Water vole fencing is by far the most cost effecient, sustainable and durable on the market. Highly regarded by many ecologists as the most effective water vole barrier being used in mitigation, no other panel is designed to offer the same level of exclusion. Herpetosure water vole fencing has been used by developers, contractors and conservation bodies, including the RSPB

The fence panels are fitted either into a 500 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 vole 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. Fine weld mesh can also be employed to allow water balancing/ flow at ditch crossings etc (as shown).
