The Antiburrowing Device is an additional physical barrier that is installed under the main fencing. The antiburrowing barrier is a physical barrier – a grid or barbed wire that is installed between the supporting posts of the fence and goes deep into the ground. The antiburrowing fences are necessary to prevent unauthorized intrusion into the restricted area by digging under the main security fence.
The antiburrowing barrier is used a part of perimeter security fencing systems. The“Topaz”fencing systems are recommended for use at the facilities of the fuel and energy complex and nuclear complex, as well as at high-priority, sensitive national facilities.
The principles of operation of the antiburrowing devices used in our perimeter security fences are:
Height (H) to be selected from the range: 500, 600 mm.
Width (S) to be selected from the range: 1000, 2500, 3000, 3100 mm.
The antiburrowing barriers as part of metal mesh fences are arranged to prevent trespassing into the protected area below the level of the leveled land of the perimeter security fence. The antiburrowing devise is installed between the posts as an extension of the welded panel under the ground.
Protecting facilities against unauthorized access by means of digging is a world practice. Similar measures are provided for at a number of high-security facilities that are subject to increased security requirements.
