Protecting Vehicles from falling off wall.
Protecting Vehicles from falling off wall.
(OP)
Okay Engineering types, I have a large parking lot which is bordered at one end by a 16 foot tall Keystone type wall. The top of the wall is at parking lot level(parking lot is on fill). The edge of the wall is 4 feet behind a 6" tall by curb. I have about 100 feet I need to protect. The vehicles are mainly semi-tractor trailers with lots of turning movements in this area. Plus it is down hill from truck parking to wall at a 5% grade. My first thought was a standard CalTrans Guard rail. Then I started wondering if there are more economical methods...Any suggestions? Maybe a tall curb? But how tall?
Thank you.
Thank you.

For only 100' of protection, in place of guardrail it could be cheaper to go with some form of a concrete (Jersey) barrier.

I would kind of like to stop her.

If anyone dares to hit the wall, they won't leave.

Containment kerb is not really meant to be hit square on, but the 300mm/12" upstand should at least give an indication to a driver there was some hazard behind him him if he hit it. Paint it alternately yellow and black and there's a visual deterrent too. However, this would still need some sort of parapet to stop 'determined' drivers.

Bear in mind, also, that tractor trailers have big tires, and a 6" curb might not be much of a barrier to a truck. I'd suggest something much taller, like 12"
