Heat a large skillet over medium-high heat and add the ground beef. Cook and crumble for 7-10 minutes, or until the beef is brown and cooked through. Drain grease. Add the garlic and taco seasoning and stir in water. Bring to a boil until thickened, then reduce to a simmer. Stir in the refried beans until well combined and heated through. Remove and set aside.
Spread half of the chips in an even layer on a large, light-colored baking sheet.
Distribute half of meat mixture in scoops on top and along the sides. Sprinkle with half of the cheese.
