We live quite far out, and I honestly wasn’t sure if anyone would take on our project. But StimTar not only offered a same-day quote, they were on-site two days later with a full crew! The work was spotless, and the team was professional from start to finish.

Elmarie D., Calvinia, Northern Cape

I’m very particular about the companies I work with, , I read every review and ask a million questions. From the first call, StimTar made me feel like I was in good hands. The lady who helped me was patient, answered everything, and even sent me a quote the same day. I thought, ‘Wow, these people actually care.’

The team arrived early, worked so neatly, and even swept up when they were done like they were working on their own home. Our driveway looks beautiful now, and honestly, I wish more companies operated like this

Nisha G., Laudium

I was skeptical at first — I’ve had bad luck with contractors in the past. But the StimTar team impressed me right away. They arrived exactly when they said they would, got the quote to me in hours, and had the whole school driveway done in just a weekend. Our staff and parents are thrilled!

Mr. T. Mthembu, Pietermaritzburg

We needed tar surfacing for a complex parking lot, and StimTar was by far the most professional company we contacted. Uniformed workers, clean equipment, and constant communication plus they handled site access and prep like pros. Really felt like I was in good hands

FAQs – Frequently Asked Questions About Tar Surfaces

Is tar the same as asphalt?

Not exactly. While both use bitumen as a binder, “tar” often refers to surface treatments or cold mix applications, whereas asphalt typically uses a hot mix. Both are durable, but application methods and costs differ slightly.

How long does a tar road last?

A well-constructed tar road can last 10 to 20 years or more, depending on traffic volume, sub-base quality, and climate conditions. Regular maintenance can extend its lifespan significantly.

Is tar better than paving or concrete?

Yes, in many situations. Tar roads are:

  • Cheaper to install than concrete

  • Faster to lay than paving

  • More flexible under heavy traffic
    However, concrete may outperform tar in extremely heavy-load areas.

Can I lay tar over existing paving or gravel?

Yes, but only if the surface underneath is stable and compacted. We assess each site to determine the best method and ensure a durable result.

Can tar roads handle heavy vehicles like trucks or buses?

Absolutely. Tar roads—especially when properly constructed with compacted layers—are built to withstand high traffic and heavy loads.

Is tar suitable for hot or rainy weather?

Yes. Tar is highly weather-resistant and ideal for South Africa’s diverse climate. We use high-quality materials that resist water, heat, and UV damage.

Will a tar road crack or fade over time?

With proper maintenance, tar roads resist cracking. However, extreme wear, sun exposure, or poor drainage can cause fading or minor cracks—both of which can be repaired easily.

What is the process of building a tar road?

It includes:

  1. Site clearing and grading

  2. Sub-base and base layer preparation

  3. Application of bitumen binder

  4. Tar surfacing

  5. Rolling and compaction

  6. Finishing and quality checks

Can I get a quote for a tar road project?

Yes! We offer free, fast quotes for all types of projects—from private driveways to major roads. Request a Quote Here

Do you offer tar road services nationwide?

Yes, we operate across all provinces in South Africa, including major cities and rural areas. No project is too big or small.
