How to prepare surfaces for QC10 F
All surfaces should be free from oil, grease, dust or any other visible contaminants.- 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. Good concrete practice should always be observed to enable the mix to be placed into position within 4 minutes.
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
- Pour mixed QC10 F into place (if required lightly trowel to ensure good contact with edges), 60mm below the required surface.
- 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.
- Clean any mixing equipment with water immediately after use.

UltraCrete QC10 F Rapid Set Flowable Concrete: Pallet Deal — 56 x 25KG Bags, Free Delivery
UltraCrete QC10 F is a HAPAS approved, fibre-modified, rapid set flowable concrete used daily by highways contractors, utilities and telecoms subcontractors, specialist groundworks contractors and local authorities across the UK. It achieves 20N/mm² compressive strength in just 90 minutes, sets in 10–20 minutes and can be opened to traffic in 90 minutes — making it the go-to flowable concrete for backfilling around manhole frames and gullies, ironwork reinstatement, surface and trench repairs, and heavy-duty post installation. Its flowable consistency means it pours into place around complex ironwork and post bases without the need for tamping, making it faster and easier to place in confined excavations.
If your team uses QC10 F regularly, buying by the pallet makes good sense. Our pallet price of 56 x 25KG bags represents a 4% saving compared to buying individual bags, and free delivery is included on top. Need more than a pallet? Give us a call — we’re happy to talk through bulk pricing.
We’re a small, family-run business — I’m Cleo, the owner, with over 25 years in the construction industry working with businesses including Tarmac and Instarmac. QC10 F is a product we know well and recommend with confidence. If you’ve got a question about whether it’s right for your application, just give us a ring.
Need individual bags rather than a full pallet? QC10 F is available as a single 25KG bag. For thick-section repairs and haunching where a stiffer mix is preferred, see QC10 and its pallet deal. Note: patching and surface repairs require use of Ultrascape Pro Prime Slurry Primer prior to application. Always follow the current technical datasheet and your site specification.

UltraCrete QC10 F Rapid Set Flowable Concrete: Pallet Deal — 56 x 25KG Bags, Free Delivery
UltraCrete QC10 F is a HAPAS approved, fibre-modified, rapid set flowable concrete used daily by highways contractors, utilities and telecoms subcontractors, specialist groundworks contractors and local authorities across the UK. It achieves 20N/mm² compressive strength in just 90 minutes, sets in 10–20 minutes and can be opened to traffic in 90 minutes — making it the go-to flowable concrete for backfilling around manhole frames and gullies, ironwork reinstatement, surface and trench repairs, and heavy-duty post installation. Its flowable consistency means it pours into place around complex ironwork and post bases without the need for tamping, making it faster and easier to place in confined excavations.
If your team uses QC10 F regularly, buying by the pallet makes good sense. Our pallet price of 56 x 25KG bags represents a 4% saving compared to buying individual bags, and free delivery is included on top. Need more than a pallet? Give us a call — we’re happy to talk through bulk pricing.
We’re a small, family-run business — I’m Cleo, the owner, with over 25 years in the construction industry working with businesses including Tarmac and Instarmac. QC10 F is a product we know well and recommend with confidence. If you’ve got a question about whether it’s right for your application, just give us a ring.
Need individual bags rather than a full pallet? QC10 F is available as a single 25KG bag. For thick-section repairs and haunching where a stiffer mix is preferred, see QC10 and its pallet deal. Note: patching and surface repairs require use of Ultrascape Pro Prime Slurry Primer prior to application. Always follow the current technical datasheet and your site specification.

I work alongside a small team of incredibly knowledgeable and caring individuals who share the same passion for getting it right. The FAQ answers below come from the questions we’re asked every single day.
How much do I save buying a pallet of QC10 F?
Our pallet price of 56 bags works out at a 4% saving compared to buying individual bags, and free delivery is included on top. If you need more than a pallet, call us on 0330 122 1025 and we’ll talk through bulk pricing.
Is delivery free on the pallet?
Yes — free delivery is included on all pallet orders. Lead times can vary so if you’re working to a programme, give us a call and we’ll give you an accurate estimate.
What is UltraCrete QC10 F?
QC10 F is a HAPAS approved, fibre-modified rapid set flowable concrete designed for backfilling around manhole frames and gullies, ironwork reinstatement, surface repairs and heavy-duty post installation. It achieves 20N/mm² compressive strength in 90 minutes and can be opened to traffic in 90 minutes.
How quickly does QC10 F set?
QC10 F has a set time of approximately 10–20 minutes, with a workability window of around 5–10 minutes. Mix only what you can place within 4 minutes and never remix or add water once mixing is complete.
How long before QC10 F can be trafficked?
QC10 F can be opened to traffic after approximately 90 minutes.
What depth can QC10 F be applied at?
QC10 F is suitable for applications from 30mm to 500mm in one pass.
What is the difference between QC10 F and QC10?
QC10 F is the flowable, fibre-modified version — it pours into place around manhole frames, gullies and post bases without tamping and is open to traffic in 90 minutes. QC10 is a stiffer rapid strength concrete for thick-section repairs, haunching and ironwork backfilling, open to traffic in 2 hours.
Can QC10 F be used for electric gate posts?
Yes — its flowable consistency makes it easy to pour around gate post bases without tamping, and it achieves 20N/mm² in 90 minutes, so you can commission and test gate movement significantly sooner than with conventional concrete.
Can I order single bags rather than a full pallet?
Yes — QC10 F is available as a single 25KG bag if you don’t need a full pallet.
Do you offer bulk discounts beyond pallet quantities?
Yes — call us on 0330 122 1025 and we’ll see what we can do. We’d rather have that conversation than leave you guessing.

How to prepare surfaces for QC10 F
All surfaces should be free from oil, grease, dust or any other visible contaminants.- 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. Good concrete practice should always be observed to enable the mix to be placed into position within 4 minutes.
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
- Pour mixed QC10 F into place (if required lightly trowel to ensure good contact with edges), 60mm below the required surface.
- 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.
- Clean any mixing equipment with water immediately after use.
