Common Types of Tarmac Damage Tonbridge
When properly installed, tarmac and asphalt surfaces can deliver decades of reliable service; however, minor issues such as inadequate edging in critical areas, diesel spillage damage, or poor compaction can result in uneven surfaces, depressions, and deterioration of your driveway in Tonbridge.
Prior to commencing any repair work in Tonbridge, our tarmac contractors evaluate the underlying cause of the damage. The most frequently encountered problems include:
- Surface cracks resulting from weather exposure or ground settlement
- Potholes formed by water penetration and freeze-thaw action
- Edge breakdown where the tarmac borders grass or gravel areas
- Sunken areas arising from inadequate subbase or excessive weight
- Surface ravelling where the bitumen binding material has broken down
How We Repair The Tarmac / Asphalt
Initial Assessment
Our process begins with a thorough inspection of the damaged area to establish whether a localised patch repair is appropriate or if resurfacing a larger section is required. Individual isolated defects typically respond well to patching, 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 resting on compromised tarmac. When addressing potholes, we extract all loose material and inspect the subbase beneath. Should the subbase prove inadequate, we excavate deeper and compact fresh aggregate before applying any tarmac.
Applying the Repair Material
Hot bitumen tarmac is our material of choice for most repairs due to its superior bonding properties compared to cold-lay alternatives. We prime the repair area with a tack coat of bitumen emulsion to ensure optimal adhesion between the new material and the existing surface. The tarmac is then applied in layers, with each layer receiving thorough compaction using a vibrating plate or roller, selected according to the repair size.
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 at first, accounting for the material settling under roller compaction. Special attention is paid to the edges—adequate compaction in these areas prevents future deterioration and breakage.
When to Consider Full Resurfacing
When your tarmac exhibits numerous damaged areas or the surface has exceeded 15-20 years of age, repairing individual spots may prove uneconomical. At Driveways Tonbridge, we provide transparent guidance on whether repairs deliver genuine value or if resurfacing the complete area represents the better investment.
