  • Can a pergola be made fully waterproof?

    Yes, a pergola can be made fully waterproof by installing solid or translucent roofing materials such as polycarbonate sheets, metal panels, or a sealed insulated roof. Some designs also incorporate retractable waterproof canopies for flexibility. Waterproofing transforms your pergola into a usable outdoor area year-round, protecting against rain while still allowing natural light. Proper installation, guttering, and roof pitch are important to ensure effective water runoff and long-term performance, especially in areas with heavy rainfall.

  • Can decking be built on sloped or uneven ground?

    Yes, decking can be constructed on sloped or uneven ground using elevated supports such as stumps or adjustable steel piers. This approach allows builders to create a level surface without the need for extensive excavation. It’s especially useful for creating usable space on challenging sites or properties with inclines. Proper planning and structural engineering ensure safety, stability, and compliance with local building regulations. Decking on sloped ground also provides the bonus of improved airflow and drainage underneath.

  • What’s the typical lifespan of a timber deck with regular maintenance?

    With regular maintenance, a well-built timber deck can last 15 to 30 years, depending on the type of wood and exposure to weather. Hardwood options like Merbau and Spotted Gum tend to last longer than softwoods. Maintenance should include annual cleaning, resealing or oiling every 1–2 years, and timely repairs. Protecting the deck from standing water and sun damage will greatly extend its lifespan. Choosing quality materials and proper installation are also key to long-term durability.
