Installing M30 Shallow Mount Crash-Rated Bollards in New Construction
Reliance Foundry’s M30 shallow-mount crash-rated bollards are ASTM certified and will withstand the impact of a medium-duty track (15,000 lbs) at a speed of 30 mph. They are designed to keep pedestrians and buildings safe by preventing dangerous vehicle intrusion.
For enhanced aesthetics, bollard covers can be placed over crash-rated bollards.

NOTE
- Welding is required for rebar mesh placed around bollard in new concrete. Follow applicable welding codes (ie: joint types, filler selection and proper process)
- To protect the finish, keep bollards in original packaging until the exact moment of installation.
- Handle with care to avoid scratching or damaging bollard surfaces as abrasions will lead to rust.
- Once scratched, bollards cannot be repaired to original form without re-finishing the entire surface.
Before installation
Study the site plans
Study the site plans and mark the intended location of each bollard on the plan.
Check for hazards
Always check for hazards such as water pipes, gas lines, and underground wiring before digging.
Note: You may need a permit to dig to certain depths or in certain locations.
Thread Rebar Through Bollard
Thread the 1000 mm long pieces of 16 mm diameter rebar through the holes in the bollard. Use the 500 mm pieces where the longer rebar would interfere with the bollard structure.
Prepare the site for concrete
Plan the layout and then dig a hole that is 1818 mm long x 1468 mm wide x 700 mm deep (71.6” x 57.8” x 27.6”)
Set the brace
Set a brace (concrete block or chair) at the bottom of the site.
This will elevate the bollard off the subgrade.
Place the brace such that the top of the bollard post is 1 meter (39.37”) above grade. The bollard post should be placed center width-wise and 22.91” [582mm] from the front of the hole.
Note the attack direction: the bollard is rated based on an impact from a vehicle travelling in this direction towards the bollard.
Lower the bollard
Using the attached eye bolts on the bollard, lower the bollard into the site and onto the brace. Use appropriate machinery, lifting straps/slings, and procedure for an off-center load (bollard is approximately 1,133 lbs).
As described above, place the bollard such that the top of the bollard post is 1 meter (39.37”) above grade. The bollard post should be placed center width-wise and 22.91” [582mm] from the front of the hole (note the attack direction in the diagram above).
Note: Crash-rated bollards are heavy—to prevent accidents and injuries, ensure the proper resources are available to set into place.
Install Rebar Mesh
Construct a rebar mesh in the holes surrounding the bollard. Follow appropriate structural welding codes for the types of welds and filler.
Use OD 16 mm rebar for the vertical pieces and OD 10 mm for the horizontal pieces. Use two layers of horizontal rebar. Follow the dimensions shown. Use as much rebar as possible but cut where interference with the bollard occurs.
Mix and pour the concrete
The bollard requires C40 concrete to be used. Ensure proper ratio of water and concrete mix. The concrete should have a similar texture to moldable clay.
Fill the site to the top with concrete until it is level with the surface grade. Fill the bollard pipe itself as much as possible.
Set the Bollard
Ensure the bollard is plumb
Hold a level against the side of the bollard and ensure that it is plumb.
Note: Once the concrete has cured, there will be no way to make any adjustments.
Inspect
Inspect the installation
From a distance, examine the plane of view.
Ensure the bollard is plumb to the surface, and the surface is flat.
Check the bollard for any signs of surface damage
Abrasions should be covered as soon as possible to prevent rust and ensure the proper life of the bollard. For damage repair or other servicing needs, please contact Reliance Foundry’s sales department.
