Ultracrete QC10 F: Rapid Set Flowable Concrete

Ultracrete QC10 F is a rapid setting, fibre modified, specifically formulated two-part polymer concrete, ideal for backfilling around manhole frames and gullies, which can also be used for surface cracks & repairs.

QC10 F has been HAPAS approved since 2005 and can be opened to traffic in just 90 minutes.

Features and benefits of QC10 F

  • Contains special cements and graded aggregate
  • Simply add water on site to form a high strength concrete
  • Suitable for applications from 30mm – 500mm in one pass.
  • Shrinkage compensated
  • Approved for use on the London Underground and Overground
  • Size: 25kg plastic bag
  • NBS Plus registered for ease of specification

Please note that patching and surface repairs will require the use of Ultrascape Pro Prime Slurry Primer prior to product application. Please click the link if you’d like to add any bags of Pro Prime to your order! Thank you.

Technical information

  • Workability: 5 – 10 minutes
  • Set time: 10 – 20 minutes
  • Depth: 30mm – 500mm
  • 20N/mm² compressive strength after 90 minutes
  • Ideally do not use when temperatures are below 0°C or above 30°C. For use in temperatures outside this range please contact us for advice.

How to prepare surfaces for QC10 F

All surfaces should be free from oil, grease, dust or any other visible contaminants.

  1. Remove all loose particles and work on a sound substrate.
  2. Pre-soak the area with clean water prior to application to aid bond.
  3. Remove ponded water before applying the product. Good concrete practice should always be observed to enable the mix to be placed into position within 4 minutes.

If you are patching with QC10 F, you will need to use Ultrascape Pro Prime Slurry Primer prior to applying QC10 F. Pre-soak the substrate and apply the primer as per the instructions on its packaging. On large scale areas, only pre-soaking will be required.

How to mix QC10 F Rapid Set Flowable Concrete

  • 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.
  • Formulated to be mixed to a smooth flowable consistency.
  • It is advisable to add a maximum of 2 litres of water initially, mix and if required, add up to a further 0.25 litres.
  • It is essential that this product not be over-watered. The addition of excessive water will result in slower strength gain, reduced final compressive strength and the possibility of shrinkage cracking.
  • Sand/aggregate contains moisture and the volume of water required will vary depending on the moisture content of the aggregate.
  • Mix only enough material to apply within 4 minutes.
  • Never remix or add water.
  • If the product needs to be applied to walls then the water content can be reduced to obtain a stiffer consistency.

How to apply QC10 F Rapid Set Flowable Concrete

  1. Pour mixed QC10 F into place (if required lightly trowel to ensure good contact with edges), 60mm below the required surface.
  2. Once the material has reached an initial set, all horizontal surfaces of the reinstatement, including the ironwork, should be sprayed with Ultracrete SCJ. This will prevent the ingress of water into the reinstatement and promote a good bond. Ensure all vertical substrates are fully covered.
  3. Clean any mixing equipment with water immediately after use.
