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.
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.
