What’s included?

• 26 x 25KG tubs of UltraCrete IRR 6mm, a permanent cold-lay asphalt for footways, footpaths, cycle tracks, car parks and driveways.
• 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 repair programmes, contractors topping up existing stock and teams that want the complete IRR and SCJ pairing without committing to 52 tubs.

Why use IRR 6mm with SCJ?

SCJ is applied to the vertical edges of the excavation and the substrate before the IRR is placed. It forms the 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 each additional layer, then use it to seal the final joint after compaction.

IRR 6mm 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 programme?

Yes. This offer contains 26 x 25KG tubs of IRR 6mm 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 6mm?

Yes, for a first-time permanent repair SCJ should be applied to the vertical edges and substrate before placing IRR. Re-apply it to the edges before any additional layer and to the final joint after compaction.

What surfaces is IRR 6mm designed for?

IRR 6mm is designed for footways, footpaths, cycle tracks, car parks and driveways. For Type 3 and 4 roads, use IRR 10mm instead.

How quickly can the area be opened?

Once the IRR has been correctly compacted, it is instantly trafficable, subject to the requirements of the site.

Can I use IRR 6mm in the rain?

IRR 6mm can be used in wet conditions when it is placed and compacted correctly. For heavy or persistent rain, UltraCrete Tough Patch Rapid may be the better choice because it is designed for water-curing and higher skid resistance.

What is the difference between 6mm and 10mm?

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

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 6mm 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 6mm and SCJ combination can be used for suitable footway, footpath, cycle-track and other 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 6mm is suitable for many driveway and car-park repairs when the depth and substrate are appropriate. Remove loose material, apply SCJ to the edges and base, place the IRR in suitable layers and compact it thoroughly.

More questions about IRR 6mm tubs

What is the difference between the tub and the bag?

Both contain 25KG of the same IRR 6mm material and once opened, all material should be used. The tub is useful when you need a rigid, stackable format that is easy to move around site. 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 practical for handling and storage, but once opened all material should be used. Plan to complete the repair using the full contents of the tub.

Is Instant Road Repair 6mm a permanent repair?

Yes. When applied correctly, including the use of UltraCrete SCJ to seal the edges and substrate, IRR 6mm provides a first-time permanent reinstatement. It has been HAPAS approved since 2002.

Can I use IRR 6mm on a car park or driveway?

Yes. IRR 6mm is suitable for car parks and driveways as well as footways, footpaths and cycle tracks. For high-stress areas subject to turning or heavy braking, UltraCrete Tough Patch offers greater skid resistance.

When should I use Tough Patch instead of IRR 6mm?

UltraCrete Tough Patch is designed for areas requiring maximum skid resistance and for heavy or persistent rain.

Do I need to use SCJ?

Yes. We recommend SCJ Seal and Tack Spray on all vertical edges and the substrate, and between layers for deeper reinstatements. It creates a bituminous bond and helps improve repair longevity.

Is a part-pallet or full-pallet deal available?

Yes. This page is the 26-tub part-pallet deal with 12 cans of SCJ and free delivery to England & Wales. A larger 52-tub offer is also available.
