What’s included?

• 26 x 25KG tubs of UltraCrete IRR 10mm, a permanent cold-lay asphalt for Type 3 and 4 roads, drives, minor roads and vehicle-trafficked car parks.
• 12 x 750ml cans of SCJ Cold Joint Bitumen Spray, applied to vertical faces and the substrate before and between layers of IRR.
• Free standard delivery to England & Wales.

Why choose the 26-tub deal?

This part-pallet quantity is a useful middle ground between buying individual tubs and ordering a full pallet. It suits smaller road-repair programmes, contractors topping up existing stock and teams that need the complete IRR and SCJ pairing without committing to 52 tubs.

Why use IRR 10mm with SCJ?

SCJ is applied to the vertical edges of the excavation and the substrate before the IRR is placed. It forms a bituminous seal and tack coat that helps prevent water ingress and creates a proper bond between the repair and the surrounding surface. Re-apply it to the edges before additional layers, then use it to seal the final joint after compaction.

IRR 10mm and SCJ bundle FAQs

I’m Cleo, owner of The Paving Experts, with over 25 years in the construction industry working with businesses including Tarmac and Instarmac. 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.

Is this 26-tub offer suitable for a smaller road-repair programme?

Yes. This offer contains 26 x 25KG tubs of IRR 10mm and 12 cans of SCJ, making it a practical part-pallet quantity for smaller programmes, top-up orders and contractors who do not need a full 52-tub pallet.

Do I need to use SCJ with IRR 10mm?

Yes. For a first-time permanent repair, apply SCJ to the vertical edges and substrate before placing IRR, between layers for deeper reinstatements and to the final joint after compaction.

What surfaces is IRR 10mm designed for?

IRR 10mm is designed for Type 3 and 4 roads and vehicle-trafficked surfaces including drives, minor roads and car parks. For footways, footpaths and cycle tracks, IRR 6mm is the correct grade.

How quickly can the area be opened to traffic?

Once correctly compacted, IRR 10mm is instantly trafficable for motor vehicles, subject to the requirements of the site.

Can I use IRR 10mm in the rain?

IRR 10mm is compaction-cured and can be used in light rain. If heavy or persistent rain is forecast, UltraCrete Tough Patch may be the better product because it is water-cured and designed for wet conditions.

When should I use Tough Patch instead of IRR 10mm?

UltraCrete Tough Patch is designed for areas requiring maximum skid resistance, such as turning circles, lorry parks, bus lanes and braking areas, and for heavy or persistent rain.

What is the difference between IRR 10mm and 6mm?

10mm is for Type 3 and 4 roads and other vehicle-trafficked surfaces, with a minimum depth of 30mm. 6mm is for footways, footpaths, cycle tracks, car parks and driveways, with a minimum depth of 15mm.

Why is my IRR firm in the tub?

Apply light pressure to the material in the tub to restore normal consistency. In cold weather, store it somewhere warm overnight before use.

What is the shelf life?

IRR 10mm has a shelf life of 6 months from the date of manufacture in sealed tubs. Once opened, use all the material. Store SCJ cans in a cool, well-ventilated place.

How do I apply SCJ?

Shake the can well and spray directly onto the vertical faces of the excavation and the substrate before placing IRR. Re-apply it before each additional layer and to the final joint after compaction.

How many cans of SCJ are included?

This bundle includes 12 x 750ml cans. The bundle specification is approximately 150 linear metres per can, depending on the thickness applied.

Can utilities contractors use this bundle?

Yes. The IRR 10mm and SCJ combination can be used for suitable road and vehicle-trafficked reinstatement work following utility repairs, duct installation or other openings. Always check the required road category, depth and reinstatement specification before choosing the grade.

Can I use this for a driveway or car-park repair?

IRR 10mm can be suitable for deeper driveway and car-park repairs where the depth and traffic loading call for the 10mm grade. For shallow or lighter-duty repairs, 6mm may be the better specification. Contact us if you want to check a particular repair before ordering.

More questions about IRR 10mm tubs

What is the difference between the tub and the bag?

Both contain 25KG of the same IRR 10mm material and once opened, all material should be used. The tub is preferred by contractors who need a stackable, rigid container that is easy to move around site and between jobs. The bag gives better pallet efficiency, with 56 bags compared with 52 tubs per pallet, and suits larger single repairs or bulk purchasing.

Can I reseal the tub and use it later?

The tub is a practical rigid format for handling and storage, but once opened all material should be used. Plan to use the full contents when you open a tub.

Is Instant Road Repair 10mm a permanent repair?
