ICPI Paver Base: Everything You Need to Know

Designed to withstand heavy loads, resist settling, and promote proper drainage, the ICPI Paver Base ensures a long-lasting and visually appealing surface.

What Happens if You Don’t Use Paver Base?

The purpose of a paver base is to provide a stable and solid foundation for the pavers. Without a proper base, the pavers won’t be able to withstand the weight and pressure applied to them. This can lead to sinking, shifting, or cracking of the pavers, making them unsafe to walk on.

Additionally, without a paver base, water may not be properly drained away from the pavers. This can lead to the growth of mold, mildew, and weeds between the pavers. It can also cause erosion and washout, further destabilizing the pavers.

Neglecting to use a paver base can have detrimental effects on the longevity and safety of your pavers.

Importance of Proper Paver Base Materials: Discuss the Different Types of Materials That Can Be Used for a Paver Base, Such as Crushed Stone, Gravel, or Sand, and Explain Their Benefits and Drawbacks.

Choosing the right materials for a paver base is crucial for the long-term stability and durability of your project. There are several options available, including crushed stone, gravel, and sand.

Crushed stone is a popular choice due to it’s strength and stability. It provides a solid base that can withstand heavy loads and helps prevent shifting or settling. However, it may be more expensive and harder to work with compared to other materials.

Gravel is another common option for a paver base. It offers good drainage and is relatively easy to install. However, it may not provide as sturdy of a base as crushed stone and can shift over time.

Sand is often used as a leveling agent and joint filler for pavers. While it’s easy to work with, it lacks the strength and stability of crushed stone or gravel. Sand can wash away or erode over time, leading to uneven pavers.

Ultimately, the best choice for your paver base will depend on factors such as the type of pavers, the expected load, and the local climate. Consulting a professional or landscaping expert can help you determine the most suitable material for your specific project.

Properly preparing a base is essential for any paving project, regardless of the material being used. Whether it’s asphalt, concrete, stones, or even wood, a sturdy base is crucial for the longevity and durability of the pavers. If you’re looking for reliable guidance on paver base preparation, Unilock, a trusted company in the industry, offers a technical guide that provides valuable advice. By considering their expertise and following their recommendations, you can ensure that your pavers are being installed on a strong and stable base.

Is Paver Base Needed?

A proper base is essential for any paving project, regardless of the material used. Paving materials can include asphalt, concrete, stones such as flagstone, cobblestone, and setts, artificial stone, bricks, tiles, and sometimes even wood. Pavements, whether on sidewalks, road surfaces, patios, or courtyards, are an integral part of landscape architectures hardscape.

To ensure success in your stone project, we recommend referring to the Unilock technical guide. Unilock has been a pioneer in the industry, introducing concrete pavers to North America in 197With over 10 billion stones installed to date, Unilock offers unparalleled expertise in manufacturing premium paving products.

When it comes to placing the pavers, it’s crucial to have a substantial base. A paver base serves as a solid foundation, providing stability and preventing shifting and sinking of the pavers over time.

To ensure a durable base, it’s recommended to excavate the area to the appropriate depth, typically around 8-12 inches. Once excavated, the base should be filled with a compacted layer of crushed stone or gravel. This will create a stable foundation that can withstand the weight and pressure exerted on the pavers.

Additionally, it’s important to consider the climate and drainage when preparing the base. In regions with freeze-thaw cycles, it’s crucial to include proper drainage measures to prevent water from accumulating and causing damage to the base and the pavers. This can be achieved by incorporating a layer of geotextile fabric and perforated pipes to allow for proper water drainage.

Investing time and effort in preparing a proper base for your paver project is crucial for it’s long-term success.

The Impact of a Proper Paver Base on the Overall Durability and Longevity of a Paved Surface.

  • Increased stability
  • Reduced cracking
  • Improved drainage
  • Prevention of settlement
  • Enhanced load-bearing capacity
  • Resistance to shifting and movement
  • Longer lifespan
  • Minimized maintenance
  • Prevention of uneven surfaces
  • Protection against frost damage

This mixture provides a solid base for pavers, allowing for water drainage and easy installation. In addition, the use of quarry processed dense grade aggregate ensures stability and durability for the paver project.

What Is the Best Base for Pavers?

ICPI paver base is an essential component for any successful paver installation. When it comes to choosing the best base for your pavers, crushed stone is a top contender. Why? Well, it offers several advantages that make it an ideal choice for creating a solid and long-lasting base.

Firstly, crushed stone allows for effective water drainage. This is crucial because proper drainage prevents water from pooling underneath the pavers, which can lead to shifting and settling over time. The porous nature of crushed stone allows water to penetrate and flow away, ensuring that your pavers stay in place and maintain their stability.

Additionally, crushed stone is easy to work with. It’s small size and uniform shape make it incredibly compactable, allowing for easy levelling and a smooth surface.

When it comes to choosing the right type of crushed stone for your paver base, opt for a quarry-processed dense grade aggregate. The stone dust helps to fill in any voids and ensures a tight interlock between the pavers, enhancing their overall strength and durability.

It’s important to note that not all crushed stone is created equal. Be sure to source your aggregate from a reputable quarry that adheres to industry standards. This will ensure that you receive high-quality crushed stone that’s free of impurities and has consistent grading.

It’s excellent drainage properties, ease of use, and durability make it the go-to option for creating a solid and stable foundation.

The Difference Between a Paver Base and a Paver Sand Layer

  • A paver base provides structural support and stability for the pavers.
  • It’s usually made up of crushed stone or gravel and compacted to create a solid and level foundation.
  • The paver sand layer is used to fill the gaps and provide a smooth surface for laying the pavers.
  • It’s finer in texture compared to the paver base and allows for proper drainage.
  • The paver sand layer helps to lock the pavers in place and prevent shifting.
  • While the paver base is responsible for load-bearing and stability, the paver sand layer is more about aesthetics and joint stability.
  • It’s important to properly prepare both the paver base and paver sand layer before laying the pavers to ensure a long-lasting and durable installation.


From providing proper drainage to preventing settling and shifting, the selection and installation of the right paver base material can greatly impact the overall performance and durability of the paved surface. By adhering to the guidelines set by the Interlocking Concrete Pavement Institute and using high-quality base materials, homeowners and contractors can create a solid foundation that will withstand the test of time.
