Installation Guidelines for Engineered Bollards

First, mark your installation points. We recommend your bollards be no more than 5 feet apart. Any space larger than this can fail to block the width of smaller vehicles.

After marking your installation points, use an auger to drill holes where you want to implement bollards and barriers. The hole itself will be significantly wider than the bollard or ground sleeve itself, as you need to leave room for installing a rebar reinforcement and filling the area around the bollard or ground sleeve with concrete.

At the bottom of the hole you drilled, you’ll need to add a layer of gravel that acts as a drainage point for ground sleeves. This prevents rain, snow, mud and water from accumulating in the ground sleeves for your removable bollards.

Next, you’ll want to prepare a rebar cage to your specifications and position it. A cylindrical rebar cage provides reinforcement for the ground sleeve or the bollard you plan to install — drop it in the hole and let it rest on top of the gravel.

Then, attach a PVC drainage pipe to the bottom of your ground sleeve and place it inside the rebar cage in the hole.

Once the drainage pipe is attached, you’ll need to properly position the sleeve. If you are installing ground sleeves for removable bollards, ensure that the surface of the ground sleeve is flush with the surface of the ground and level. If you are installing a surface mounted fixed barrier, ensure that it stands a full 36″ above the surface for the best level of protection.

Next, fill the hole with concrete and smooth it level with the ground—if you installed a ground sleeve, wait for the concrete to completely cure before installing your bollard.

Once the concrete is leveled with the ground (and completely cured if a ground sleeve is involved), you can insert your bollards to help ensure optimal protection for your facilities.
