Cumaru Dock Decking

Cumaru dock decking is the smart choice for dock builders who want premium marine-grade hardwood without the premium Ipe price tag. Brazilian Teak at 3,330 Janka and 65 lbs/ft³ density delivers marine performance that's virtually indistinguishable from Ipe for dock applications — at 30-40% lower cost per board foot. For large dock projects where material volume is high, the savings are substantial.

Cumaru dock boards provide the same critical advantages that make tropical hardwood superior to pressure-treated lumber for marine use: natural resistance to rot and marine borers, zero chemical leaching into waterways, splinter-free barefoot safety, and excellent wet slip resistance. A Cumaru dock is environmentally clean — no CCA, ACQ, or copper entering your lake, river, or coastal water.

At 3,330 Janka, Cumaru dock lumber has more than enough structural strength for residential boat docks, commercial marinas, fishing piers, and waterfront walkways. The warm reddish-brown to golden-tan tones create a beautiful dock surface that weathers to silver-gray naturally. A Cumaru dock lasts 50+ years in marine environments — 3-4 times longer than pressure-treated lumber.

For dock builders comparing Cumaru vs Ipe, the practical difference on a dock is minimal. Both naturally resist marine borers and rot. Both provide splinter-free, slip-resistant surfaces. Both require no chemical treatment. Cumaru is the best-value dock wood that doesn't compromise on marine durability.
