90×22 Pine Decking Ripple WBA

What is WBA treated pine decking?
WBA stands for Wood Biomass Ash, a water-based preservative treatment that protects pine timber against pests and decay in above-ground outdoor applications.

Which way does the ripple face when installing?
The ripple always faces down. The ridged underside creates airflow channels between the board and the substructure, which reduces moisture buildup underneath the deck.

Does this decking need to be oiled before installation?
No, the boards come pre-oiled ffrom the factory which gives them immediate protection from weathering. You will need to apply one final top coat after installation to seal and protect the finished deck surface.

Is WBA treated pine safe for kids and pets?
Yes — this is one of the key advantages of WBA over traditional CCA treatment. The water-based preservative doesn't contain the copper, chrome and arsenate compounds found in CCA treated timber, making it a safer choice for households with children and pets who use the deck regularly.

Can I use this decking for deck stairs as well as the main deck surface?
Yes, this pine decking can be used for deck stairs. Make sure to adhere to local building regulations for slip requirements of steps.

Do I need to seal cut ends after trimming on site?
Yes, always apply a H3 end-grain sealant to any cut ends after trimming. The treatment and factory oil coat protect the outer surfaces of the board, but fresh cuts expose untreated timber at the cut face. Sealing cut ends is a simple step that protects the timber where it's most vulnerable.

How do I maintain my pine deck?
After applying the final top coat of timber oil post-installation, the deck should be re-oiled periodically to maintain its protection and appearance. Once or twice a year is a general guide depending on sun exposure and foot traffic. Clean the deck with a dedicated timber cleaner before each re-oil to remove weathered surface oil and prepare the boards for a fresh coat. Discover more about maintaining your timber deck.

How does WBA treatment compare to CCA treated pine?
Both treatments protect pine against pests and decay in above-ground outdoor applications, but they achieve this differently. CCA uses copper, chrome and arsenate compounds, while WBA uses a water-based formula that's considered safer for people and the environment. For most residential decking applications the performance is comparable. The main reason to choose WBA is the reduced chemical concern, particularly for family homes.

What species of pine is this decking made from?
Pine Decking Ripple WBA is made from Southern Pine (a pinus caribaea/elliottii hybrid grown throughout southern Australia and New Zealand). It's a consistent, well-regarded softwood species widely used in Australian decking and outdoor construction.

Is pine ripple decking suitable for a pool deck?
Pine Decking Ripple WBA is rated for above-ground outdoor use and can be used in poolside applications. Keep up with regular oiling in high-moisture environments like pool surrounds, as softwood pine needs consistent maintenance to perform well in areas with frequent water exposure.

What fixings should I use with pine ripple decking?
Stainless steel fixings are recommended for all outdoor pine decking. Plain steel nails and screws will rust in outdoor conditions, causing staining and eventually compromising the fixing.

How does pine ripple decking compare to hardwood decking?
Pine is lighter, easier to work with and more affordable than hardwood decking options. The trade-off is that softwood pine requires more consistent maintenance (regular oiling and prompt attention to any bare or damaged areas) to match the longevity of a well-maintained hardwood deck. For budget-conscious builds where ease of installation and eco-friendly treatment are priorities, pine ripple decking is a strong and practical choice.
