<br />24" DeepRoot® Tree Root Barrier
<br />Specified tree root barrier is a mechanical barrier and root deflector
<br />used to prevent tree roots from damaging hardscapes and landscapes.
<br />Assembled in 24" (609 mm) long modules to create varying lengths for
<br />linear applications, or perimeter surround applications in varying sizes.
<br />A. Materials
<br />1. The contractor shall furnish and install tree root barrier as specified.
<br />The tree root barrier shall be either product #UB 24-2 as
<br />manufactured by DeepRoot° Green Infrastructure, LLC, 530
<br />Washington Street, San Francisco, CA, www,deeproot.com
<br />(800.458.7668).
<br />2. Root barrier shall be recyclable, black, injection molded panels
<br />with 0.80" (2.03 mm) wall thickness in modules 24" (609 mm)
<br />long and 24" (609 mm) deep.
<br />3. Root barrier shall be manufactured with 75% reprocessed
<br />polypropylene with added ultraviolet inhibitors.
<br />4. Root barrier shall be comprised of 24" (60.96 cm) panels. Each
<br />panel shall have no less than four (4) Molded Integral Vertical
<br />Root Directing Ribs of a minimum 0.075" (1.90 mm) thickness,
<br />protruding 1/2" (12.7 mm) at 90° from interior of the barrier
<br />panel, spaced 6" (152.4 mm) apart. (See Details A & D)
<br />5. Root barrier shall have a Double Top Edge consisting of two
<br />parallel, integral, horizontal ribs at the top of the panel at
<br />0.060" (1.52 mm) thickness, 3/8" (9.53 mm) wide and 1/4" (6.35
<br />mm) apart with the lower rib attached to the vertical Root
<br />Directing Ribs (See Detail A).
<br />6. Root barrier shall have a minimum of twelve (12) Anti -Lift
<br />Ground Lock Tabs consisting of integral horizontal ridges of
<br />minimum 0.075" (1.90 mm) thickness in the shape of a segment
<br />of an oblong, the 2" (50.8 mm) chord of the segment joining the
<br />panel wall and the segment, protruding 3/8" (9.53 mm) from
<br />the panel. The twelve ground locks on each panel shall be about
<br />20 F. equally spaced between each of the vertical root directing ribs
<br />(Four (4) between each set of ribs, see Details B & D).

<br />Note: Root barrier is required by the City of Louisville when the tree lawn condition is less than 10' in width.
<br />Root barrier is required for the mature dripline of the tree only, per manufacturer's specification. Mature dripline
<br />of affected trees has been estimated by Landscape Architect, based upon tree type, soil condition, and climate
<br />conditions in Louisville, Colorado.
