From cracks to discolouration, old concrete patios can be an eyesore. While you can cloak these backyard blemishes with outdoor rugs, fresh coats of stain, or other temporary fixes, building a deck over the concrete is one of the best solutions.<\/span><\/p>\n

Adding a deck over a concrete slab is a permanent fix that can help refine your outdoor space whilst adding value to your house. Additionally, if this renovation is under $20,000, it does not require a registered builder in most parts of Australia, including Melbourne\u2014making a DIY deck a viable option.<\/span><\/p>\n

Whether you\u2019re considering building a floating deck or simply exploring your home improvement options, the guide below takes you from start to finish on how to build a deck over concrete.<\/span><\/p>\n

\"\"How to Frame a Deck Over Concrete<\/span><\/h2>\n

Framing a deck over concrete is done using sleeper panels, also known as sleepers or joists. These strips of lumber sit directly on top of the concrete, are evenly spaced, and run parallel to each other to support the decking boards. Additionally, sleeper panels raise a ground-level deck off the concrete, creating space for airflow and proper water drainage. Both of which are essential for preventing rot and building a long-lasting deck.<\/span><\/p>\n

Building this type of deck framing requires basic woodworking skills, various tools, and materials. But before you go investing in any of those mentioned above, you should analyse your existing concrete to ensure it can adequately support an addition.<\/span><\/p>\n

Analysing the Condition of the Concrete<\/span><\/h2>\n

You want to build a deck that lasts, and your deck is only as strong as its foundation. Therefore, it is essential to assess the condition of your concrete. Is it cracked? Is it shifting? Is it water damaged?<\/span><\/p>\n

While you can<\/span> repair concrete foundations<\/span><\/a> with minor cracks, slabs with extensive damage or evidence of sinking aren\u2019t worth building on. In addition, a damaged base will shift over time, inevitably taking your deck with it, damaging the structure and compromising its safety.<\/span><\/p>\n
