Primary Aggregates in Landscaping: Durable and Sustainable Solutions

Aggregates are the backbone of any hard landscaping project. Functional yet stunning, primary aggregates like limestone, gravel, and sand have multiple uses for landscaping and deliver strength, durability, and aesthetics.

We’ve taken a closer look at primary aggregates and why you should use them in your next project.

What are primary aggregates? And what are they used for?

Put simply, primary aggregates naturally occur in environments like rivers, lakes, and quarries. Secondary aggregates, on the other hand, are byproducts of industrial or extractive processes and include metallurgical slag and incinerator ash.

Gravel, crushed stone, and sand are all examples of primary aggregates that combine aesthetics, quality, and performance, making them excellent materials for landscaping.

Thanks to their natural attributes, these naturally occurring stones and minerals are generally used for decorative purposes, including landscaping and other decorative projects.

What is the main purpose of aggregate?

Aggregates provide strength and stability for the construction of buildings, roads, and bridges. Primary, secondary, and recycled aggregates are used to pour foundations, create asphalt for roads, and provide drainage. They’re also a primary component of concrete.

Cost-effective and sustainable, these attributes make aggregates a perfect choice for landscaping projects.

What are the most common aggregates?

Gravel, crushed stone, sand, and recycled concrete are among the most common types of aggregates. Each has its own unique uses and properties, making them suitable for anything from driveways and drainage to borders and walkways.

What is the difference between sharp sand and normal sand?

As the name suggests, sharp sand has large, angular particles that create stronger and more durable bonds when dried.

It’s also a great choice for landscaping, adding bulk, drainage, and water retention to heavy clay soils. Sharp sand is the best choice for laying paving slabs or concreting posts that require stable and durable foundations.

What are the benefits of primary aggregates in landscaping?

We’ve already touched on some of the numerous benefits of primary aggregates for your landscaping projects. Here are some you may not have considered:

●        Aesthetics: Primary aggregates have a natural beauty that lends itself to being left exposed in paths and walkways. You can design with colour, size, and texture for landscaping projects that suit any style of property or the diverse needs of public spaces.

●        Low maintenance requirements: Once installed, primary aggregates need virtually no maintenance. Gravel aggregates are useful weed inhibitors, providing a sparse growing environment. Any weeds that do poke through are easy to spot and remove.

Aggregates may need to be refilled occasionally, but they deplete slowly, owing to their natural strength and durability.

●        Strength and stability: Using aggregates provides strength and stability, and they stay put once in place. Aggregates help prevent soil erosion and make a good alternative to mulch that can blow away.

As a bonus, aggregates lend a contemporary, streamlined look to any landscaping scheme.

●        Improved drainage: Effective drainage is often an issue. The use of aggregates allows surface water to drain, eliminating surface puddles and retaining water where needed. Good drainage also prevents your landscape design from becoming a muddy morass, giving it long-lasting appeal.

●        Environmentally friendly and sustainable: Primary aggregates are a natural and eco-aware choice for any public or private landscaping project that requires sustainability.

Crushed rock or gravel doesn’t require replacing year after year or treating with toxic chemicals. Primary aggregates won’t degrade quickly and are sourced directly from the natural environment, where they’re abundant. There’s a reduced contamination risk, meaning our primary aggregates meet the required standards and specifications.

●        Design versatility: When quality and consistency are key, primary aggregates deliver. Often preferred for their durability and consistency, primary aggregates are a fantastic choice for design versatility.

There are options to suit any project, and you can mix and match to get the effect you want. Aggregates can also be a decorative, low-maintenance alternative to grass as a cost-effective solution.

●        An affordable option: Aggregate stone is one of the most affordable landscaping options. Our competitive prices per tonne are lower than alternatives in the short term. Moreover, low maintenance and replacement costs make primary aggregates a fantastic investment in the long run.

Why is it important to ensure aggregate supplies are sourced responsibly?

Using locally sourced primary aggregates can reduce your project’s carbon footprint. However, there are other notable reasons for using sustainably sourced aggregate materials:

●      Cost-effective: Sourcing your primary aggregates locally reduces your transportation and processing costs. You’ll also contribute to reducing greenhouse gases, making sustainable sourcing environmentally beneficial.

●      Quality and compliance: Sustainably sourced aggregates help your project meet environmental and quality control standards, such as LEED and BREEAM. As a bonus, you’ll boost your credentials as a sustainable business.

●      Environmentally sustainable: Primary aggregates are incredibly hardwearing and won’t need replacing due to wear and tear. Natural stone and minerals degrade more slowly than secondary and recycled aggregates, giving them a lower environmental impact in the long term.

What is the difference between primary and recycled aggregates?

The clue is in the name. Recycled aggregates, including crushed concrete waste, are reclaimed from construction and demolition. That means they’re often cheaper than primary aggregates, making them an attractive alternative for landscaping.

While diverting waste from landfills is an environmental positive, there are drawbacks to using recycled aggregates for landscaping projects. If aesthetics are your priority, recycled aggregates may not be the best choice, though they can add a rustic charm to pathways and terraces.

The quality of recycled aggregates varies significantly, and contamination issues can occur. Recycled aggregates also tend to degrade more quickly and are susceptible to water damage. However, they can be affordable for your project when you choose quality products from reputable suppliers.

How to find the right primary aggregates for your project

Choosing the most suitable aggregates for your project can seem challenging. Primary aggregates like sharp sand and gravel are ideally suited to landscaping and decorative projects like parks and gardens.

Fine aggregates like crushed stone and gravel are ideal for garden beds when held back by a small retaining border. In addition to their decorative properties, gravel and crushed stone have excellent drainage properties and can be used to control water flow in drainage systems. They’re also an ideal mulch around trees and shrubs, letting plants establish while getting the water they need.

Sharp sand is the perfect choice for supporting benches and other landscaping elements where you need strength and the ability to stand up to wear and tear. Crushed stone is a tough and aesthetic choice for pathways and drives. Consider matching the colour and texture to the landscaping feature — for instance, limestone and crushed marble give a bright, sharp aesthetic to a water feature.

Primary aggregates like sharp sand and gravel create a robust mixture with superior load-bearing capabilities for concrete mixes and foundations. They also provide a strong, stable, durable base for access roads and tarmaced pathways.
