Common Types of Tarmac Damage Mostyn
When properly installed, tarmac and asphalt surfaces can deliver decades of reliable service; however, minor defects such as inadequate edging in critical areas, diesel spillage, or poor compaction can result in uneven surfaces, depressions, and deterioration of your driveway in Mostyn.
Prior to commencing any repair work in Mostyn, our tarmac contractors evaluate the root cause of the damage. The most frequent problems we encounter include:
- Surface cracks resulting from weather exposure or ground movement
- Potholes formed by water penetration and freeze-thaw cycles
- Edge deterioration at the boundary where tarmac meets grass or gravel
- Sunken areas caused by inadequate sub-base or excessive loads
- Surface ravelling where the bitumen binder has broken down
How We Repair The Tarmac / Asphalt
Initial Assessment
We begin by inspecting the damaged area to establish whether a patch repair is adequate or if a larger section requires resurfacing. Small isolated defects can typically be patched, while extensive cracking or numerous potholes often suggest that a complete resurface is the more cost-effective long-term option.
Preparation Work
Thorough preparation is critical for a durable repair. We cut out the damaged section with a disc cutter to establish clean, vertical edges. This ensures the repair material doesn’t merely rest on top of compromised tarmac. For potholes, we extract all loose material and inspect the sub-base beneath. If the sub-base has deteriorated, we excavate deeper and compact fresh stone before applying any tarmac.
Applying the Repair Material
We utilize hot bitumen tarmac for the majority of repairs as it provides superior bonding compared to cold-lay products. 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 layers, thoroughly compacting each layer with a vibrating plate or roller, depending on the repair size.
Finishing and Compaction
The final surface is rolled to align with the level and finish of the surrounding area. We intentionally overfill the repair slightly, as the material will settle under the roller. The edges require particular attention—adequate compaction is essential to prevent future deterioration.
When to Consider Full Resurfacing
If your tarmac exhibits numerous damaged areas or the surface exceeds 15-20 years of age, repairing individual spots may prove uneconomical. At Driveways Mostyn, we provide an honest evaluation of whether repairs offer good value or if resurfacing the entire area represents a better solution.
