Bollard Installation
Every storefront we replace bollards at has the same story — somebody's foot slipped off the brake, the car came through the window, the insurance claim was bigger than 30 years of bollards combined. Bollards are cheap. Replacing the storefront, the inventory, and the employee on the wrong side of the glass is not.
We install schedule-40 steel, crash-rated K4/K12, removable, and decorative bollards across MT, ID, WA, ND, and SD. Saw cut, footing, install, patch, stripe — one crew, one warranty.
Bollard Types We Handle
From standard storefront protection to K-rated anti-ram. We help you size it to the actual risk, not the brochure.
Storefront & ATM Protection
6-inch schedule 40, concrete-filled, 36-inch footing. The default for retail, banks, and fuel islands.
Crash-Rated K4 / K12
ASTM F2656 rated bollards for government, drive-up windows, and any asset where a passenger vehicle isn't the worst case.
Removable Bollards
Sleeved sub-grade mount with padlock — loading docks, fire-lane access points, and event-controlled areas.
ADA Spacing Layout
We measure clear span between bollards so wheelchairs and walkers pass through without the layout failing an ADA walk.
Which Bollard Stops What
| Type | Spec | Typical Use |
|---|---|---|
| Concrete-Filled Steel (Standard) | 6 in. OD, schedule 40, 36–48 in. above grade, 36 in. below grade in concrete footing | Storefronts, ATMs, fuel islands, transformer protection |
| Heavy-Duty Crash Bollards (K4 / K12 rated) | 8–12 in. OD, embedded footing 48–72 in. deep, rebar cage | Government facilities, drive-up windows, anti-ram applications |
| Removable Bollards | Sleeved sub-grade mount, padlock or keyed lock | Loading docks, fire lanes that need occasional access, event-controlled areas |
| Decorative Sleeves | HDPE or stainless cover over a structural steel bollard | Hospitality, retail, mixed-use developments where aesthetics matter |

Bollard Installation Questions
How deep does a bollard footing need to be?
For a standard 6-inch schedule 40 steel bollard taking light to moderate vehicle impact, we pour a 36-inch-deep, 18-inch-diameter concrete footing. K4/K12 anti-ram bollards go 48 to 72 inches deep with a rebar cage and an engineered footing per the manufacturer's drawing. Surface-mount-only bollards are rarely worth the install — first impact rips them out of the slab.
What size bollard do I need to stop a car?
A 6-inch schedule 40 steel bollard set in a 36-inch concrete footing will stop a passenger vehicle at typical parking-lot speeds (5 to 15 mph). To stop a commercial truck or stop a vehicle at higher speed, you need an engineered crash-rated bollard (ASTM F2656 K4 or K12). We help you size it based on actual approach geometry — not just "how big does it look."
How far apart should bollards be spaced?
ADA requires bollard spacing greater than 36 inches clear so wheelchairs and walkers pass through. Storefront protection typically runs 48 to 60 inches on center — close enough to stop a vehicle, far enough for a shopping cart. We measure based on the asset behind the bollards, not a generic rule.
Do you handle the asphalt or concrete cut?
Yes — saw cutting, core drilling, concrete pour, asphalt patch, and final stripe restoration are all part of the bid. One crew, one mobilization, one warranty.
Can you replace a bollard that's been hit?
Yes. We pull the damaged bollard and footing, re-pour, and reinstall with the original spec or upgrade to a heavier bollard if the impact history calls for it. Most replacements take a single day per bollard.
What does bollard installation cost?
Standard concrete-filled steel bollards installed run $450 to $850 each in MT, ID, WA, ND, and SD — includes saw cut, footing, bollard, paint or sleeve, and asphalt patch. Crash-rated K4/K12 bollards run $1,800 to $4,500 each. Volume discounts kick in above 6 bollards per site.
