Why Choose Ipe for Boardwalks
Ipe boardwalk lumber is the proven standard for public infrastructure boardwalks across America. Atlantic City's legendary boardwalk, Coney Island's iconic promenade, and hundreds of municipal boardwalks from the Gulf Coast to New England use Ipe because no other material delivers 75+ years of splinter-free, maintenance-free performance under millions of footsteps per year. When a city engineer or parks director specifies boardwalk lumber, Ipe is the benchmark all others are measured against.
At 3,684 Janka hardness — the highest of any commercially available boardwalk wood — Ipe boardwalk decking resists the constant abrasion of heavy foot traffic that destroys softer woods in a decade. Dense tropical hardwood naturally meets ADA friction coefficient requirements for slip resistance when wet, providing safe footing on beach boardwalks, wetland crossings, and waterfront promenades where moisture is constant. The surface stays splinter-free for the life of the installation — critical for public spaces where barefoot pedestrians and liability are concerns.
Ipe boardwalk lumber requires zero chemical treatment, which means zero CCA, ACQ, or copper leaching into wetlands, marshes, nature preserves, and waterways. This dramatically simplifies environmental permitting for boardwalks through ecologically sensitive areas — a major practical advantage for municipalities and parks departments. Class A fire rating meets wildland-urban interface codes for boardwalks in fire-prone regions.
The lifecycle cost argument closes the deal for municipal decision-makers: one Ipe boardwalk outlasts 4-5 pressure-treated boardwalks over the same 75-year period. Each PT replacement cycle costs the municipality not just materials and labor, but also public disruption, permits, environmental review, and lost revenue from closed facilities. An Ipe boardwalk eliminates all of that — build it once, and it serves generations.

Boardwalk Installation & Engineering Notes
Joist spacing: 16" OC for 5/4 boards, 12" OC for 2x boards and heavy commercial boardwalks — verify with structural engineer for public projects. Board direction perpendicular to travel for best visual effect and structural span. Leave 3/16" gaps standard; slightly wider for beach boardwalks to allow sand drainage. 316 stainless steel fasteners mandatory for coastal; 304 acceptable inland. ADA compliance: consistent surface, no gaps wider than 1/2", dense hardwood naturally meets friction coefficient requirements. Helical pile substructure for wetland boardwalks minimizes environmental disturbance. Seal all cut ends. Acclimate 7-14 days on-site.

Ipe Boardwalk vs Pressure-Treated Boardwalk
PT boardwalks last 10-15 years and require 4-5 replacement cycles over the lifespan of one Ipe boardwalk. Each replacement means public closure, construction disruption, environmental review, and new permitting. PT splinters badly, becomes dangerously slippery, and leaches chemicals into wetlands. Ipe eliminates all of these issues for 75+ years.
Ipe Boardwalk vs Composite Boardwalk
Composite gets dangerously hot in sun — a serious issue on exposed boardwalks. It sags under heavy foot traffic, sheds microplastics into sensitive habitats, and lasts only 15-20 years. Ipe stays moderate temperature, handles any traffic load, and is 100% natural with zero microplastic pollution.
Ipe Boardwalk vs Cumaru Boardwalk
Cumaru delivers comparable boardwalk performance at 30-40% lower cost. For municipalities with tight budgets, Cumaru is the smart alternative. Choose Ipe for maximum lifespan and the proven track record that satisfies engineers and specification committees.
