Root Barriers protect your foundation from tree and shrub roots. These roots typically move laterally toward the foundation seeking moisture. We use "Bio Barrier" Root Barrier made from a geotextile fabric mesh impregnated with polypropylene capsules. These capsules release an environmentally friendly chemical (Trifiuralin). This chemical forces roots to grow away from the foundation or below the 19" depth of the fabric. The chemical is released over a 50-year period. These rolls of fabric come in 100' lengths. Trenches are dug and this fabric is tacked to the earth's wall.
This root barrier fabric is easier to work with and provides a continuous uninterrupted line of protection compared to polyethylene sheets of corrugated fiberglass that leave sections (overlaps) vulnerable to root penetration.
