Slot vs Trench Drain Solutions for Deck Drains

Deck drains are known for their advantage of rapidly evacuating surface water, or as is sometimes the case, containing chemical spills. Depending on your specifications, you can choose between a slot, trench or French drains. The latter is often confused for a trench drain as they both consist of troughs to cater for this drainage. However, French drains are distinguished by their perforated pipes that are buried in gravel, which in turn evacuate ground water.

Trench Drain

Their narrow widths and long lengths characterize these drains. Since they are used for the rapid evacuation of water, they are commonly made out of concrete. If slopes are involved, the drains are lined by polymer. They are not corrosion resistant.

Slot Drain

A slot drain, on the other hand, consists of a thin, one piece system with a linear slot at the top. The only part exposed is the surface inlets, which are made out of stainless steel. They are versatile, as they do not need any grating, allowing them exceptional sanitary qualities. They are also the most durable surface drain solutions and can be custom made to suite the particular deck drain when it comes to the question of depth or flow. Because they do not absorb any contaminates, cleaning slot drains is only a matter of hosing them down. Their installation also saves you cost, as it eliminates extra trenching, piping and backfilling, making them the superior choice over trenches.
