A rain barrier stops rain from coming under your garage door by placing it in front of your garage door to block any rain or flood water from entering your garage in the first place.

Trench Drain

If you’ve ever opened a history book, you are probably familiar with using trenches in defensive warfare. A trench drain provides that same defense against rainwater entering your garage. A trench drain is most useful if your garage is downward in relation to your yard instead of above it. By installing a trench drain, you can ensure that the rainwater is directed away from your garage towards another area.
