About Toad Fencing

Fencing specifications

Toad fencing panels come in two sizes. Temporary panels measure 3000 x 750 x 3.5mm, in green recycled polypropylene. Permanent panels measure 3000 x 750 x 4mm, in the same material.

Fitted measurements

Panels are fitted 300mm vertically below ground and 375mm vertically above ground.

Fitting description

Panels go in either a 300 x 50mm slit cut by a V-backed subsoiler or ‘wiz’ plough pulled behind a tractor, or a trench dug with a chain trencher or mini digger. Where machinery cannot get access, the trench is dug by hand instead.

Where ground conditions allow, slitting is usually the preferred method: it gives the best results and fits the panels most efficiently.

Once the panels are in place, the slit is closed by driving back along the fence line with a tractor or other vehicle, or by compacting it by hand. This seals the panels against the soil. Panels sit on the side of the trench nearest the relevant population, or on the inside if the fence forms a containment area.

Panels overlap by 50mm and are joined with aluminium blind rivets along the overlap. Panels can be cut down, or the overlap increased, where the ground is uneven or contoured.
