It is important to install these inground one way traffic spikes with a catalyzed adhesive like 2 part construction grade epoxy. We can supply this material to you. If you simply use construction adhesive, like air-dry adhesive, you risk allowing the units to be stolen or loosen more easily.
2 simple steps... E-Z installation!
1) Prepare the installation hole by cutting a small swath into the asphalt or concrete that is about 1/2” wider than the recessed part of the unit (depth approx. 12” total) and fill the hole with about 6” of coarse gravel for improved drainage.
2) Mix and apply catalyzed epoxy to the undersides of the upper support flanges. Lower the unit into place, making sure that the road surface is clean and dry where it will contact the adhesive.
Follow the adhesive manufacturer’s instructions, but hot weather or applied heat can have the units ready to drive across in as little as 2 hours.
