Proven long term root protection

What is BioBarrier?

  • A long-term root and weed control system.
  • Consists of controlled-release nodules impregnated
    with Trifluralin herbicide.
  • Trifluralin is non-systemic – therefore plants and
    surrounding vegetation are not harmed.
  • Toxicity level of Trifluralin is less than table salt,
    aspirin, nicotine and most major brands of lipstick.
  • Nodules are permanently bonded to 4 oz. Geotextile fabric.
  • It does not disrupt soul hydrology since water and nutrients pass easily
    through the fabric.
  • The only membrane homologated by PMRA (Government of Canada) for
    commercial and domestic application.

Protect your investment

Hardscapes and landscapes are a big investment, and traditional methods of protecting them have meant repeatedly spending time, effort and money. But a one-time installation of BIOBARRIER Root Control System or BIOBARRIER ® Weed Control System means years of security from roots or weeds growing where they’re not wanted. Constant maintenance is a thing of the past with these easy-to-use systems, allowing you to spend your time and budget in other areas.

Tree roots seek out air and moisture in the soil, causing expensive damage to underground infrastructure. BIOBARRIER’S unique geotextile design lends flexibility to surround infrastructure, extending the life of your investment

    Biobarrier® utilizes an award-winning, state-of-the-art technology. Developed as a long-term solution for vegetative root intrusion and possible structure damage, Biobarrier combines a proven geotextile fabric with a proven pre-emergence herbicide. The only active ingredient in Biobarrier, trifluralin, has been used extensively in commercial applications for more than 40 years and continues to be widely recognized as a leading pre-emergence herbicide.

    The patented controlled-release process, unique to Biobarrier, delivers only the amount of trifluralin biologically necessary to inhibit root growth. Biobarrier’s innovative technology ensures that precise amounts of herbicide will be dispersed at the correct location for an extended time. This provides a distinct advantage over repeated applications of herbicides required by conventional methods.

    On the following pages, standard installation procedures for a broad variety of Biobarrier applications are summarized. Should you require additional drawings or instructions, please call us.
