Essential Information for All Projects

Key considerations that apply across all concrete construction projects.

📋 Pre-Project Planning Checklist:

  • Building Regulations: Check if approval required - contact Local Authority early
  • Planning Permission: Verify if needed (driveways, extensions, conservatories)
  • Utilities: Call before you dig - locate underground services (gas, electric, water)
  • Access: Ensure concrete truck can reach site (or budget for pump hire)
  • Weather: Check 5-day forecast - avoid rain and freezing conditions
  • Neighbours: Inform about noise, delivery trucks, potential disruption
  • Materials: Order concrete 1-2 weeks ahead, especially during busy season
  • Labor: Arrange adequate help - concrete work time-sensitive
  • Tools: Hire/buy all equipment before delivery day
  • Contingency: Have backup plan for delays or problems

⚠️ Common Mistakes to Avoid:

  • Under-Ordering Concrete: Shortfall creates weak cold joints - always add 10% extra
  • Poor Sub-Base: Skimping on MOT Type 1 causes settlement and cracking
  • Wrong Concrete Grade: Using C15/20 instead of C20/25 creates structural issues
  • Inadequate Preparation: Not being ready when concrete arrives wastes money (waiting charges)
  • Adding Water: Excessive water drastically weakens concrete - never add on site
  • Insufficient Thickness: Too thin concrete cracks and fails prematurely
  • No Control Joints: Forgetting joints causes random ugly cracks
  • Poor Curing: Letting concrete dry too fast reduces strength by 30-50%
  • Ignoring Building Regs: Working without approval causes legal problems when selling
  • Rushing: Concrete work can't be rushed - allow proper time for each stage
