1. Preparation

A. Plan Your Deck

1. Measure and Mark: Use measuring tape and string line to outline the deck area.
2. Check Local Regulations: Ensure your deck design complies with local building codes.
3. Select Base Type: Decide if you're installing on soil or flagstone.

B. Clear the Area

1. Remove any vegetation and debris.
2. Level the area as much as possible.

C. Install Weed Barrier

Lay weed barrier fabric to prevent weed growth. Cover it with a 2-inch layer of gravel for better drainage.

2. Base Construction

A. For Soil Base

1. Excavate: Dig holes approximately 6 inches deep where you’ll place support blocks or posts. Place gravel at the bottom of each hole for drainage.
2. Install Support Blocks or Posts: Use treated wood posts or concrete blocks. Ensure all supports are level using a spirit level.

B. For Flagstone Base

1. Inspect and Level: Ensure the flagstones are stable and level. Fill gaps between stones with sand or mortar if necessary.
2. Place Support Blocks or Joists: Lay timber or composite joists directly on the flagstone. Use rubber pads beneath joists to improve stability and drainage.

3. Install the Frame

1. Lay the Joists: Attach joists to the support blocks or posts, maintaining even spacing (typically 12–16 inches apart). For a soil base, ensure joists do not make direct contact with the ground to avoid water damage.
2. Secure the Frame: Use screws or brackets to secure joists together. Check the frame's level and adjust as needed.

4. Lay Composite Decking Boards

1. Measure and Cut Boards: Measure the deck area and cut boards to size using a saw.
2. Install the First Board: Lay the first board at the edge of the frame. Secure it using fasteners or hidden clips as per manufacturer instructions.
3. Continue Laying Boards: Leave a small gap (3–5 mm) between boards for expansion. Use spacers to maintain consistent gaps.
4. Trim Excess: Trim the edges of the boards to fit the frame.

5. Final Touches

1. Install Fascia Boards: Attach fascia boards to cover the frame for a clean finish.
2. Add Railings (Optional): If required, install railings as per the manufacturer’s instructions.
3. Inspect and Clean: Check the deck for stability. Clean the surface to remove debris or dust.

Maintenance Tips

• Clean Regularly: Use a mild soap and water solution to clean composite decking.
• Inspect for Damage: Periodically check for loose fasteners or damaged boards.
• Avoid Heavy Impact: Do not drag heavy items across the deck surface.
