Drain tile
Drain tile is a perforated pipe around the foundation that collects groundwater and carries it away.
Why it matters
It reduces water pressure around the foundation and helps keep basements dry.
Where people get this wrong
Drain tile needs a place to send water, like daylight or a sump pump. It can clog if installed without proper gravel and filter fabric.
Real-world example
A basement stays dry for years, then a wet season hits and water shows up. The drain system may be missing, clogged, or overwhelmed.
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.
