Concrete Colours for Driveways

What is Coloured Concrete?

Coloured concrete is traditional concrete mixed with stains, dyes or pigments to achieve a wide range of shades and effects. This type of concrete is created when colour is added to the base concrete mixture. The two main methods of adding colour to concrete are integral and surface colouring.

Integral Colouring

This process is when the pigment is mixed into the concrete during batching which gives the entire slab of concrete a uniform colour. Once the colour is chosen, it will be in a powder liquid or granular form. The pigments are then added to the cement, aggregates and water as the wet mix is prepared. The mixer runs for about 15 minutes to ensure all of the colour is evenly dispersed throughout the entire batch. The concrete that is coloured is then poured as usual, maintaining consistent slump and avoiding water which can lighten the colour. Integral colouring embeds colour throughout the entire material. It is highly durable and chips or surface wear reveal the same colour underneath so damage is less noticeable.

Surface colour

Surface colour is the process of applying colour just to the top layer of the concrete. The colour forms on the surface of the concrete and penetrates only the first layer. With paints and hardeners, it can also form a coating on the concrete surface. Methods for surface colouring concrete include techniques like applying stains, dyes or colour hardeners.

• Concrete stains: These can be acid based stains or water based and each are colourants that penetrate and transform the look of the concrete. Acid based stains chemically react with the concrete’s hydrated lime to create permanent surface colour. Water based stains have no chemical reaction but rather the colour penetrates the pores of the concrete and deposits pigments. The stain is typically applied using a brush, roller or plastic sprayer, working in small actions and avoiding overlapping marks. Both methods require drying time between layers to deepen the colour.
• Concrete dyes: Concrete dye uses tiny particles to deeply penetrate the concrete and create a layer of colour on the surface. The coloured particles soak into the porous concrete surface to permanently change the colour.
• Colour hardeners: These are cement based powders with pigments that are applied to fresh concrete to create a harder and more durable surface while adding long-lasting colour. This type of surface colour is often used for decorative finishes like stamped concrete. These hardeners are made from cement, sand and pigment and broadcast in multiple even coats over freshly poured concrete. It is then troweled into the surface and repeated for deeper, more even colour.

Benefits of Coloured Concrete for Driveway

Coloured concrete has so many benefits from decor and aesthetic appeal to increasing longevity. The main benefits of coloured concrete on the driveway are:

• Enhanced curb appeal: Coloured concrete instantly improves the appearance of the home and driveway. The wide range of colour options means homeowners can choose from a variety of colours and tones to suit their home facade and landscaping. The right colour driveway will match and complement these existing exterior elements like the roof, stone accents or trim. The driveway brings each element together to work in unison. Warm, earth tones of terracotta or sandstone on the driveway will pair beautifully with a rustic or traditional home with lush greenery. Cool charcoals and slate greys complement modern minimalist style architecture.
• Long lasting colour: Colour mixed into the concrete through the integral process ensures longevity as it runs through the slab rather than sitting on the surface. The colour on this type of coloured driveway will not fade, chip or peel even when exposed to the elements.
• Durability and strength: When concrete is coloured it offers the same strength and load bearing capacity as standard concrete. Coloured concrete can withstand heavy machinery, foot traffic and daily use without deteriorating. High-quality coloured concrete is made with the same base materials as standard concrete and is designed to meet or exceed the same structural requirements.
• Low maintenance: When driveway concrete is coloured, it requires minimal maintenance. The coloured materials offer durability and long-lasting colour with only minor upkeep. Occasional cleaning and resealing helps to maintain colour but they rarely need frequent repairs or repainting like other driveway materials.
• Versatile design options: When coloured concrete is combined with finishes like patterns, polished surfaces or stamped patterns, it provides versatile design options. This allows homeowners to achieve any look that appeals from sleek and modern to contemporary and traditional.
• Seamless finish: The colour consistency and the fact concrete is poured in one continuous surface creates a smooth and seamless finish. Unlike other driveway types like tiling or stone that have joints or gaps, concrete driveways have a cleaner look with no ongoing maintenance.
• Vast colour options: There is a wide range of colour choices for concrete driveways with everything from timeless neutrals like tan and grey to to warm earth tones and vibrant pops of colour.
• Slip resistance: Coloured concrete is slip resistant primarily due to the textured finishes applied during installation. These techniques create a rougher surface which helps with slip resistance.

• Stain concealment: Darker or textured concrete combined with finishes like exposed aggregate helps to hide driveway stains like oils from cars, tyre marks and dirt.
• Weather resistance: Coloured concrete is extremely weather resistant and is ideal for a variety of climates. Properly sealed coloured driveways resist moisture penetration or cracking from temperature extremes and sun exposure.
• Increase property value: A coloured concrete driveway boosts property value by creating a strong first impression for potential buyers. When the driveway complements the house and surrounding landscape, it has superior street appeal which is a positive factor in a competitive property market.

How to Choose Concrete Colour for a Driveway

When choosing the concrete colour for a driveway, there are a number of considerations to take into account. To choose the right colour palette, think about the style and aesthetics of the facade of the home, outdoor elements, and functionality. Considering these factors will help you make the right choice.

• Home style and exterior palette: The driveway should complement the exterior of the home and architecture. This includes factors like colour palette on the walls, the roof and fences. It is important to match the home’s style to blend seamlessly with the driveway colour to ensure street appeal. If the facade of the home is constructed of stone, choose an element of the stone and match with the driveway.
• Climate and heat absorption: Consider the climate and heat absorption when choosing the colour of the driveway. Darker colours will absorb more heat and will become very hot under direct sunlight. Warmer climates may be more suitable for lighter shades as they reflect heat more effectively.
• Stain resistance and maintenance: Take into account that light colour driveways will be more inclined to show stains like tyre or oil marks. Choose darker colours for concealing more stains and everyday wear.
• Neighbourhood aesthetics and regulations: When choosing the colour for the driveway, consider neighbourhood aesthetics and regulations. Some areas like new estates have specific design guidelines to mandate certain colours or material types on house facades. Make sure the driveway colour also ensures visual harmony within the neighbourhood.

Choosing the right concrete colour is an important decision that has an impact on appearance and functionality. The right colour will enhance the home and improve property value.
