⏱️

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.

👷
