Courtyard slot-drain threshold

A small courtyard with a concrete slot drain set across the threshold gives an enclosed space clean, discreet drainage exactly where water collects.

Conceptual design image. This visual is for planning inspiration, not a construction drawing or a completed customer project. Verify actual dimensions, drainage, utilities, structural support, local approvals, and site conditions before building.

Why this direction works

An enclosed courtyard has few places for water to escape, so a slot drain across the threshold intercepts runoff before it pools or crosses into the house. Done subtly, the drain reads as a single crisp line while quietly solving the drainage that a walled space would otherwise struggle with.

Finish and layout observations

Keep the courtyard a clean field and let the slot drain read as one fine line, set flush so it does not catch. Size the drain, its fall, and its outlet for the runoff the courtyard collects so it clears in a storm.

Circulation, drainage, and maintenance

  • Size the slot drain and fall for the runoff the enclosed courtyard collects.
  • Detail a clear outlet so the drain does not back up in heavy rain.
  • Set the slot flush and narrow so it stays subtle and does not catch.

What to verify before building

  • A drain and outlet sized for real runoff.
  • A fall that carries water to the outlet.
  • A flush, subtle slot.

Frequently asked questions

Why use a slot drain in a courtyard?

An enclosed courtyard has few escape routes for water, so a slot drain intercepts runoff before it pools or enters the house, discreetly. Size it and its outlet to the runoff.

Will a slot drain clog?

Any drain can clog without maintenance, so it needs accessible design and periodic clearing, but a well-detailed slot handles normal runoff well. Plan for cleaning access.

Practical next step

Start with a measured, editable estimate

Use the calculator for the concrete field that can be measured today. Keep steps, walls, utilities, drainage structures, shade supports, and other distinct construction elements separate until their real dimensions and support requirements are known.
