Trench drain
A trench drain is a long drain channel in a floor that collects water and routes it away.
Why it matters
It can help garages manage snow melt and water, especially when a flat driveway or layout makes slope tricky.
Where people get this wrong
A drain needs a place to send water, and it must stay clear of debris. Some areas restrict floor drains connected to sanitary sewer.
Real-world example
You wash the car in the garage and the water runs into a trench drain instead of pooling in the corner. That is the drain earning its keep.
Where this hits your build
This matters during site work and foundation. Mistakes here get buried and are expensive to fix later. Pay attention before concrete is poured.
