A simple measure that ensures you’ll double the life expectancy of your concrete paths around trees.

HOW IT WORKS Under concrete moisture is trapped naturally, this provides a food source for the tree.Tree roots fi nd the food and transport it back to the tree, the root that fi nds the most food grows the biggest. Root Barrier™ Under Path Growth Inhibitor creates a 50mm deep zone under the structure which is outside the pH range that trees like to feed on. Roots in this immediate area will not develop to damage the path. The other roots will fi nd a more suitable food source allowing them to support and feed the plant.

This product is 100% natural with no manufactured chemicals and the same salinity as sea water. The product is stabilised to prevent active components leaching from under the path.DPI tested, certifying the product meets EPA guidelines protecting local environment.Not dangerous to handle in normal circumstances, MSDS available.

USES • Footpaths• Driveways• Pavers

INSTALLATION1. Clear the damaged section, remove existing roots in the vicinity and

prepare the subgrade as normal,2. Pour the dry Under Path Growth Inhibitor on to the exposed subgrade

and spread with a rake at a ratio of 10 Kg per m2 of subgrade.3. Continue to lay the new path as normal.

RESULT 50 mm deep zone immediately below the treated area will have a pH level outside the range required by the tree.

UNDER PATH GROWTH INHIBITOR PRODUCT ASSESSMENT

REPORT SUMMARY 16 Aug. 2010

Plate 1. Photos taken 2 August 2010 of (a) sample location A, under the current footpath and (b) sam-ple location B, adjacent to the footpath under the turf profile.

Root Barrier’s Under Path Growth Inhibitor has undergone preliminary testing through DEEDI (Department of Employment, Economic Development and Innovation). Below is a summary of the report prepared by Matt Roche Acting senior research scientist, Agri-Science Queensland. Objectives To monitor the pH and electrical conductivity/salinity (EC) of the trial site prior toand fol-lowing the application of the root growth inhibitor treatment by the Client. The collected data will be provided to the Client within this, a preliminary report (16 Aug. 2010) and a final report (7 Jun. 2011).

Results DEEDI soil testing Results for testing on 8 June (Prior to placing treatment) and 2 August 2010 (Post treatment) using TPS smartCHEM-LAB meter.

Electrical Conductivity (EC) is a convenient method for measur-ing soil salinity. The bar charts show June soil samples in Black and August samples in Green. The graph below shows that the Under Path Growth Inhibitor did not leach into the surrounding environment.

CD 2010/3 Page 4 of 6Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION

PERSONAL PROTECTION

EYE■ No special equipment for minor exposure i.e. when handling small quantities.• OTHERWISE:• Safety glasses with side shields.• Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A

written policy document, describing the wearing of lens or restrictions on use, should be created for eachworkplace or task. This should include a review of lens absorption and adsorption for the class ofchemicals in use and an account of injury experience. Medical and first-aid personnel should be trained intheir removal and suitable equipment should be readily available. In the event of chemical exposure, begineye irrigation immediately and remove contact lens as soon as practicable. Lens should be removed at thefirst signs of eye redness or irritation - lens should be removed in a clean environment only after workershave washed hands thoroughly. [CDC NIOSH Current Intelligence Bulletin 59].

HANDS/FEET■ No special equipment needed when handling small quantities.OTHERWISE: Wear chemical protective gloves, eg. PVC.

OTHER■ No special equipment needed when handling small quantities.OTHERWISE:• Overalls.• Barrier cream.• Eyewash unit.

Section 11 - TOXICOLOGICAL INFORMATION

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED■ The material has NOT been classified by EC Directives or other classification systems as "harmful byingestion". This is because of the lack of corroborating animal or human evidence. The material may still bedamaging to the health of the individual, following ingestion, especially where pre-existing organ (eg. liver,kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on dosesproducing mortality rather than those producing morbidity (disease, ill-health). Gastrointestinal tractdiscomfort may produce nausea and vomiting. In an occupational setting however, ingestion of insignificantquantities is not thought to be cause for concern.

EYE■ The dust may produce eye discomfort and abrasive eye inflammation.

SKIN■ There is some evidence to suggest that this material can cause inflammation of the skin on contact in somepersons.

INHALED■ Generated dust may be discomforting.

CHRONIC HEALTH EFFECTS■ Long term exposure to high dust concentrations may cause changes in lung function i.e. pneumoconiosis;caused by particles less than 0.5 micron penetrating and remaining in the lung. Prime symptom isbreathlessness; lung shadows show on X-ray.

TOXICITY AND IRRITATION■ unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances.

TOXICITY IRRITATIONOral (Rat) LD50: >2000 mg/kg(calculated)

■ Classification of the preparation and its individual components has drawn on official and authoritative sources as well as independent review by the Chemwatch Classification committee using available literature references.A list of reference resources used to assist the committee may be found at: www.chemwatch.net/references.

■ The (M)SDS is a Hazard Communication tool and should be used to assist in the Risk Assessment. Many factors determine whether the reported Hazards are Risks in the workplace or other settings. Risks may be determined by reference to Exposures Scenarios. Scale of use, frequency of use and current or available engineering controls must be considered.
