Parking curbs and traffic barriers are most often installed on asphalt. Asphalt is typically 2″ to 4″ thick and underneath it there can be a variety of materials from soil to gravel.
Concrete traffic barriers can weigh 1,000 lbs or more depending on the size and usually do not require anchoring. You can drive spikes into the ground beneath them or cut out the asphalt and remove a couple inches of material to create a hole to set the barrier into for additional support.
Installing into blacktop: Both concrete and rubber curbs are secured using 14″ long spikes made of steel rebar. Simply set your curb in place and drive the spikes into the ground through the curbs mounting holes using a sledge hammer. Using a caulking gun to apply construction adhesive to the bottom of the curb before setting it in place can also help keep the curbs in place.
Installing into concrete: Both concrete and rubber curbs can be fastened with wedge anchors about 3” – 4” longer than the height of the curb and usually 1/8” smaller in diameter than the hole size. Simply set your curb in place and drive the spikes into the ground through the curb mounting holes using a sledge hammer.
