Concrete Pad

1. If concrete pad is required, the guardrail post is extracted first from the footing. 
2. A square pit by the dimension of 300 mm x 300 mm x 200 mm (as shown in the drawing) is dug.
3. The guardrail post then place into the pit, suspended to the required height.  String can be used to ensure uniform level is achieved on all the selected raised guardrails.
4. Concrete grade 20 is then poured into the pit, properly compacted and let to cure for 3 days.
