel walls. Once installed, all you see of the drainage system on the left is the Botanical pattern grate.
The photo above shows how nicely the new decorative plastic grates fit into NDS profile drains. I do like these grates better because their added thickness makes the systems more durable. It also makes the grates sit higher in the channel, which means you’ll have to use special screws to secure the grates.
At first I was concerned that the additional height would tempt the Fates and lead to broken drains. However, NDS specifications recommend profile channels be recessed up to a quarter inch to improve drainage. Recessed drains also protect the channel from snow plows, which have been known to tear up grates. If there are any issues they will probably occur in preexisting drains that were not installed in a recess. But if the existing drains were installed properly there shouldn’t be a problem.
When decorative cast iron grates became a reality for homeowners, plastic drain manufacturers realized they were missing out on a large market. Contractors and homeowners saw cast iron grates as an upgrade to basic slotted plastic worth the extra cost, but decorative plastic was unsold real estate in the trench drain market. So far, only NDS has done anything to fill the market need.
Seeing an unmet market need, NDS began developing their line of decorative plastic grates a year ago. The manufacturer conducted surveys among customers and contractors to help choose which designs would be most popular before sending out small batches for trial runs. The end result is that homeowners can now buy Botanical and Wave pattern plastic grates for their profile drains and catch basins.

The decorative grates are making in-roads on applications where drainage systems are visible such as commercial pools, patios and sidewalks. While they aren’t driving new sales – nobody who doesn’t need a trench drain is buying the grates just to have them – homeowners and contractors lean toward decorative plastic because of its improved aesthetics.
“I’m really starting to see the decorative channel take off,” Schreiber says.
Many NDS drains have a decorative iron option available (see our blog about decorative cast iron grating here). Plastic decorative patterns are still limited at the moment, but I expect options to expand once the idea of affordable plastic replacement grates sinks into the public’s mind. NDS, now busy incorporating new acquisitions such as KBI flow control and ADS drainage systems, is going to wait before expanding their decorative offerings.
