Root barrier sheets prevent roots of trees from growing. Use it mainly in roadside trees, in the border of the garden, and around other trees. To use root barrier sheets, dig around trees to the vertical direction for width of the root proofing sheets, and install it and backfill it. When you use it around trees, stick the joint with exclusive tape.

There are two types of root barrier sheets we treat:

  1. Type to prevent roots with water proof sheets.
  2. Type to prevent roots with sheets which let water go, but have drugs that roots of plants dislike on the sheets.

You can’t install the root barrier sheets type 1 to the horizontal direction so that roots don’t come out to the ground. It is absolutely effective in vertical direction. The effect of the medicine in type 2 disappears after a period of time. You can choose root barrier sheets from two types depending on your situation.
