Timber decking extensions for existing concrete patios
Many Tauranga homes feature small, dated concrete patios that restrict your outdoor living space and create an awkward, uninviting transition from inside the house to the back lawn.
A timber decking extension for existing concrete patios is the perfect way to expand your entertainment area and modernise your backyard layout. Klinks specialises in overlaying tired concrete surfaces and extending them into wide, level timber decks.
Our experienced team ensures the new timber sub-frame is securely anchored, perfectly level, and beautifully integrated with your existing home layout for a flawless finish.
Seamless Integration and Craftsmanship
Building a timber deck over and past an existing concrete pad requires managing tight clearances and shifting ground levels. Our builders utilise practical, proven techniques to ensure the old concrete pad and the new lawn extension blend into one cohesive, rock-solid platform:
Low-Profile Sub-Frame Layouts: Installing timber over old concrete requires careful management of clearance heights to match your home's interior floor level. We use specialised low-profile timber joists or structural deck pedestal systems directly over the concrete, keeping the final decking surface perfectly level while allowing rain to drain away cleanly.
Stable Ground-Extension Anchoring: The most critical part of extending a patio is merging the rigid concrete section with the new lawn extension. We construct a robust timber sub-frame, anchoring deep into the surrounding soil with treated timber posts, tying it directly to the concrete base to prevent any uneven settling or shifting between the two zones.
Damp-Proofing and Ventilation Protection: Placing timber close to old concrete can trap ground moisture, accelerating decay if left unprotected. We install high-performance damp-proof membranes between the concrete and the new timber bearers, alongside strategic ventilation gaps, allowing proper airflow to keep your new extended sub-floor dry and sound.
