Vuba Resin Bound Binder is a two component aliphatic (UV Stable) polyurethane stone encapsulation binder, for use with decorative dried aggregates. 

Vuba Resin Bound Binder has been formulated and produced at our factory in Beverley, East Yorkshire. Our resin binder has been subjected to intensive independent testing, and produced exemplary mechanical property performance. 

A 7.5kg Vuba Binder should be used with our Trade Kits. Suitable for use with aggregates from the Wonders of the World Range (Vehicle Traffic VT and Pedestrian PP), and the Classic Resin Driveways Range. 

Our Resin now comes in two grades, pre-catalyzed and uncatalyzed. The pre-catalyzed resin will have a level of catalyst included which is determined by the average temperature across the county at the time of ordering. For the uncatalyzed resin we would recommend purchasing Accelerex so you can add the catalyst needed for the optimum temperate at the time of application.

7.5kg Mixed with 4 bags of Aggregate to create a Resin Bound Kit which covers 3.5m2 at 18mm depth.

Tear Resistance 18.8
Elgonation at Break 67.2%
Tensile Strength 12.3 MPa

Each 7.5kg Vuba Resin Bound Binder is to be mixed with 100kg of aggregates (4 x 25kg). For areas subject to vehicle traffic you would also need to add a 6.25kg of binding aggregate.

Pedestrian Traffic:
Each kit will cover 4.2m2 at 15mm on average. 

Vehicle Traffic:
Each kit will cover 3.5m2 at 18mm on average. 

Please note different aggregates do vary as a result of particle density and we would recommend to order 10% wastage. 

Sub-Base:
Before application of an Asphalt / Tarmac base, concrete or cellular grid, there should be in place the correct sub-base. This would be a minimum 150mm depth of well compacted Type 3 granular sub-base to SHW clause 805, or 4/40mm, 4/20mm crushed aggregate to BS EN12620 or locally available secondary or recycled aggregates which comply with the above specification blinded with 2/6.3mm graded crushed concrete aggregate to BS EN12620.

Concrete: 
1. Concrete bay proportions should be ideally 1:1 and should not be greater than 3:2, long narrow strips of concrete will crack across the bay width and these cracks are likely to be mirrored in the surfacing. 
2. Open bay joints are likely to cause cracking in the surfacing and formation should be prevented by application of Polycrete repair mortar into the joints. Bays should be linked with steel mesh reinforcement, or if already in place, a surface grade mesh should be embedded in the surface using an epoxy bedding coat. 
3. Ensure that the concrete has a minimum design strength of C35 and that the concrete has a minimum compressive strength of 25N/mm2 before the surface is prepared, in accordance with BS 8500-2:2015. 

Drainage:
Ensure that falls are in place to an adequate drainage system when applying to an impermeable concrete base. Water will flow through the Valtex system and run across the concrete surface.

Asphalt (Bituminous Macadam):
The bitumen binder of asphalt concrete must have a pen value no greater than 100/150, when tested in accordance with EN 1426 Needle Penetration Test. It is advisable to use a harder grade of bitumen when machine application is possible and 70/100 pen (or harder) is preferred.

Bituminous materials with a higher pen value will be too soft and may deform in warm weather. Adequate compaction of the sub-base and base is essential to prevent cracking. A minimum 1 tonne “sit on” roller should be used when possible and the contractor must ensure that the construction is fully restrained at all edges to ensure dimensional stability.

Drainage:
Rainwater will flow through the permeable Valtex Resin Bound System, and through the open grade binder course. An integral drainage system is not required.

Cellular Grid:
We would recommend to use a cellular grid of 40-50mm in depth. The grid should be set on to a well compacted sub-base as laid out above. The cellular grid should then be filled with well compacted 4/10mm graded crushed aggregate to BS EN12620. The in-fill aggregate must be compacted to ensure the profile of the cellular grid is still visible, and capable of bonding to the resin bound system. 

Failure to compact the stones within the grid correctly will result in a slump of the resin bound material through the grid, causing delamination. 

Perimeter Edging:
Protect all edges abutting soft landscaping with brick, steel, timber or concrete to prevent damage to the surfacing. Edgings should be securely fixed to prevent movement. A flexible joint filler should be used at edgings where there is potential for movement to separate the surfacing from the edging.

Concrete Preparation:
Prepare concrete by mechanical means to provide a sound, clean, dry substrate that is free from laitance and suitable for application of the resin bound surfacing. Concrete should be primed prior to application using our Easiprime or Epiprime (and seeded with a 1.4 - 1.8mm quartz).

Asphalt (Bituminous Macadam) Preparation:
Allow the asphalt to oxidise for 7 days prior to application of the Valtex Resin Bound Surface. It is not a requirement to prime asphalt surfaces.

Suitable Mixing Equipment:
Large Pan Forced Action Mixer such as a Soroto 100L. 

Suitable Resin Binder: 
7.5kg Vuba Resin Bound Binder.

Mixing Guidance: 
1. Scrape all of the contents of Vuba Resin Bound Surfacing B component into the larger Resin A component container and mix with a slow speed drill (≤ 450RPM) and MR2 paddle mixer attachment for 60-90 seconds. Overmixing will increase heat generation and reduce working time. 
2. Simultaneously, add 100kg of aggregate to the Large Pan Forced Action Mixer.Followed by addition of the 6.25kg Binding Quartz (for Vehicle Traffic). Do not allow the aggregate to rotate dry for more than 60 seconds. Excessive dry mixing forms dust in the mixer, which will darken the batch, resulting in shading issues throughout the application. 
3. Allow the aggregate to begin mixing and immediately add the mixed resin to the aggregate in the mixer until all the aggregate is evenly coated with resin. Mix for approximately 3-4 minutes. Overmixing will increase heat generation and reduce working time, in addition to shading issues.
4. Using a wheel barrow, discharge the mixed resin and aggregate onto the prepared surface, level and smooth. Ensure to compact to even firm composition.

Application Advice:
1. Finish the surface with a suitable float. Warm sopay water or a cleaning solvent should be used if required to clean trowel before applying a closing finish to the resin bound surface. Close compaction is vital to prevent stone loosening. Most applicators will compact at right angles to how the material was spread out, applying pressure as the trowel is pulled back. 
2. If required for added slip resistance, immediately cast Crushed Glass onto the top surface of the wet resin and aggregate, at the rate of approximately 0.1kg/m2. Ensure even coverage to prevent a patchy appearance.
3. Allow to cure and open to traffic as described in the Curing Time tables above.

Further Guidance:
1. Regularity and consistency of mixing times is essential to prevent shading within your Resin Bound System. Excessive mixing, especially of dry stone, will result in darker shading.
2. Ensure you have all bags required for your project prior to commencement, and ensure you have sufficient material by marking coverage per mix on the surface. It is imperative to not run short of material for a fully seamless finish. You will be provided with a mix instructions sheet with each order.
3. Ensure you have scheduled to apply your resin bound aggregate system during a period of suitable weather for both application and curing time.
4. Contact Vuba for further advice if you are unsure.
