About Slurry Seal
A slurry seal is a surface treatment, not a rebuild: a mix of bitumen emulsion, fine aggregate, water and filler, spread over an existing tar or asphalt surface in a layer a few millimetres thick and left to cure before traffic goes back on it. It suits a surface that is greying, drying out or losing its skid resistance but has not yet cracked through to the base underneath — rather than milling out and relaying the area, a slurry seal closes the surface back up, restores a uniform black finish, and buys years before a full resurface is needed. We apply it on private roads, complex and estate access ways, business parking areas and industrial yards across Germiston, the East Rand and Johannesburg, using our own crew and equipment rather than a subcontracted gang.
What's Included
- Full assessment checks traffic loading and drainage
- Confirms if the problem is surface-only or deeper
- Surface swept clean of loose material, dust and debris
- Isolated potholes and breaks patched before slurry
- Oil staining and vegetation in joints dealt with first
- Bitumen emulsion, fine aggregate, water and filler mix
- Applied with a squeegee box in one continuous pass
- Cured and reopened on a schedule around your access
Our Process
- 1
Assess the Surface
We walk the surface before pricing it — checking whether the problem is confined to the top layer or has reached the base, plus drainage, falls and traffic loading. If the base has already failed, we say so rather than sell a treatment that won't hold.
- 2
Prepare and Clean
The surface is swept clean of loose material, dust and debris. Isolated potholes and breaks are patched first, and oil staining or vegetation in joints is dealt with, so the slurry isn't laid over a defect that stops it bonding.
- 3
Mix and Apply
The slurry — bitumen emulsion, graded fine aggregate, water and filler — is spread with a squeegee box in a controlled, even layer a few millimetres thick, across the full width in one continuous pass.
- 4
Cure and Reopen
The slurry cures and sets before we reopen the area to traffic. Exact timing depends on weather, temperature and the mix used — we plan the work around your access needs rather than ours.

Slurry Seal FAQ
What is a slurry seal?
A slurry seal is a thin surface treatment applied over an existing tar or asphalt surface, made from bitumen emulsion, fine aggregate, water and filler. It's spread evenly with a squeegee box in a layer a few millimetres thick, then left to cure before traffic returns. It's not a structural repair — it renews and protects a surface that's still sound underneath but has started to grey, dry out or lose skid resistance on top.
What is the difference between a slurry seal and a chip and spray seal?
Chip and spray applies a bituminous binder followed by a layer of stone chip, giving a rougher, more textured surface suited to lower-speed roads and industrial yards. A slurry seal uses fine aggregate instead, giving a smoother, quieter finish suited to estate roads, driveways and parking areas. Both close the surface against water — the choice comes down to the traffic the surface carries and the finish you want.
What is the difference between a slurry seal and a cape seal?
A cape seal combines both treatments: a chip and spray layer laid first for strength, capped with a slurry seal on top for a smooth, closed finish. It costs more than a slurry seal alone but holds up to heavier, more consistent traffic. A slurry seal alone suits lighter, steadier traffic such as estate roads and parking areas.
How long does a slurry seal last?
A properly applied slurry seal, laid on a sound base at the right point in the surface's life, typically extends its useful life by several years before the same treatment or a full resurface is needed again. How long it actually holds depends on traffic, drainage and the condition of the base underneath, which is why we assess your specific surface rather than quote a blanket figure.
Will a slurry seal fix cracks or potholes?
It bridges fine, hairline surface cracking, but it isn't a fix for potholes or cracks that have already reached the base. We patch potholes and deal with structural breaks before the slurry goes down — sealing over an unrepaired defect just traps the problem underneath a new surface. If most of the surface has failed structurally, pothole and patch repairs or a full resurface is the correct starting point instead.
