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.
