Bottom of Fence Gap Barrier


SKU MM-HDPE-18-40-100

The under fence gap barrier is ideal for situations where there is a large gap in a bottom of a fence which needs to be blocked. Our barrier is constructed of HDPE and is available in thicknesses; 40 mil, 60 mil and 80 mil. The material is waterproof and can be used to direct water along a fence line or away from any landscape structure or hardscape.

To install, dig a trench below the fence, drop the barrier vertically in the trench and then using screws and washers (not included), attach the under fence gap barrier to the bottom of the fence. Finally, backfill to securely hold the barrier in place.

The material is available in either 10”, 18", or 24” heights and can be easily cut down to match the specific depth that you choose to dig.

The barrier is available in 100’ rolls and is made in the USA.

Note: Our HDPE plastic is only available in roll widths up to 60 inches.

Please note that we are unable to provide custom roll lengths.
