This is a 25kg bag of washed and dried aggregates that can be used in the following ways:
Just Aggregate - You can buy this aggregate as part of a custom 4 Bag Trade Kit, or to top up your existing aggregate stock to make up a blend. Each bag is 25kg in size.
1m2 Resin Bound Resin Kit - You could add 1.75kg 1m2 Vuba Resin Bound Binder to your aggregate, and you have a single ready made Resin Bound Kit which will cover approximately 1m2 on to a hard surface at 15mm thick.
Easihold - This is our revolutionary loose stone binder. You can mix the aggregate with 1.25 litres of Easihold you then have a kit which can be laid on to almost any surface at 20mm thick and cover 0.75m2, and be used as a path or patio surface. Alternatively you can evenly spread the aggregate on a hard surface then pour or spray the Easihold over the surface to bind the stones together.
25kg of aggregate
1m2 Resin Bound Resin Kit
1.75kg Resin (7.5% Resin : Aggregate Ratio - Very High)
= 26.75kg Kit
Each kit will cover approximately 1m2 at the advised 15mm thickness.
4 x 25kg Aggregate
5 Litres of Easihold Binder
= 105kg Kit
Each 105kg Stone Bundle kit will cover 3m2 at the advised 20mm thickness.
When considering your base, you should think about 'is this base strong enough for my intended purpose? The base is of less importance with Easihold than Resin Bound, as Easihold is also a wearing course.
We would recommend the ideal substrate to be a compacted hardcore, or other stabilised surface should as concrete, existing paving, macadam etc. We would advise the inclusion of a permeable membrane beneath the system to prevent growth of weeds.
1m2 Resin Bound Resin Kit
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.
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.
Ensure that falls are in place to an adequate drainage system when applying to an impermeable concrete base. Water will flow through the Vuba resin bound 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.
Rainwater will flow through the permeable Vuba Resin Bound System, and through the open grade binder course. An integral drainage system is not required.
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.
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.
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 Vuba Resin Bound Surface. It is not a requirement to prime asphalt surfaces.
Use as a decorative stone or alternatively within a Vuba Resin Bound Trade Kit. A Resin Bound Trade Kit is typically made up of the following:
4 x 25kg Aggregate
1 x 5kg Binder Aggregate
1 x 7.5kg UV Stable Resin
These Trade Kits are available here. You can purchase this aggregate to create your custom kit.
Vuba 1m2 Resin Bound Kit:
1. Scrape all of the contents of the Hardener B and component Resin A into a suitable bucket and mix with a slow speed drill (≤ 450RPM) and MR2 paddle mixer attachment for 60-90 seconds.
2. Slowly add the 25kg Aggregate Kit whilst mixing, and mix for approximately 2 minutes until the resin has fully encapsulated the stone.
3. Finish the surface with a suitable float. 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.
4. 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.
5. Allow to to reach full cure after approximately 24-72 hours temperature dependent.
1. Ensure the base is suitable as per guidance above.
2. Pour the aggregate and Easihold into a 30 litre bucket at the ratio of 1.25 Litres of Easihold to 25kg of Aggregate.
3. Shake / Mix the Easihold resin liquid with the aggregate until the aggregate is fully coated.
4. Pour the Stone Mix kit out at 20-25mm thickness and allow to dry for 48 hours.
5. Do not lay in inclement weather because liquid Easihold can be washed away.
