When it comes to installing landscape pavers, one of the key elements that play a crucial role in the durability and longevity of your project is the material you put underneath them. Proper preparation of the base is essential to ensure that your pavers stay in place and don’t shift over time. In this article, we will explore the different options available for what to put under landscape pavers.
Dense Graded Base (Sand-set)
A sand-set paver base is a classic and widely used method for installing landscape pavers. This approach involves creating a layer of sand as a cushion between the base material and the pavers themselves. Once the sand is laid down, the pavers are positioned on top of it and then firmly pressed into place. This method provides a level surface for the pavers to sit on and helps with proper drainage.
Aggregate Base
Another popular option for what to put under landscape pavers is an aggregate base. This typically involves using a combination of crushed stone, gravel, and sand to create a sturdy foundation for the pavers. The aggregate base helps to distribute weight evenly across the surface, reducing the risk of individual pavers sinking or shifting over time. It also aids in promoting proper drainage, preventing the buildup of water beneath the pavers.
Concrete Base
For projects that require maximum stability and strength, a concrete base can be used underneath landscape pavers. This method involves pouring a layer of concrete onto the prepared ground and then laying the pavers directly on top of it. A concrete base provides exceptional durability and longevity, ideal for high-traffic areas or heavy-duty applications where pavers are subjected to significant weight or pressure.
Interlocking Grid System
An innovative solution for what to put under landscape pavers is an interlocking grid system. These grids are made from durable materials such as plastic or recycled rubber and feature a web-like structure that helps to evenly distribute weight and reduce the risk of paver movement. The grids can be filled with gravel or soil to create a stable base for the pavers to rest on, offering excellent support while allowing for water drainage.
Permeable Paver Base
For eco-conscious homeowners looking to minimize water runoff and promote sustainable landscaping, a permeable paver base can be an excellent choice. This type of base consists of porous materials that allow water to infiltrate the ground below, reducing the risk of erosion and surface flooding. Permeable bases are typically made from materials like crushed stone or permeable concrete, providing a stable foundation for pavers while still allowing for natural drainage.
Asphalt Base
In some cases, an asphalt base may be used underneath landscape pavers, especially in areas where a strong and flexible foundation is required. Asphalt provides excellent load-bearing capacity and resistance to changes in temperature and humidity, making it a suitable choice for driveways or other high-traffic areas. However, it’s essential to ensure proper compaction and thickness when using an asphalt base to prevent sinking or shifting of the pavers.
Choosing the Right Base Material
When deciding what to put under landscape pavers, it’s essential to consider the specific requirements of your project, such as the intended use of the area, the level of foot traffic, and the local climate conditions. Each type of base material comes with its advantages and limitations, so weighing these factors against your goals and budget will help you make an informed decision. Consult with a paver installation professional to determine the best base material for your project and ensure a successful outcome.
