ROAD REPAIR GAUTENG
Pothole Repairs, Base Corrections & Thermal Bond Infrared
Tarco Mzansi delivers durable road repair solutions across Pretoria, Johannesburg and the wider Gauteng area. We specialise in pothole repairs, base corrections and surface texture repairs, using advanced thermal bond infrared technology wherever possible. Our approach focuses on fixing the underlying cause of damage so repairs last, rather than simply covering symptoms.
We create strong, seamless joints that resist reopening and water ingress — a common failure point with traditional saw-cut patching. Whether the damage is superficial or requires deeper structural work, every repair is completed to a high standard with proper compaction so the finished surface sits level with the surrounding asphalt and does not sag under traffic.
THERMAL BOND INFRARED REPAIRS
For Surface & Texture Issues
For superficial damage and surface texture repairs, we use thermal bond technology with infrared heater boxes. This method is Agrément (CSIR) certified and avoids the cold joints created by saw cutting.
Because the surrounding asphalt is thermally heated, the repair bonds monolithically with the old surface. There is no saw-cut joint that can open over time. The result is a tighter, more durable repair with better long-term performance than conventional cold-patch or cut-and-fill methods.
THE THERMAL BOND PROCESS
Seamless Infrared Repair Process
STEP 01
Rejuvenate
Apply a rejuvenator to restore the damaged surface asphalt.
STEP 02
Infrared Heating
Place infrared heater boxes over the area and heat slowly and evenly to approximately 140°C.
STEP 03
Add Virgin Asphalt
Add virgin asphalt material as required.
STEP 04
Scarify & Blend
Scarify and blend the heated material thoroughly.
STEP 05
Recompact
Recompact to achieve full density and a level finish that matches the existing road.
STEP 06
Seal the Interface
Where needed, apply a small amount of sealer at the interface to further prevent water ingress.
FULL-DEPTH POTHOLE REPAIRS
Repairs With Base Corrections
When damage extends into the base or when structural correction is required, we follow a full-depth process designed for long-term stability.
This combination of proper base preparation, textured vertical faces, tack coating and thermal bonding produces a repair that integrates with the existing road rather than sitting as a separate patch that can fail at the edges.
THE FULL-DEPTH PROCESS
Structural Repair, Step by Step
STEP 01
Mill Out
Mill out the existing asphalt to create a clean, rough-textured vertical interface joint.
STEP 02
Rip & Recompact the Base
Rip and recompact the base layer using in-situ material blended with imported G5 or G1 material (selected according to specification and site conditions).
STEP 03
Repair From the Roadbed Up
Where deeper failure is present, we repair from the roadbed and sub-base upward before placing the base and asphalt layers.
STEP 04
Prime & Tack Coat
Apply prime and tack coat, including to the vertical edges of the repair.
STEP 05
Thermal Interface Bond
Thermally heat the interface joint so the new asphalt bonds monolithically with the existing pavement.
STEP 06
Compact Thoroughly
Compact thoroughly so the repair remains level with the surrounding surface and does not settle under traffic.
WHY OUR METHOD PERFORMS BETTER
Repairs That Stay in Place
- Thermal bond technology creates a monolithic joint instead of a cold saw-cut joint that opens under traffic and weather.
- Proper base correction addresses the root cause of many recurring potholes.
- Thorough compaction ensures the repair stays level and does not dish or sag.
- Reduced risk of water ingress at the joint extends the life of the repair.
- Suitable for estates, business parks, commercial properties, parking areas and private roads throughout Gauteng.
We assess the true cause of the damage before recommending a repair method. Thermal bond infrared repairs are used wherever the asphalt layer is the primary issue; full-depth milling, base correction and thermal interface bonding are used when structural work is needed. The goal is the same in both cases: a durable repair that stays in place.
