When it comes to surface drainage, the most common type of drain seen in public applications is a grated drain. In contrast, U-drain is a trench drain with a single narrow “slot” intake that features no grates. The question is, which is the better option? In this article we examine three key factors that play into choosing a drainage system; durability, maintenance and aesthetics. Within each of these factors we will compare the grated vs. trench design.
- Feature a wider intake where grates act as a “bridge” between the two sides and handle traffic over the intake void.
- Grates must be built heavy enough to handle load over the intake void (this often translates to increased material costs).
- Over time, grates can bend/warp under the pressure of regular traffic and must be removed and replaced.
- Many grated drain systems feature trenches constructed out of cement or plastic, which can breakdown and/or damage easily.
- Debris is caught by the grate and eventually the grate is clogged at which point the grates must be removed and cleaned.
- No grates to clog up. Simply clean out the drain trench by inserting a cleaning paddle and dragging it along the drain to the sump pit.
- A Flush Nozzle is available which allows you to connect a pressure washer line to the drain for an efficient flush clean.
- Grates have a large and more defined footprint
- Grates can rust over time
- Grates can collect debris and bacteria
- Narrow intake is low-profile and does not stand out
- Drain edges are neutral and blend with the surface material
- Galvanized or Stainless Steel finish prevents rust
When you take the factors of durability, ease-of-maintenance and aesthetics into consideration, which drainage system do you think is best?
