Installation Instructions
BIOBARRIER® Installation instructions for both Root Control and Weed Control
Tree Root Control Installation Guidelines
Before you start
Contact your utility company prior to trenching if you suspect service lines are present. Consult a professional arborist if root rimming is required.
Follow all EPA label instructions located on the box and yellow packaging sleeve when installing product. Additional instructions in box.
Important Notes
BIOBARRIER® should be installed on the side of the trench opposite the root source.
Install and cover BIOBARRIER® as soon as possible (within 12 hours) after opening sealed yellow bag; high temperatures and direct sunlight can reduce effective product life.
Store out of direct sunlight.
Installing the product
Cut a trench a minimum of 100mm wide and at least equal to the length of mature tree canopy plus 3 meters, centred on the root source and adjacent to the structure using clean-cutting trench digging equipment . For protected trees the services of a certified arborist will be required.
Cut all roots back flush to trench walls on both sides of trench manually with a sharp saw or similar.
Smooth soil surface to desired FINAL GRADE LEVEL on side of trench opposite root source
CAREFULLY open yellow bag of BIOBARRIER® on one end to prevent damage. Use yellow bag to store any unused product.
Roll out BIOBARRIER® and trim to proper length with a pair of scissors. Place excess material back in yellow bag and seal tightly with spare ties provided.
Beginning at one end of the trench, hold product in place at finished grade level on the side of the trench adjacent to the hardscape (opposite root source) and stake in position using pins provided. Use Caution when handling installation pins - they are sharp.
Pins should penetrate fabric between the nodules -10mm from the top edge of the fabric and at -45 degree angle to the trench wall. Enough pins are provided to secure fabric every 600mm. The top edge of the product must be at finished grade level for the entire length of the installation.
Backfill and tamp firmly to eliminate soil settling. Wet soil, if necessary, to ensure proper soil compaction.
NOTE: These guidelines are for a typical urban sidewalk application. Other installations such as property lines, building foundations, retaining walls, ornamental beds, septic systems, storm drains, etc. may require minor procedural adjustments.

GENERAL INSTALLATION GUIDELINES
Weed and Root Control
THESE GENERAL GUIDELINES MUST BE FOLLOWED IN ALL BIOBARRIER® INSTALLATIONS. REFER TO INDEX OF SPECIFIC INSTRUCTIONS.
Review site-specific design plan with a certified local arborist for all applications specifically for depth of BIOBARRIER® required and ESPECIALLY IF ROOT TRIMMING IS REQUIRED! Many tree species have varying root depths.
Contact utility companies prior to digging or trenching in the event service lines are present.
Wear chemical resistant gloves when handling BIOBARRIER® to prevent staining.
See product label and Material Safety Data Sheet (MSDS) for further information.
Do not allow gaps in fabric during installation or backfilling
When joining two pieces of BIOBARRIER®, be sure they do not become separated at any point. Seaming can be accomplished by using construction adhesive and/or overlapping. If the latter is used, seams should be overlapped at least 75mm (or 2 nodule widths). Sod pins may also be used for seams, but make sure there are no gaps.
BIOBARRIER® should not be left exposed to surface water or sunlight for more than 12 hours since high temperatures and sunlight reduce effective life of product.
BIOBARRIER® products are for non-food uses only.
BIOBARRIER® stops roots within ~25mm of a nodule. Proper placement is very important; It is only effective where it is!
