A removable bollard sits in a sleeve set in the ground, so you can lift it out when you need access. Getting the sleeve height and drainage right is the key. Here is how we recommend installing them.
A 71-second walk-through: hole depth and drainage, testing the lock, setting the sleeve 5 mm above the ground, concrete, and checking it is flush.
No sound needed. Every step is on screen.
| Set in | An in-ground sleeve, in concrete |
| Hole depth | 70 to 100 mm deeper than the sleeve |
| Sleeve height | About 5 mm above the ground |
| Concrete curing time | At least 2 to 3 days |
What to do depends on the surface you are installing into.
Cut a square in the bitumen the width of the bollard plus at least 100 mm, then dig out to at least 70 to 100 mm deeper than the height of the sleeve.
Core drill a hole at least 100 mm wider than the in-ground sleeve, then dig out to at least 70 to 100 mm deeper than the height of the sleeve.
Check before you dig or drill. Look for water pipes, gas lines and underground wiring, and keep the work area safe from traffic.
Mark where each bollard is going.
Check for water pipes, gas lines and underground wiring before you dig. Check the traffic too, so you, pedestrians and vehicles stay safe while you work.
Cut or core drill the hole to suit your surface. See the hole sizes table. The extra depth is for drainage.
Put gravel, blue metal or drain rock in the bottom of the hole so water can drain away.
Check the locking mechanism works before you set the sleeve in concrete.
Tape over the bottom of the sleeve to stop loose material getting in. The tape breaks down over time so water can drain. Stand the sleeve in the centre of the hole, with its top edge about 5 mm above the finished ground.
Mix the concrete as the bag instructions say, then pour it evenly around the sleeve. Build it up slightly towards the top edge of the sleeve so water runs away. Take care not to move the sleeve.
Check the sleeve is level and the bollard or top cover plate fits and sits flush with the top of the sleeve.
Allow at least 2 to 3 days for the concrete to cure. Damp weather and cool temperatures can slow this down a lot.
Every bollard has a data sheet with its size, wall thickness and fixing details, with drawings.
So rain water can drain away from the sleeve instead of sitting in it. Dig 70 to 100 mm deeper than the sleeve and add gravel, blue metal or drain rock to the bottom of the hole.
About 5 mm above the finished ground, with the concrete built up slightly towards the edge so water runs off.
Yes. Check the bollard locks and lifts out properly before you set the sleeve. It is much harder to fix once the concrete has set.
