Stamped Concrete vs. Exposed Aggregate: Which is Right for You?

What is Stamped Concrete?

Stamped concrete, a favorite among many homeowners and businesses in Fredericton, is a type of decorative concrete that is patterned or textured to mimic the look of other materials such as brick, stone, wood, and even seashells. The versatility of stamped concrete in terms of design and color options makes it a cost-effective alternative to these materials.

Installation Process

Installing stamped concrete involves a series of steps. First, the concrete is poured and leveled. Then, color is added either in the mixer (integral coloring) or after the concrete is placed (surface or broadcast coloring). A release agent is then applied to prevent the texturizing mats from sticking to the concrete. The mats are laid out in succession to imprint the desired pattern onto the concrete. After a day of drying, the release agent is removed by pressure washing, and the surface is sealed.

Pros of Using Stamped Concrete

1. Aesthetics

Stamped concrete is highly valued for its aesthetic appeal. It can replicate a wide range of patterns and textures, making it a popular choice for homeowners looking to add a touch of elegance to their outdoor spaces.

2. Versatility

Stamped concrete is versatile and can be used in a variety of applications, including patios, driveways, walkways, and even interior floors. It can be customized to match the existing décor or landscape, making it a flexible choice for different types of projects.

3. Durability

Stamped concrete forms a continuous, solid surface that doesn’t allow weeds to grow through the cracks, unlike pavers and cobbles. It can also be reinforced with rods for added strength, making it a durable choice for outdoor spaces.

Cons of Using Stamped Concrete

1. Maintenance

While stamped concrete is durable, it does require some maintenance. It needs to be resealed every few years to maintain its color and prevent it from becoming dull.

2. Cost

The cost of installing stamped concrete can be higher than other types of paving project due to the additional materials and labor involved in the stamping process.

3. Difficulty in the Installation Process

The process of installing stamped concrete is more complex than that of regular concrete. It requires special tools and skills and is not typically a do-it-yourself project.

What is Exposed Aggregate

Exposed aggregate concrete gives your driveway, walkway or patio an interesting textured look. They remove part of the top layer of concrete to reveal the small stones underneath. This exposes the aggregate, which are the stones mixed into the concrete.

The exposed aggregate finish provides a nice look and feel that withstands use well. It’s often used for places you walk a lot like driveways, sidewalks, patios and around pools.

Installation Process

Doing exposed aggregate concrete is a multi-step job.

First, they pour the concrete with rocks mixed in.

Once the concrete is poured flat, they spray on a retarder chemical to slow the hardening of just the top layer.

Then after the concrete sets a bit, they remove part of the top layer – usually by washing or sandblasting it off. This reveals the rocks mixed inside, called the aggregate.

After exposing the aggregate, they apply a sealer to protect it and make the colors pop.

That gives you the tough, textured look of exposed aggregate concrete that’s long-lasting for places like your driveway, walkway or patio.

Pros of Using Exposed Aggregate

1. Durability

Exposed aggregate is extremely durable and can withstand heavy traffic and harsh weather conditions. It is also resistant to skidding, making it a safe choice for driveways and pool decks.

2. Low Maintenance

Exposed aggregate is low maintenance. It does not need to be resealed as often as stamped concrete, and it is less likely to show stains and marks due to its textured surface.

Cons of Using Exposed Aggregate

1. Limited Color Options

While exposed aggregate offers a variety of textures, the color options are limited to the colors of the aggregate. This can limit the design options compared to stamped concrete, which can be colored to match any desired hue.

2. Difficulty in Achieving Uniformity

Due to the nature of the material, achieving a uniform look with exposed aggregate can be challenging. The size, shape, and distribution of the aggregate can vary, leading to an inconsistent appearance.

3. Surface Slipperiness

While exposed aggregate is skid-resistant, it can be slippery when wet, especially if the aggregate is polished. This can pose a safety risk, particularly in areas like pool decks.

Comparing Stamped Concrete Or Exposed Aggregate

Cost Comparison

Both stamped concrete and exposed aggregate are cost-effective options for outdoor spaces. However, exposed aggregate is generally more affordable than stamped concrete. The cost of installing stamped concrete can start at around $120 per square meter, while an exposed aggregate finish can start at around $100 per square meter. These costs can vary depending on the materials, contractor, size of the project, and location.

Looks and Styles

In terms of aesthetics, both stamped concrete and exposed aggregate offer unique looks. Stamped concrete can mimic a wide range of patterns and textures, making it a versatile choice for different design preferences. On the other hand, exposed aggregate provides a more natural and earthy look, which can complement a variety of landscapes.

Durability of Both Options

Both stamped concrete and exposed aggregate are durable options that can withstand heavy traffic and harsh weather conditions. However, exposed aggregate is generally considered more durable than stamped concrete. It can resist hot and cold temperatures and is more efficient for pathways and driveways because it can handle heavy traffic and vehicles.

Maintenance Requirements

Stamped concrete requires regular resealing to maintain its color and prevent it from becoming dull. On the other hand, exposed aggregate is low maintenance and does not need to be resealed as often. It is also less likely to show stains and marks due to its textured surface.

Ease of Installation

The process of installing stamped concrete is more complex and requires special tools and skills. On the other hand, while the process of installing exposed aggregate is also complex, it is generally considered easier than installing stamped concrete.
