Connecting HDPE Pieces

There are two ways to connect multiple pieces of HDPE together. One method is to overlap the HDPE and use our double sided seam tape to connect the two pieces. The other method is to butt the ends together and use our 17 mil single sided seam tape to create a solid connection.

Overlap Method
(for underground installations)

The overlap method is best used when connecting two pieces of HDPE in a buried application. Due to the overlap, a ridge is exposed which is not ideal when installed in exposed vertical or flat installations in high traffic areas as there is a possibility of an object catching on the ridge and pulling the two pieces apart.

In a below ground installation, the large overlap area provides a more water resistant connection as well as enhanced protection against tree and plant root intrusion.

End to End Method (for exposed installations)

When installing HDPE on a wall, floor or anywhere that is exposed, the end to end method provides a secure connection and does not leave any ridges exposed to potential catching by a person or object.

    Simplify Your Fence Maintenance with Fence Underlayment

    Keeping the area around your fence tidy can be a constant battle. From controlling weed growth to maintaining a neat mowing line, the upkeep often requires extra time and effort. Enter Fence Underlayment—a practical solution designed to make fence maintenance easier and more efficient.

    What Is Fence Underlayment?

    Fence underlayment is a durable material designed to be installed flat beneath fences. It serves two primary purposes:

    1. Weed Prevention: By blocking sunlight, it prevents weed growth directly under and around the fence.
    2. Clean Mow Line: It creates a clear boundary, ensuring you can mow neatly along the fence without worry.

    This underlayment is especially useful for homeowners looking to minimize yard work and achieve a polished landscape appearance.
