Concrete Project Tips
📏 Accurate Measurements
Always measure twice and order 5-10% extra concrete to account for waste and slight variations in depth.
🌡️ Weather Considerations
Don't pour concrete in freezing temperatures or during rain. Ideal temperature is 50-70°F.
💧 Proper Curing
Keep concrete moist for at least 7 days after pouring for maximum strength development.
🏗️ Base Preparation
Proper base preparation with gravel and compaction is crucial for long-lasting concrete.
⚡ Quick Setting
Concrete starts setting in 30-60 minutes, so have your tools ready and work efficiently.
🔨 Reinforcement
Consider rebar or wire mesh for slabs over 4 inches thick or in areas with heavy loads.
