In this article, we will explore this topic in detail, discussing the pros and cons, as well as the best practices of installing composite decking on the ground.
Understanding Composite Decking:
Before we dive into the discussion around ground installation, let’s briefly understand composite decking. Composite decking is a combination of wood fibers and recycled plastic. This composition gives it exceptional strength and resistance to rot, insects, and decay. Its low-maintenance nature eliminates the need for staining, sealing, or sanding, making it an attractive option for homeowners seeking a durable and hassle-free deck surface.
Pros and Cons of Ground Installation:
Pros:
- Cost-saving: Installing composite decking directly on the ground eliminates the need for expensive substructures like joists or concrete footings, reducing installation costs.
- Accessibility: Ground-level decking provides easier access for individuals with mobility issues and eliminates the need for stairs or ramps.
- Versatility: Installing on the ground offers more flexibility in terms of design and allows for seamless integration with surrounding landscapes.
Cons:
- Moisture Retention: Installing composite decking directly on the ground may lead to increased moisture retention, potentially resulting in mold, mildew, or decay over time.
- Uneven Surface: The ground may not provide a perfectly level surface, requiring additional leveling or grading efforts before installation.
- Limited Air Circulation: The lack of airflow beneath the decking may increase the chance of moisture buildup, leading to potential issues.
Best Practices for Ground Installation:
1. Preparation:
- Clear the area of any vegetation, debris or rocks that may affect the installation process.
- Determine the desired size and layout of the composite deck, considering any existing structures or trees.
2. Foundation:
- Level the ground: Ensure the ground is properly leveled by removing high spots and filling in any low areas.
- Create a weed barrier: Lay a layer of landscaping fabric or a weed barrier to prevent weed growth beneath the deck.
3. Installation:
- Position the boards: Start by laying the first row of composite boards along the perimeter, ensuring adequate spacing between boards as per the manufacturer’s recommendations.
- Secure the boards: Attach the composite decking boards to each other using recommended clips or screws, ensuring a secure and uniform installation.
- Incorporate a slight slope: To facilitate drainage and minimize water accumulation, incorporate a slight downward slope away from the house.
4. Maintenance:
- Regular cleaning: To prevent the buildup of dirt, debris, or organic matter, regularly sweep or hose down the composite deck surface.
- Address moisture concerns: If moisture retention becomes an issue, use a deck drainage system or consider incorporating a gravel base beneath the deck to improve drainage.
Installing composite decking directly on the ground is indeed possible, but it comes with both advantages and disadvantages. While it offers cost-saving benefits and accessibility advantages, there are concerns around moisture retention and uneven surfaces. By following the best practices for ground installation, ensuring proper preparation, foundation, and maintenance, you can enjoy a beautiful and long-lasting composite deck that meets your needs and enhances your outdoor living space.
