Here's a step-by-step guide on how to construct a road kerb:br br Preparationbr 1. *Design and planning*: Ensure you have a detailed design and plan for the kerb construction, including the type of kerb, materials, and dimensions.br 2. *Site preparation*: Clear the area of debris, vegetation, and obstructions. Conduct a survey to identify any underground utilities.br 3. *Marking and alignment*: Mark the kerb alignment using stakes and twine or a laser level.br br Materials Neededbr - Kerb stones or concrete kerb unitsbr - Sand or cement mortarbr - Aggregate base material (e.g., crushed stone)br - Geotextile fabric (optional)br - Concrete (for haunching and jointing)br br Construction Stepsbr 1. *Excavation*: Dig a trench for the kerb, about 150-200 mm deep and 300-400 mm wide.br 2. *Laying the base course*: Place a layer of aggregate base material, compacted to provide a stable base.br 3. *Laying the kerb stones*: Begin laying the kerb stones or concrete kerb units, starting from one end. Use a spirit level to ensure the kerb is level and plumb.br 4. *Jointing and haunching*: Fill the joints between the kerb stones with sand or cement mortar. Apply concrete haunching to secure the kerb stones to the base course.br 5. *Compaction and finishing*: Compact the kerb stones and base course using a plate compactor or hand tamper. Finish the kerb by applying a layer of sand or cement mortar to the joints.br br Safety Precautionsbr 1. *Wear personal protective equipment (PPE)*: Hard hat, safety glasses, gloves, and steel-toed boots.br 2. *Ensure proper excavation and trenching*: Follow safe digging practices to avoid accidents.br 3. *Use proper lifting techniques*: Lift heavy kerb stones and materials safely to avoid injury.br br Quality Controlbr 1. *Check kerb alignment and level*: Ensure the kerb is properly aligned and level.br 2. *Verify jointing and haunching*: Check that the joints are properly filled and the kerb stones are securely haunched.br 3. *Inspect the kerb for damage*: Check the kerb for any damage or defects during construction.br br Remember to follow local building codes, regulations, and standards for road kerb construction.
