Threshold Drains Guide Banner

Threshold drains are a handy way to help prevent water from pooling in front of your doors or on paved outdoor areas. Installing a threshold drain is a relatively straightforward project that can save you from inconveniences and in the worst-case scenario, water damage.

What is a Threshold Drain?

A threshold drain is a small, shallow channel drain that is installed along the exterior side of door thresholds or in between paving slabs, etc. It catches water that accumulates on the ground and funnels it away to an underground drainage system to prevent flooding or water damage in your home.

Threshold drains typically consist of a PVC or metal channel with perforations to allow water to drain through. They often have an end cap on one or both sides to enclose the channel and the drain attaches to the floor surface.

Why Use a Threshold Drain?

Threshold drains serve several useful purposes:

  • They prevent water intrusion under doors. This is particularly helpful for exterior doors that are exposed to rain and snow, the drain catches water seeping underneath and diverts it away.
  • They stop large puddles of rainwater from accumulating outside of your front and back doors, stopping your shoes from getting wet every time you leave the house.
  • They drastically reduce the amount of water that collects in communal outdoor areas, allowing them to be used more frequently and with less hassle.

Where to Install Threshold Drains

Typical locations to install a threshold drainage system include:

  • At exterior doors - Any doors that lead outside are prime candidates for a drain. This includes entry doors, patio doors, garage access doors, etc. The drain will catch rainwater driven by wind under the door as well as water that pools in front of it.
  • In communal outdoor seating areas - This will help any gathering area look more attractive and allow it to be used more frequently as water will not be allowed to remain there.
  • Along walkways - draining water from paths that are subject to high foot traffic is essential, not only for the convenience of its users but also for accessibility.
