1. Dig a trench a few inches back from the building's foundation and where you plan to install the water barrier. The trench should be 2” less deep than the depth of the barrier that is to be installed. For example if you are installing a 30” barrier, dig a 28” trench.

2. Place the water barrier in the trench. If connecting two segments of barrier be sure to overlap the segments by 2 feet, use sealant tape vertically and horizontally to connect the seam. The taped overlap will prevent the ground water from flowing through the joint.


Other Applications:

HDPE water barrier can also be used as a root guard for trees, bamboo and weeds. When used as a root guard, the HDPE sheet effectively prevents the plant's root from spreading throughout the landscape.

    Water Barrier for an above ground pool.

    Posted by Rick B on Aug 20th 2016

    I used the HDPE Water Barrier as an exterior barrier for my above ground pool. I was partially burying the pool in ground to accommodate my slopes and wanted to protect the side walls from moisture, roots, and rocks. Found this material to be a good fit for my needs. It cuts easily, handles well, and was easy to install. I used tape to attach the material to the sides of the pool and used the back filled soil to hold it in place.
