Bollards and Barriers for Parking Garages and Ramps: Practical Protection at Exits, Pay Areas, and Retail
Why parking garages need a different approach In most facilities, vehicles and pedestrians can be separated with distance. Garages compress everything: turning movements, ramps, columns, doors, and queue lines. That means the same site can have two different impact problems. One is common and low-speed, like a driver misjudging a turn at a ramp end. […]
Shallow-Foundation Wedge Barriers for Sites With Utilities and High Water Tables
The problem: you need vehicle stopping power, but you can’t dig. Many barrier projects start with a simple requirement: stop a vehicle from entering a protected area. Then the first test pit gets excavated and reality shows up: duct banks, fiber, storm drains, unknown utilities, or a water table that turns the hole into a […]
