Can You Resurface Over Existing Tarmac?
Introduction
If your tarmac driveway is looking a little tired, worn, or patchy—but not completely beyond saving—you may be wondering whether resurfacing is a viable alternative to digging everything up and starting from scratch. The good news? In many cases, resurfacing over existing tarmac is entirely possible, and can be both efficient and cost-effective.
At Stowmarket Driveway Services, we’ve helped homeowners and businesses across Stowmarket and Suffolk restore driveways to a like-new finish without the expense of a full replacement. However, whether resurfacing is suitable for your tarmac surface depends on a few critical factors. Let’s explore when resurfacing works, what to watch out for, and why it could be the smart choice for your driveway.
Is Resurfacing a Viable Option?
Resurfacing refers to applying a new layer of tarmac (or asphalt) over the existing surface. This can extend the life of your driveway, improve appearance, and restore function. But it’s not just a cosmetic fix—it requires a solid base and stable substructure.
Resurfacing is generally possible if:
- The existing tarmac is structurally sound
- There are no major cracks or deep potholes
- Drainage is functioning correctly
- The surface is not loose, crumbling, or breaking up in large areas
In other words, resurfacing is ideal when your driveway is showing surface-level wear but the underlying construction is still intact.
When You Shouldn’t Resurface
It’s important to know when resurfacing is not advisable, as it can actually lead to further problems down the line. You should avoid overlaying tarmac if:
- The existing surface has significant structural cracks
- There is substantial movement, subsidence, or poor drainage
- The base layer has failed and is no longer level or compact
- Roots, frost damage, or oil contamination have compromised the integrity of the surface
In such cases, full removal and replacement is often the safer and more long-lasting solution.
Benefits of Tarmac Resurfacing
When appropriate, resurfacing offers several advantages over complete replacement:
- Faster turnaround – Less groundwork means quicker results
- Lower cost – You avoid full excavation and disposal fees
- Improved appearance – A fresh, black surface instantly revitalises your property
- Eco-friendliness – Reusing the base reduces material waste
- Extended surface life – A new layer of tarmac adds several years of performance
It’s a highly practical option for residential driveways, private roads, school grounds, and business forecourts alike.
What’s Involved in the Resurfacing Process?
Resurfacing is more than just pouring new tarmac on top. A professional resurfacing job typically involves:
- Cleaning and clearing the old surface of debris, oil, and moss
- Cutting out or repairing damaged areas to ensure a stable base
- Applying a bonding layer (such as tack coat) to ensure adhesion
- Laying the new tarmac evenly and at the correct depth
- Rolling and compacting to create a smooth, durable finish
The key is careful preparation—something we prioritise on every job at Stowmarket Driveway Services.
A Note on Height and Edging
One important consideration is the added height from the new tarmac layer. In some cases, this can affect:
- Thresholds to garages or doors
- Drainage gradients
- Existing edging or kerbs
Our team carefully evaluates and adjusts for these factors to ensure the resurfaced driveway blends seamlessly with your surroundings and performs as expected.
