🏗️ Concrete Installation Tips
Proper Measurements
Always order 10-15% more concrete than calculated to account for spillage and uneven subgrades.
Weather Considerations
Avoid pouring concrete in extreme temperatures. Ideal range is 50-80°F (10-27°C).
Curing Time
Allow concrete to cure for at least 7 days before subjecting it to heavy loads.
Subgrade Preparation
Compact soil and add gravel base for proper drainage and to prevent cracking.
Moisture Control
Keep concrete moist during curing process to ensure proper strength development.
Professional Help
For large projects, consider hiring professionals for proper finishing and structural integrity.
