Block Paving vs Tarmac in Winter: Which Surface Performs Better?

Choosing the right driveway surface is an important decision for homeowners in South East England—and the winter months are often when the true performance of your driveway is put to the test. Cold temperatures, heavy rainfall, early frosts and limited daylight all highlight the strengths (and weaknesses) of the surface material you choose.

At Crown Paving, two of the most popular options we install are block paving and tarmac. Each has its own advantages, but how do they stack up when faced with winter weather?

In this blog, we compare block paving and tarmac across several key categories to help you make an informed decision—especially if you’re considering a new driveway in the coming months.

1. Cold Weather Resilience

Tarmac is known for its flexibility and ability to withstand cold weather without cracking. The smooth surface copes well with expansion and contraction caused by temperature fluctuations. However, older or poorly laid tarmac can become brittle over time and may show signs of cracking after prolonged exposure to frost.

Block paving, on the other hand, is made up of individual units laid over a stable sub-base. These blocks can shift slightly in response to ground movement, which helps prevent cracks and long-term damage. If an individual block becomes damaged, it can be easily replaced—making block paving highly practical during and after winter.

Verdict: Both surfaces perform well, but block paving offers more flexibility in terms of repairs.

2. Surface Water and Drainage

Winter in South East England often brings periods of heavy rainfall, and good drainage is essential to prevent puddling, surface damage and icy patches.

Block paving is typically laid with slight gaps filled with kiln-dried sand, allowing surface water to drain naturally. Permeable block systems are also available, which are designed to let water pass through to the sub-base—helping reduce run-off and prevent water from freezing on the surface.

Tarmac is non-permeable, meaning water will need to run off into nearby drains or onto adjacent surfaces. If installed with the correct slope and drainage channels, this won’t be a problem—but poorly graded tarmac surfaces can suffer from standing water.

Verdict: Block paving has better built-in drainage potential, especially with permeable options.

3. Grip and Safety in Frosty Conditions

When temperatures drop and frost appears, driveways can become slippery—particularly when combined with fallen leaves or standing water.

Tarmac provides good grip for both vehicles and foot traffic, but as the surface wears down over time, it may become smoother and more slippery in icy weather.

Block paving, especially textured or rumbled blocks, tends to offer superior traction. The jointing sand between the blocks can also help reduce slippage, making it a safe option for those concerned about icy mornings.

Verdict: Block paving generally offers better grip and is safer in frosty conditions.

4. Maintenance During Winter

When it comes to ease of maintenance, tarmac is the more straightforward option. It requires very little attention beyond the occasional sweep, and its smooth surface makes it easy to clear snow or remove debris.

Block paving may need slightly more attention in winter. The sand between the joints can erode over time due to rain and frost, and weeds or moss may develop if not regularly swept or treated. However, if properly maintained, block paving remains attractive and functional for years.

Verdict: Tarmac is lower maintenance, but block paving offers more aesthetic value with a little upkeep.

5. Appearance and Kerb Appeal

While not a performance issue as such, winter can make outdoor areas look dull or uninviting. The clean, uniform appearance of tarmac is practical, but it can appear quite stark during the winter months.

Block paving, with its wide range of colours, patterns and finishes, adds visual interest to your property all year round. Even in gloomy weather, a well-laid block paved drive enhances kerb appeal and blends better with traditional and modern homes alike.

Verdict: Block paving wins for aesthetics, especially during the grey months of winter.

Conclusion: Which Should You Choose?

There’s no one-size-fits-all answer—it depends on your priorities, property type and budget. However, here’s a quick winter-focused comparison:

If you’re looking for visual appeal, flexibility and excellent drainage, block paving is a fantastic choice. If you prefer a cost-effective, low-maintenance surface that holds up well to winter wear, tarmac may suit you better.
