Why Choose Garapa for Dock Decking
Garapa dock decking makes real hardwood dock construction accessible for freshwater lake and river projects where budget matters. At the most affordable price point among exotic hardwoods, Garapa dock boards deliver genuine tropical hardwood performance — natural rot resistance, splinter-free surfaces, zero chemical leaching — for dock builders who would otherwise default to pressure-treated pine or composite.
The golden-yellow to blonde tones create a bright, inviting dock surface that complements lakefront properties and waterfront homes beautifully. Where darker woods can make a dock feel heavy, Garapa's light color opens up the space — especially effective on smaller residential docks and private boat launches.
At 1,630 Janka — nearly five times harder than pine — Garapa dock lumber provides genuine hardwood structural strength. Natural rot and insect resistance delivers a 30+ year dock lifespan without any chemical treatment. For freshwater dock applications, Garapa performs reliably season after season. Note: for saltwater or heavy marine borer exposure, Ipe or Cumaru are better choices — Garapa is the freshwater specialist.

Garapa's moderate density makes it easier to cut and install than denser species. Best suited for freshwater applications.

Garapa Dock vs Pressure-Treated Dock
Garapa lasts 30+ years vs 10-15 for PT. No chemicals in your lake. No splinters. Better appearance. While Garapa costs more upfront, it eliminates 1-2 dock replacements over 30 years.
Garapa Dock vs Ipe Dock
Ipe is much harder (3,684 vs 1,630 Janka) with excellent saltwater performance. Garapa is the affordable freshwater alternative — real hardwood at the most accessible price. For saltwater docks, choose Ipe or Cumaru.

Cedar is the traditional affordable dock wood, but it's soft (350 Janka), splinters easily, and lasts only 15-20 years. Garapa at 1,630 Janka is nearly 5x harder, splinter-free, and lasts 30+ years — a significant upgrade for a modest price increase.
