How to prepare surfaces for QC10
All surfaces should be free from oil, grease, dust or any other visible contaminants before application.- Remove all loose particles and work on a sound substrate.
- Pre-soak the area with clean water prior to application to aid bond.
- Remove ponded water before applying the product).
How to mix QC10 Rapid Strength Concrete
- QC10 can be mixed mechanically or by hand.
- If by hand, ensure that the mixing is vigorous.
- Mix the inner bag containing the cement with the sand/aggregate.
- Add approximately 1 litre of water and mix thoroughly.
- Then, if required, add sufficient additional water until the required consistency is achieved to a maximum of 2 litres.
How to apply QC10 Rapid Strength Concrete
In conjunction with the HAPAS Approved UltraCrete Manhole Reinstatement System:- QC10 should be applied with a float 40mm below the required surface, then compacted to ensure no voids are evident. The final surface should be rough floated to achieve a level surface.
- Once the material has reached an initial set all vertical edges of the reinstatement, including the ironwork, should be sprayed with UltraCrete SCJ. This will prevent the ingress of water into the reinstatement.
- Ensure all vertical substrates are fully covered.
- Apply material over pre-soaked area within 4 minutes of mixing.
- Firm well into position by tamping or using a float.
- Clean any mixing equipment with water immediately after use.
