What To Put Under A Low Deck

A low deck can enhance your outdoor living space, providing a cozy area for relaxation and entertainment. However, maintaining the area under a low deck can be challenging due to limited clearance and potential moisture buildup. Properly managing this space is essential to prevent issues like wood rot, mold, and pest infestations. Here’s a guide on what to put under a low deck to keep it dry, clean, and functional.

Understanding the Challenges of Low Decks

Limited Clearance

Low decks, often called ground-level decks, have minimal space between the deck boards and the ground. This makes it difficult to access the area for maintenance and increases the risk of moisture buildup.

Moisture Control

Without proper drainage and moisture control, the area under a low deck can become damp, leading to wood rot, mold growth, and attracting pests.

Weed and Pest Prevention

Low decks are closer to the ground, making them more susceptible to weed growth and pest infestations. Effective solutions are needed to keep these issues at bay. For tough terrains including low decks, building deck on slope can make a notable difference.

Best Materials to Use Under a Low Deck

1. Landscape Fabric

Benefits

Landscape fabric is an excellent choice for preventing weed growth and allowing water to drain. It’s easy to install and helps maintain a clean and dry environment under your deck.

Installation

  1. Prepare the Area: Clear any debris, rocks, and vegetation from under the deck.
  2. Lay the Fabric: Roll out the landscape fabric, ensuring it covers the entire area under the deck.
  3. Secure the Edges: Use landscape staples or rocks to hold the fabric in place and prevent it from shifting.

2. Gravel or Crushed Stone

Benefits

Gravel or crushed stone provides excellent drainage, preventing water from pooling under your deck. It also discourages weed growth and enhances the appearance of the space.

Installation

  1. Excavate the Area: Remove a few inches of soil to create a level surface.
  2. Lay Landscape Fabric: Place landscape fabric over the excavated area to prevent weeds.
  3. Add Gravel or Crushed Stone: Spread a layer of gravel or crushed stone over the fabric, ensuring even coverage.

3. Vapor Barrier

Benefits

A vapor barrier helps prevent moisture from rising from the ground and affecting your deck. This is particularly useful in areas with high humidity or frequent rainfall.

Installation

  1. Clear the Area: Remove debris and vegetation from under the deck.
  2. Lay the Vapor Barrier: Spread the vapor barrier material across the ground, overlapping edges to ensure complete coverage.
  3. Secure the Barrier: Use rocks, bricks, or landscape staples to keep the barrier in place.

4. Mulch

Benefits

Organic mulch can help absorb excess moisture and prevent mud from forming under your deck. It also adds a natural look to your outdoor space.

Installation

  1. Clear the Area: Remove debris and vegetation from under the deck.
  2. Lay Landscape Fabric: Place landscape fabric to prevent weeds.
  3. Spread Mulch: Apply a layer of mulch evenly over the fabric.

5. Under-Deck Drainage Systems

Benefits

For decks with slightly more clearance, under-deck drainage systems can effectively manage water runoff and keep the area dry. Additionally consider building waterproof under deck storage.

Installation

  1. Choose a System: Select an under-deck drainage system suitable for low-clearance decks.
  2. Install According to Instructions: Follow the manufacturer’s instructions for installation, ensuring all panels or channels are properly secured.
  3. Redirect Water: Ensure the system effectively redirects water away from your deck’s foundation.

Conclusion

Properly managing the area under your low deck is crucial for maintaining its structural integrity and usability. By using materials like landscape fabric, gravel, vapor barriers, mulch, or under-deck drainage systems, you can keep the space dry and clean.
