Greenscapes - Model GS-110 - Root Barrier
A .25mm thick, single-ply polyethylene sheet used extensive GreenScapes assembly. GS-110 can also be used in deeper assemblies where no woody species are to be planted.
GS-110 is a 10-mil (0.25 mm) thick, single ply polyethylene sheet used as a root barrier with an extensive GreenScapes Assembly. GS-110 can also be used in deeper assemblies where no woody species are to be planted. GS-110 is manufactured with polyethylene resins that provide high tensile strength, high puncture resistance, low moisture vapor permeability as well as excellent resistance to root penetration and decay.
GS-110 is typically installed above the waterproofing protection course and below other components including insulation and drainage layers. GS-110 is primarily used in the Strataseal HR Protected Membrane Roof Assembly, Plaza Deck Assembly, Greenroof Assembly, or Landscaped Assembly as the root barrier protection layer. For applications that require a welded root barrier overlap seam use GS-120 Root Barrier.
Install GS-110 Root Barrier over the waterproofing membrane assembly. Unroll and install GS-110 over the waterproofing protection course with minimal wrinkles and air pockets. Overlap adjacent sheet edges a minimum 12” (600 mm) and tape with CETCO Seamtape. Extend GS-110 installation up all roofing termination points and flashing to provide total root protection to all roof/ flashing surfaces that will be subsequently covered with growing media.
Cut as required to fit around all penetration and drainage details. As applicable, seal all cut edges and seal around detail with Seamtape. As GS-110 Root Barrier is installed looselaid, temporary ballasting may be required prior to the installation of subsequent topping materials. Temporary ballast should be a material that will not puncture the root barrier such as sand bags and milled lumber. Upon completion of the root barrier layer installation, install subsequent toppings as soon as possible within 30 days to avoid prolonged UV exposure.
GS-110 is not designed for extended UV exposure. GS-110 must be covered within 30 days to prevent deterioration to the sheet.
GS-110 roll size is 15 feet (4.5 m) x 100’ (30.5 m) - 1500 sq ft (139 sq m) per roll. Typical roll weight: 74 lbs (33.5 kg).
