Common Types of Tarmac Damage Chislehurst
When properly installed, tarmac and asphalt surfaces can deliver decades of reliable service; however, minor installation faults—such as inadequate edging in critical areas, diesel spillages, or poor compaction—can result in dips, uneven surfaces, and deterioration of your driveway in Chislehurst.
Prior to commencing any repair work in Chislehurst, our tarmac contractors evaluate the underlying cause of the damage. The most frequent issues we encounter include:
- Surface cracking resulting from weathering or ground movement
- Potholes developing from water penetration and freeze-thaw cycles
- Edge breakdown where the tarmac borders grass or gravel
- Sunken areas caused by inadequate sub-base or excessive loads
- Surface ravelling where the bitumen binding material has broken down
How We Repair The Tarmac / Asphalt
Initial Assessment
Our process begins with a thorough examination of the damaged area to establish whether a targeted patch repair is adequate or if resurfacing a larger section is necessary. Isolated defects can typically be patched effectively, while extensive cracking or numerous potholes generally suggest that complete resurfacing represents the most cost-effective long-term approach.
Preparation Work
Thorough preparation forms the foundation of any durable repair. We use a disc cutter to remove the damaged section, creating clean, vertical edges. This ensures the repair material integrates properly rather than merely sitting atop compromised tarmac. When addressing potholes, we extract all loose material and inspect the sub-base beneath. Should the sub-base prove inadequate, we excavate deeper, install and compact fresh stone aggregate before applying any tarmac.
Applying the Repair Material
Our repairs utilize hot bitumen tarmac, which provides superior bonding compared to cold-lay alternatives. The repair area receives a tack coat of bitumen emulsion to enhance adhesion between the new material and the existing surface. We then apply the tarmac in successive layers, thoroughly compacting each one using a vibrating plate or roller, selected according to the repair’s dimensions.
Finishing and Compaction
The final surface undergoes rolling to align with the level and texture of the surrounding area. We intentionally overfill the repair slightly, accounting for material settlement during the compaction process. Special attention is paid to the edges—adequate compaction in these areas prevents future breakage and separation.
When to Consider Full Resurfacing
Should your tarmac display numerous damaged areas or the surface exceed 15-20 years in age, repairing individual spots may prove uneconomical. At Driveways Chislehurst, we provide candid assessments regarding whether repairs offer genuine value or if resurfacing the complete area represents the superior option.
