Can You Resurface a Tarmac Driveway That Has Started to Crack?

Cracks in a tarmac driveway do not necessarily mean that the entire surface needs to be removed and replaced. In many cases, resurfacing can restore a worn driveway and provide a fresh, durable finish. However, whether resurfacing is suitable depends on something far more important than the appearance of the cracks: the condition of the structure beneath the existing tarmac.

For homeowners in Aldershot, Hampshire, understanding why cracks have developed is the first step towards choosing the correct solution. At NS Driveways Aldershot, we assess the existing surface, underlying base, drainage and extent of deterioration before recommending whether resurfacing or more extensive reconstruction is appropriate.

What Does Tarmac Resurfacing Involve?

Tarmac resurfacing involves preparing an existing driveway and installing a new surface course over a suitable, stable base.

Rather than automatically excavating the entire driveway, the existing construction may be retained where it remains structurally sound.

A professional resurfacing project typically involves:

• Assessing the existing driveway
• Identifying damaged or unstable areas
• Carrying out necessary preparation
• Correcting local defects where appropriate
• Preparing edges and levels
• Applying and compacting the new tarmac surface

The key point is that the existing driveway must provide suitable support for the new surface.

Why Do Tarmac Driveways Start Cracking?

Cracks are symptoms rather than the complete problem

Before resurfacing, it is important to determine why cracking has occurred.

Possible causes include:

• Natural ageing and weathering
• Movement within the underlying base
• Poor initial ground preparation
• Repeated heavy vehicle loading
• Water entering weakened areas
• Inadequate drainage
• Deterioration around driveway edges

The cause matters because simply covering structural cracks with new tarmac may allow the same problem to eventually affect the resurfaced layer.

When Can a Cracked Tarmac Driveway Be Resurfaced?

Surface deterioration does not always mean structural failure

Resurfacing can be an effective option when cracking is relatively limited and the underlying driveway remains stable.

A driveway may be suitable for resurfacing when:

• The base remains firm
• There is no widespread movement
• Cracking is primarily within the surface layer
• Levels remain generally consistent
• Drainage continues to function effectively
• Localised defects can be repaired during preparation

In these circumstances, resurfacing can renew the appearance and performance of the driveway without unnecessarily rebuilding sound underlying construction.

When Are Cracks Too Serious for Resurfacing Alone?

Not every cracked driveway should simply receive another layer of tarmac.

Extensive cracking can sometimes indicate that the problem originates deeper within the driveway construction.

Warning signs can include:

• Large interconnected cracks
• Noticeable depressions
• Areas that move under vehicle loads
• Significant sinking
• Repeated cracking after previous repairs
• Widespread surface deformation

If the underlying base is unstable, placing new tarmac directly over it will not correct the source of the movement.

Why the Sub-Base Is So Important

A tarmac driveway is only as reliable as its foundation

The visible tarmac surface is only the upper part of the driveway.

Below it sits the supporting construction that distributes vehicle loads and helps maintain a stable surface. If this foundation has been properly prepared and remains in good condition, resurfacing may be entirely practical.

If the base has weakened or moved, however, the new surface may eventually follow that movement.

This is why professional assessment should consider what is happening beneath the cracks rather than focusing solely on covering them.

Can Individual Cracks Be Repaired Before Resurfacing?

Where cracking is localised, suitable preparation can often be carried out before the new surface is installed.

Depending on the condition of the driveway, this may involve:

• Removing loose material
• Repairing isolated damaged sections
• Correcting unstable areas
• Preparing existing cracks
• Improving transitions between old and repaired surfaces

The objective is to create a sound and properly prepared foundation for the new tarmac.

Why Simply Laying Tarmac Over Cracks Can Be a Mistake

Existing defects can transfer through the new surface

A new layer of tarmac can improve appearance immediately, but resurfacing should never be treated as a way of hiding unresolved structural problems.

If substantial cracks remain active underneath, movement can eventually transfer into the new surface. This can lead to cracking becoming visible again.

Professional preparation therefore makes a considerable difference to the longevity of resurfacing.

The driveway should be repaired and prepared according to its actual condition before the final surface is installed.

Drainage Should Be Checked Before Resurfacing

Water is an important consideration when assessing any deteriorating driveway.

Poor drainage can allow water to collect around weakened areas or penetrate defects. Over time, this can contribute to deterioration beneath the surface.

Before resurfacing, attention should be given to:

• Existing driveway falls
• Areas where water collects
• Drainage channels
• Surface levels
• How water leaves the driveway

Installing a new surface without considering an existing drainage problem may leave one of the causes of deterioration unresolved.

Driveway Edges Also Need Attention

Strong edges help support the surface

Cracking sometimes develops near the sides of a driveway where the tarmac lacks adequate support.

Vehicles repeatedly travelling close to unsupported edges can place additional stress on these areas.

Appropriate edging can help:

• Retain the driveway structure
• Reduce lateral movement
• Create a defined boundary
• Support vulnerable perimeter areas
• Produce a neater finished appearance

Edge condition should therefore form part of the assessment before resurfacing begins.

Resurfacing Can Transform a Tired Driveway

When the underlying construction remains suitable, resurfacing can make a substantial difference to an ageing driveway.

A professionally resurfaced tarmac driveway can provide:

• A smooth, consistent finish
• Improved appearance
• Renewed surface performance
• Clearer, neater edges
• A practical surface for everyday vehicle use

It can be particularly effective when the driveway has become visually worn but has not suffered major structural deterioration.

Resurfacing Versus Complete Reconstruction

The correct option depends on the condition beneath the surface

There is an important distinction between a driveway that looks worn and one that has structurally failed.

Resurfacing is generally suited to driveways where the existing foundation remains dependable.

More extensive reconstruction may be required when there is:

• Significant base movement
• Widespread sinking
• Severe deformation
• Extensive structural cracking
• Large unstable areas

A professional driveway contractor should determine which situation applies before recommending the work.

Why Professional Assessment Matters

Cracks can provide useful clues about what is happening beneath a tarmac driveway.

Their position, pattern and severity can help indicate whether deterioration is confined to the surface or associated with deeper movement.

At NS Driveways Aldershot, we assess the complete driveway rather than automatically recommending resurfacing. This allows preparation and installation to be matched to the actual condition of the existing construction, providing a more dependable result.

Professional Tarmac Driveways in Aldershot

For homeowners in Aldershot, Hampshire, a cracked tarmac driveway does not automatically mean complete reconstruction is necessary.

Where the underlying base remains stable, careful repairs and professional resurfacing can restore a smooth and attractive surface. Where deeper problems are identified, addressing them properly before installing new tarmac helps prevent the same defects from quickly returning.

NS Driveways Aldershot provides professional tarmac driveway installation and resurfacing with careful attention to preparation, drainage, edging and surface finishing.

Conclusion

Yes, a tarmac driveway that has started to crack can often be resurfaced, but only when the existing construction is suitable. Minor surface cracking and general wear may be corrected through careful preparation followed by a new tarmac surface. Widespread cracking, sinking or movement, however, can indicate problems within the underlying base that resurfacing alone cannot solve.

The most important step is therefore identifying why the driveway has cracked before deciding how it should be restored.

If your tarmac driveway in Aldershot, Hampshire is cracked or showing signs of deterioration, contact NS Driveways Aldershot. We can assess its condition and recommend whether professional resurfacing or more extensive preparation is the most appropriate way to achieve a durable, well-finished driveway.
