7 Tips to Prevent Standing Water on Composite Decking

Standing water on your deck is more than just a nuisance. It’s a hazard. Water pooling on decking surfaces can make them slippery, turning a casual stroll across your decking into a precarious slip-and-slide. Plus, standing water can be a silent deck destroyer, inviting mould, mildew and decay onto your beautiful boards.

Luckily, with smart design choices and occasional maintenance, these problems can be avoided. In this article, we discuss how to keep your composite decking free of standing water. Read on to find out how to keep your composite decking pristine, dry and safe.

1. Embrace proper planning and installation

The battle against standing water begins even before your first board is laid. For optimal water management, your deck should feature a slight slope away from your house of 1% – 1.5%. 

At Assured Composite, we understand the importance of precision in deck installation. Our approved traders should install your decking to ensure proper water runoff.

2. Opt for quality composite decking

Not all decking materials are created equal. Composite decking features a blend of wood fibres and recycled plastics for superior resistance to the elements. Unlike traditional wood, composite materials do not warp, crack or swell as easily when exposed to moisture. Our high-quality decking options are designed to minimise water retention to keep your deck safe and looking great all year round especially our Superior and Eliote ranges as they are capped in a polymer protective shell

3. Maintain a strategic gap between boards

Always ensure proper spacing between your decking boards. This gap allows water to flow freely off the deck, rather than accumulate on the surface. The recommended spacing can vary depending on the specific product and environmental conditions, but, generally, a gap of at least 2mm is advised.

4. Regular maintenance is key

While composite decking requires significantly less upkeep than traditional wood, some maintenance is still required to stop water from pooling. Periodic cleaning to remove debris, such as leaves and twigs, that can clog gaps and prevent water flow is crucial. A gentle sweep or a wash with a hose can keep your decking looking pristine and functioning perfectly.

5. Implement effective drainage 

In some cases, especially in areas prone to heavy rainfall, additional drainage may be necessary to keep your deck dry. Under-deck drainage systems, for example, catch water that slips through the decking and channel it away, keeping the area beneath your deck dry and stable.

6. Choose accessories wisely

The right accessories can significantly enhance your deck’s water management. For instance, adding a pergola or awning not only provides shade but also directs rainwater away from your deck surface. 

At Assured Composite, we offer a range of accessories and customisation options that complement our decking materials.

7. Consider professional inspection

Even with the best materials and installation, the unexpected can occur. Regular inspections by a professional can help catch and address any issues that could lead to water pooling, such as blocked drainage or the need for resealing.
