Embedded and removable bollards have a more involved installation process than surface-mounted alternatives, but this can ultimately make them longer-lasting and less susceptible to tampering. To install removable bollards, you'll need to drill through the installation site using an powered auger, creating a hole significantly larger than the diameter of the bollard itself.  At the bottom, you'll install gravel and a rebar cage to facilitate moisture drainage and reinforce the bollard.  Finally, you'll install either the bollard itself or the removable bollard's ground sleeve, holding it in place while you fill the hole with cement.

Surface-mounted bollards and barriers can be considerably simpler and faster to install, as they do not necessarily require the same materials or process.  In instances where a pre-existing concrete slab is in place, collapsible and fixed bollards can often be mounted directly to the slab with drill in concrete anchors.  In applications where the bollard is installed in asphalt or dirt, a footing is recommended taking into account the frost line in a given region.  Surface-mounted posts come in two types: collapsible and fixed.
