When deciding on a surface material for driveways, pathways, or parking areas, the choice often boils down to tarmac or gravel. Each material offers distinct advantages and disadvantages, making it important to weigh factors like cost, durability, maintenance, and aesthetics before deciding.
In this blog, we’ll delve into the differences between tarmac and gravel, exploring their benefits and drawbacks to help you determine the best option for your specific needs. Whether you prioritise functionality, appearance, or sustainability, this guide will steer you in the right direction.
Expert Installation for Optimal Results
Whether you choose tarmac or gravel, professional installation is crucial for a high-quality, long-lasting surface. Experts like Kane Construction ensure proper preparation, material application, and finishing for a flawless result.
What is Tarmac?
Tarmac, short for tarmacadam, is a durable material made by mixing crushed stone or aggregate with bitumen. Commonly used in roads, driveways, and car parks, tarmac is known for its smooth and resilient surface.
What is Gravel?
Gravel is a loose collection of small stones and rocks, available in various sizes and colours. Its versatility and natural appearance make it a popular choice for landscaping and driveways.
Key Factors to Consider When Choosing a Surface
1. Durability
● Tarmac:
Tarmac is highly durable and can withstand heavy loads, making it an excellent option for high-traffic areas. It resists wear and tear from vehicles and weather, offering a lifespan of 10–20 years with proper maintenance.
● Gravel:
Gravel is less durable, especially under heavy traffic, as it tends to shift and scatter over time. However, it is resilient against water damage and frost, making it a good choice in areas with variable weather.
2. Aesthetics
● Tarmac:
Tarmac provides a clean, uniform appearance suitable for modern properties and professional environments. While its aesthetic appeal is limited to a classic black finish, its sleek look complements various architectural styles.
● Gravel:
Gravel offers a more rustic and natural look. Available in a wide range of colours and textures, it can be tailored to match any design scheme, making it ideal for countryside homes or garden pathways.
3. Cost
● Tarmac:
The initial cost of installing tarmac is higher due to the materials and labour involved. However, its long lifespan can make it cost-effective in the long run.
● Gravel:
Gravel is one of the most affordable surface materials, both in terms of material cost and installation. Maintenance expenses, such as replenishing displaced gravel, can add up over time.
4. Maintenance
● Tarmac:
Maintenance for the tarmac is minimal, requiring occasional sealing to maintain its smooth finish and prevent cracks. Repairs are straightforward and can prolong its life significantly.
● Gravel:
Gravel requires more frequent upkeep, including raking to redistribute stones and replenishing areas where gravel has been displaced. Weed control can also be a concern, necessitating regular attention.
5. Drainage
● Tarmac:
Tarmac is non-porous, so proper drainage systems are necessary to prevent water pooling and surface damage.
● Gravel:
Gravel excels in drainage due to its porous nature, allowing water to flow through easily and reducing the risk of flooding or surface erosion.
6. Noise and Comfort
● Tarmac:
Tarmac provides a smooth and quiet surface for vehicles and pedestrians, reducing noise levels compared to other materials.
● Gravel:
Gravel produces crunching sounds when walked or driven on, which some find charming while others may find intrusive. Loose stones can also be uncomfortable to walk on, especially without proper footwear.
Environmental Considerations
Tarmac:
While durable, tarmac is less eco-friendly due to the petroleum-based bitumen used in its production. Recycling old tarmac can help offset its environmental impact.
Gravel:
Gravel is a natural material with a smaller carbon footprint. Its ability to allow water infiltration makes it an environmentally friendly choice for areas prone to runoff or flooding.
Common Applications for Tarmac and Gravel
Tarmac:
● Driveways for urban and suburban homes.
● Parking lots and commercial spaces.
● High-traffic pathways and roads.
Gravel:
● Garden pathways and decorative landscaping.
● Countryside or rural driveways.
● Parking areas with lighter traffic.
Installation Process
Tarmac Installation:
- Preparation: Clear the area and level the ground.
- Base Layer: Lay a crushed stone base to provide stability.
- Tarmac Application: Apply the tarmac in layers, compacting each one for a smooth finish.
- Curing: Allow the surface to cure before use, typically within 24–48 hours.
Gravel Installation:
- Ground Preparation: Remove vegetation and level the area.
- Weed Barrier: Lay a geotextile fabric to prevent weed growth.
- Base Layer: Add a compacted base of crushed stone for stability.
- Top Layer: Spread gravel evenly across the surface and rake into place.
