Our trench liner is a waterproof material that is composed of HDPE. Designed to be rugged and able to withstand the demands of a job site, the material is puncture and tear resistant while still retaining flexibility. When installed as a trench liner the HDPE is typically laid in the excavated trench with rocks placed directly on top. If multiple pieces are joined to line a long trench the material can be overlapped and connected using our HDPE double sided seam tape (not included).

The HDPE trench liner is available in roll widths racing from 18” to 60” and from thicknesses racing from 40 mil to 100 mil. Rolls are available in 100’ lengths. The material is made in the USA.

Please Note: The widest rolls that we offer in HDPE are 96” (8ft).

We are also unable to provide custom roll lengths on orders less than 50 rolls.

We also offer rigid HDPE in 48” x 96” sheets in both black and white colors.

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.
