On-Grade Patio Systems

Creating your own functional patio space at ground level doesn’t have to be a complicated process. The reality, though, is that traditional on-grade patios often require heavy excavation to achieve a level base and poured concrete for stability. For many, this makes the process too time-consuming and messy to be appealing. The Outdoor Floor System provides a modern alternative that allows you to build a level, durable patio over grass, soil, or existing surfaces without the need for heavy foundations or invasive construction. This system supports a wide range of finishes, including stone and porcelain, while keeping the installation process quick and clean.

What Is an On-Grade Patio System?

An on-grade patio system is a ground-level outdoor deck or floor that sits directly on the earth or a prepared base. Unlike elevated decks, it does not rely on joists that are fixed above a structural substrate. Instead, it uses modular supports or pedestals to create a level platform, providing stability and proper drainage without heavy excavation or concrete work. Traditional patio construction often involves multiple layers such as crushed stone, sand, mortar, and pavers. All of these require precise installation and can be prone to shifting and cracking over time. The Outdoor Floor System replaces this with a modular platform that has been designed to provide even support and full drainage, as well as easy access for adjustments and maintenance.

How the Outdoor Floor System Works for On-Grade Patios

The system consists of adjustable pedestals or risers that are paired with interlocking composite panels or joists that form a stable grid for your patio surface. Pavers or tiles are then placed directly onto this grid, which creates a “floating” surface that distributes weight evenly and remains perfectly level, even over uneven ground. Because the system raises the patio slightly above the base, water is able to flow freely underneath. This greatly reduces the risk of pooling and keeps your pavers both dry and protected against the elements. The modular design also makes realignment and removal easy, and you can change individual panels without having to disturb the surrounding area. These qualities make the Outdoor Floor System ideal for patios that need to sit on top of grass, dirt, or existing slabs while remaining functional and visually appealing.

Benefits of Using the Outdoor Floor System for On-Grade Patios

1. Easy Installation

For the Outdoor Floor System, no heavy excavation or concrete pouring is required. It is easy and quick to assemble the modular system, meaning that you can minimize the disruption to your backyard.

2. Fully Drainable

Water is allowed to pass freely beneath the surface of the patio, which prevents it from pooling in unwanted areas. This protects your patio from water damage and also keeps the ground below nice and stable.

3. Level Surface on Uneven Ground

The adjustable pedestals can compensate for slight slopes, bumps, or inconsistencies in the base. This means that it’s easier than ever to achieve a flat, walkable surface from edge to edge.

4. Durable and Low-Maintenance

The composite frame and pedestals are designed to last by resisting moisture, UV exposure, and weathering. Each of the individual pavers or tiles can also be lifted as necessary for cleaning, repairs, or access to utilities.

5. Design Flexibility

The Outdoor Floor System supports a variety of surfaces including stone, porcelain, and structural tiles in multiple sizes and finishes, giving you complete creative freedom.

6. Environmentally Friendly

Since the system sits above the ground without altering drainage patterns, it’s minimally invasive and helps preserve existing landscaping and soil structure.

Common Applications

The Outdoor Floor System is well-suited for a wide range of on-grade patio scenarios:

• Backyard patios and dining areas
• Outdoor lounge zones for residential or commercial properties
• Walkways and garden paths
• Poolside or spa surround areas
• Areas over grass, sand, or compacted soil
• Over existing slabs or older patios that need resurfacing Its modular and lightweight design allows for easy installation and relocation if needed, making it ideal for both temporary and permanent patios.

How Installation Works

Building an on-grade patio with the Outdoor Floor System is a straightforward process. Though each patio will be slightly different, the installation will be as follows:

1. Prepare the Ground: First, it’s important to remove any debris from the area and level the soil if needed. Compact the soil lightly to create a stable base and add a layer of gravel for extra stability if needed.
2. Lay Out the Pedestals or Supports: Once your ground is prepared, you can position the adjustable pedestals in a grid based on the size of your tiles or pavers.
3. Install the Frame: Next, simply lock the interlocking panels or joists onto the pedestal tops to create your stable structural grid.
4. Place the Pavers or Tiles: Lay your chosen surface material directly onto the grid, adjusting the spacing and alignment as needed.
5. Secure the Edges: Once everything is in place, finish your patio by using perimeter trim or containment methods. This makes your patio look neat and tidy, and also prevents shifting of the pavers or tiles. And that’s it! Once your deck has been completed, the patio is immediately usable. No adhesives or mortar are required, and you end up with a level and drainable surface that’s tailored for your space.
