Why Choose Ipe for Dock Decking

Ipe dock decking is the gold standard for marine construction. NYC's Coney Island boardwalk, the Atlantic City boardwalk, and countless commercial marinas from Maine to Florida rely on Ipe because no other wood survives saltwater environments like Brazilian walnut. At 3,684 Janka hardness with 69 lbs/ft³ density, an Ipe wood dock delivers 75+ years of service in the harshest marine conditions — constant water contact, splash zones, submersion cycles, salt spray, UV bombardment, and freeze-thaw.

What makes Ipe the best wood for boat docks is its natural resistance to Teredo worms and Limnoria — the marine borers that destroy pressure-treated lumber in saltwater within 5-10 years. Ipe's natural oils and extreme density create a barrier these organisms cannot penetrate. No chemical treatment is needed, which means zero CCA, ACQ, or copper leaching into your waterway. This matters critically for environmental permits, fish habitats, and marine wildlife — an Ipe dock is the environmentally responsible choice for any waterfront.

Ipe dock boards provide a splinter-free, barefoot-safe surface with excellent wet slip resistance. Dense hardwood maintains good traction even when constantly wet — unlike pressure-treated pine that becomes dangerously slippery with age and algae growth. The surface stays cooler than composite and PVC alternatives that become painfully hot in direct sun. For a dock where people walk barefoot in swim gear, this daily comfort matters.

The structural strength of Ipe dock lumber handles everything a marine environment demands: heavy boat traffic, equipment loads, crowd loading on commercial piers, and decades of wave action. The 75+ year lifespan means an Ipe dock is typically the last dock you'll ever build — while pressure-treated docks need replacement every 10-15 years in marine settings.

Dock Installation Tips for Ipe

Use 316 stainless steel fasteners — mandatory for marine/saltwater (not 304). Joist spacing: 16" OC standard, 12" OC for heavy commercial or 2x boards. Leave 3/16" gaps between boards for drainage and debris clearance. Pre-drill all holes with carbide bits. Seal all cut ends — critical in marine environments where moisture intrusion is constant. Acclimate 7-14 days on-site before installation. Ipe dock boards work on wood pile, steel pile, aluminum frame, and concrete substructures. No chemical treatment needed — a key advantage for waterway compliance.

Ipe Dock vs Pressure-Treated Dock

PT lumber lasts 10-15 years on docks — Ipe lasts 75+. PT splinters badly, becomes slippery, and leaches CCA/ACQ chemicals into your waterway. Ipe is splinter-free, slip-resistant, and chemical-free. Over 50 years, an Ipe dock costs less because PT requires 3-4 complete replacements.

Ipe Dock vs Composite Dock

Composite dock boards get extremely hot in sun, sag under load, lack structural strength, and shed microplastics into waterways. Ipe stays moderate temperature, carries any load, and is 100% natural. Composite docks last 15-20 years; Ipe lasts 75+.

Ipe Dock vs Cumaru Dock

Cumaru delivers 90% of Ipe's marine performance at 30-40% lower cost. For large dock projects, the savings are substantial. Choose Ipe for maximum lifespan and proven saltwater track record; Cumaru for best value.

Ipe Dock Decking FAQ

Ipe is widely considered the best wood for boat docks. Its 3,684 Janka hardness, natural marine borer resistance, and 75+ year dock lifespan are unmatched. Proven on commercial boardwalks and marinas from coast to coast.

An Ipe dock lasts 75+ years — even in saltwater marine environments. This is 5-7 times longer than pressure-treated lumber docks, making Ipe the lowest total cost option over the life of the dock.

Yes. Ipe has documented resistance to saltwater marine borers (Teredo worms, Limnoria) that destroy other woods. It's been proven on major saltwater boardwalks and commercial marinas for decades.

Excellent resistance. Ipe's natural density (69 lbs/ft³) and oil content create a barrier that marine borers cannot penetrate — no chemical treatment needed. This is one of Ipe's most important advantages for dock construction.

No. Dense Ipe provides excellent wet traction — better than pressure-treated pine, which becomes dangerously slippery with age and algae. The tight grain structure of Ipe resists algae buildup that causes slipping on softer woods.

No. Unlike pressure-treated lumber (CCA, ACQ), Ipe requires no chemical treatment. Zero chemicals leach into your waterway — critical for environmental permits, fish habitats, and marine wildlife protection.

5/4x6 is the most popular for residential and commercial docks. 2x6 is used for heavy commercial marinas and public piers. 1x6 works for lighter residential lake docks. 5/4x4 is ideal for narrow finger piers.
