RonaDeck Eco Tree Pit is a resin bound natural aggregate finish surround for planted trees in public and private areas. Surrounding the tree in a solid yet semi- flexible construction allows the tree to grow, prevents a build up of litter and removes a storage or hiding place for hazardous items such as syringes and needles.

The RonaDeck Eco Tree Pit comprises a two component polyurethane resin and a range of selected rounded attractive aggregates. The design of this resin bound aggregate system provides a surface which is attractive, highly porous and able to receive light foot traffic.

Its porosity allows water to flow through a 6-10mm aggregate system at the rate of >850 litres/m²/minute. The flow rate may be reduced when using a smaller or more angular aggregate.

UV Stable Resin

RonaDeck Eco Tree Pit resin is UV resistant and will not yellow on exposure to UV light. This is a more attractive option than other types of resin which can yellow and degrade, dramatically altering the appearance of the finished surface.

Application Conditions

The working time and pot life of the resin is affected by material, ambient and substrate temperature. At low temperatures pot life is longer, the material will take longer to cure and the time at which it can be trafficked will be delayed. At higher temperatures pot life, working time and trafficking time is shorter. Typically material can be applied between 5℃ and 25℃.

Do not apply materials at higher temperatures as the pot life of the mixed resin will be so short that it cannot be properly mixed, applied and finished. Similarly do not apply materials if temperatures are so low that the resins are either too viscous to mix or so slow to cure that the applied material could become damaged before it has fully cured.

Instructions for Use

1. Only use clean, kiln-dried, well graded aggregates which are suitable for this use
2. The mixing station must be dry, to avoid entrapment of moisture in the aggregate. Even a small amount of moisture in the aggregate will cause foaming of the resin. Do not apply during rainfall or when rain is expected during the initial curing period
3. Soil to be well compacted and above the level of the root ball
4. Lay minimum 100mm depth of 20mm loose shingle or MOT Type 3 aggregate and compact. Form a rising funnel of aggregate around the tree trunk and apply a minimum 40mm thickness of RonaDeck Eco Tree Pit to the compacted aggregate
5. Where required, form a solid perimeter using timber, kerbing, blocks or similar to create a permanent and secure edging for the loose gravel base and the RonaDeck Eco Tree Pit
6. Place RonaDeck Eco Tree Pit Aggregate into a clean, dry, forced action mixer. When using 6kg resin packs, it is important to mix all the resin with the required amount of aggregate (107kg), this will require a forced action mixer of at least 120 litre capacity, Baron M200 or similar
7. Scrape all the contents of the smaller resin container into the larger one and mix the two components of RonaDeck Eco Tree Pit Resin, using a slow speed drill (≤ 450RPM) and MR2 paddle mixer attachment for 2 minutes. Overmixing will increase heat generation and reduce working time
8. Immediately add the mixed resin to the aggregate in the mixer. Mix the aggregate and resin together until all the aggregate is evenly coated with resin. Mix for approximately 3-4 minutes. Overmixing will increase heat generation and reduce working time
9. Discharge the mixed resin and aggregate onto the prepared surface, compact, level and smooth with a steel float. Avoid excessive compaction as this will reduce porosity
10. Leave sufficient space around the trunk to allow for movement and growth.
11. To provide a more slip-resistant and matt appearance finish, immediately cast RonaDeck TP Fine Aggregate into the top surface of the wet resin and aggregate at approximately 0.1kg/m². Scatter evenly to avoid a patchy appearance
12. Allow to cure. Protect from heavy rain for 1 - 2 hours at 20℃ and open to traffic after 4 hours at 20°C

Adding Slip Resistance To Existing Tree Pit Surfaces

Existing Tree Pit surfaces can be made more slip-resistant as follows:

1. Remove moss, algae and debris. Ensure that the surface is suitably clean, sound, stable and that the surface and underlying resin is dry; run through of resin to damp materials may cause foaming
2. Apply one coat of RonaDeck Resin Bonded Seal Coat UV by roller or airless spray at an approximate coverage rate of 4-5m² per litre
3. Scatter RonaDeck TP Fine Aggregate at 0.1kg per m² onto the wet resin
4. Allow to cure for 2 hours at 20ºC and protect against moisture
5. Remove any unbonded aggregate by vacuum cleaning
6. Refer to RonaDeck Resin Bonded Seal Coat UV data sheet

Shelf Life and Storage

Shelf life of RonaDeck Eco Tree Pit Resin is 6 months, aggregates have an unlimited shelf life when kept in warm, dry, well ventilated conditions. Store all materials in clean, dry, frost free warehouse conditions between 10°C and 25°C. Protect from sunlight.
