One-way fencing is a specifically designed amphibian and reptile fencing system which allows animals to move outside of the construction zone whilst preventing them from re-entering. Herpetosure one-way panels have two bends which when installed creates a fence that sits at a 45 degree angle.This angle coupled with a textured upper panel surface allows reptiles and amphibians to grip and scale the fence to leave the site.

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 relevant population or the inside if a containment area. The panels are overlapped by 50mm then secured by aluminium blind rivets along the overlap joint. Panels can be cut down or the overlap increased to allow for uneven ground or contours.
