Bollard Installation Instructions

1. Check for utilities and perform a visual inspection for any obvious obstructions. Scan for live cables and any underground services with a cable avoidance scanner. Once you know you're good to go, mark out the area to be excavated.

2. Excavate a bore hole to approx 300mm x 300mm square. Larger bollards will need a bore hole of approx 400mm x 400mm square. 

3. For concrete or tarmac, you will need to use a stone cutting saw with an appropriate diamond blade, and for block paving, simply remove the blocks away from the around the bore hole. Try to ensure you align the bollard adjacent to the pattern of your paving.

4. Excavate a hole down to the full depth of your bollard and allow for an additional stone base of 10mm of 20 mm stone for drainage. Once you have reached the required depth you are now ready to begin lowering the bollard casing into the ground.

5. If a root bar is supplied with your bollard ensure it is fitted into the base of the outer casing. Lower the casing into the bore hole and ensure the top of the casing is flush to the surface level.  

6. Raise the inner bollard into the upright position, and check to ensure the bollard is level to all plains when raised. When level, and to steady the casing, back-fill 20mm stone around the casing to a depth of 20mm.

7. When you are satisfied the inner bollard is vertical and plumb, lower it back into the outer casing and raise it up again to check for it’s smooth operation.

8. Gradually back-fill around the outer casing with 20mm shingle until the level is approx 400 mm from the top of the outer casing.

9. Fill the remainder of the bored hole around the casing with a good concrete mix to a medium wet slump. Before the concrete has hardened and set, lower and raise the inner bollard to double check that it is still vertical to all planes.

10. Once you are totally happy then lower the inner bollard back into the outer casing and begin to reinstate your existing surface.
