Snake fencing products have been used nuclear power stations, flood alleviation projects and road and rail schemes across the Country. This system is designed to be used in areas where vegetation management is not possible along fence lines and where additional height is needed to prevent snake access. Herpetosure snake fencing has an above ground height of 900mm and panels are supplied in three metre lengths.

The fence panels are fitted either into a 300 x 50mm slit created by a V backed sub soiler or “wiz” plough pulled by a tractor or in a trench excavated using a chain trencher or mini digger. Alternatively, if necessary, the trench is dug by hand. The preferred method for best results and most efficient fitment is the slitting method, where conditions suit. Once the panels are sited the slit is closed up by driving back along the line of the fence with a tractor, vehicle or compacted by hand. This creates a total seal between the soil and panels, which are fitted to the side of the trench nearest to the relevent population or the inside if a containment area. The panels are overlapped by 50mm then secured by aluminium blind rivets along the overlap joint and supported by stakes. Panels can be cut down or the overlap increased to allow for uneven ground or contours.
