Slot Drain® Systems

Pre-sloped, prefabricated slot drain system


When Slot Drain was first introduced, grating, trench drains and four-sloped floors were standards in the drainage industry. Slot Drain changed surface drainage forever by providing the first pre-sloped, prefabricated drain system available. In doing so we provide an open floor drain system that is superior in many ways.

Slot Drain is a one-piece, built-in sloped, open floor drain / surface drain system with a linear slot on top, that is unlike anything else. The linear slot eliminates the need for grating, making it the most durable, sanitary and cost effective drainage system available. It’s applicable wherever floor or ground surfaces are subject to fluids, or have frequent cleaning requirements. Most Slot Drain applications are slab on grade, but it can also work in structural slabs and hollow core slabs. Overall, it replaces trench drains, with a self-cleaning system, at a significantly reduced cost.

Slot Drain was patented in 1988 and was the first floor drain on the market in North America to utilize the innovative prefabricated, pre-sloped and slotted concept, reducing construction labour costs. Since then, it has been installed successfully in hundreds of applications, satisfying both customers and construction professionals alike.

Four-sloped floors, or contoured floors, are replaced with effective, low maintenance and low-cost, two-sloped floors. Gone are the metal gratings and metal covers that are a nuisance to remove and clean. It’s available in stainless steel, with T-Sections, 90° and 45° elbows to go around corners and other obstacles.

Versatile, Durable & Sanitary

A big part of what makes Slot Drain so versatile is that there is no grating. In addition to common drainage use, this makes Slot Drain especially suitable wherever grating is not desired. Some examples would be: areas subject to heavy/high traffic and food and drink processing facilities with frequent inspections/cleaning requirements. Part of what makes Slot Drain suitable for these applications is its durability and sanitary qualities.

Slot Drain is the most durable surface drain system on the market. The only parts of the drain exposed are the surface inlets which are made of stainless steel (for stainless steel drain sections) and galvanized steel. The rest of the drain is embedded into the concrete, so it can handle whatever weight you want to put on it. There is no grating, which deteriorates / breaks / bends and needs replacing. This makes it especially suited for heavy/high traffic areas, such as airports, parkades, warehouses, truck and rail loading docks.

Slot Drain does not have grating to trap contaminants/bacteria, etc. A simple hose down of the floor is all that is required for cleaning. Also, Slot Drain does not absorb water/contaminants and allows contaminants to be disposed of in an environmentally manner. Another major benefit of Slot Drain is that flush valves can be added to the shallow end of the drain and set on timers or flushed manually in order to remove any sediment or contaminants automatically.
