Subrasante y base
Punto críticoCómo verificar
1. Verify base material depth (4-6" for concrete, 6-8" for asphalt driveways)
2. Check compaction — surface should feel firm, no soft spots
3. Verify grading slopes away from garage and house (minimum 1/8" per foot)
4. Check that topsoil and organics were removed before base was placed
5. Verify subgrade drainage — no standing water issues in the area
6. Check base extends at least 12" beyond driveway edges
Problemas frecuentes

- Poor compaction — driveway cracks from settling
- Topsoil left under base — decomposes and settles
- Wrong slope direction — water runs toward garage
- No edge support — driveway cracks at edges
