Greenheart wood

Greenheart is a premium hardwood species, primarily sourced from the tropical rainforests of South America, particularly Guyana and Suriname. Greenheart wood is highly valued for its exceptional durability, with a lifespan of up to 60 years even in harsh marine environments. This longevity is a significant advantage compared to other wood species that often deteriorate much faster in similar conditions.

Greenheart wood

Greenheart lumber can be recognized by its heartwood, which varies from light to dark olive green. The sapwood is pale yellow to green and is clearly demarcated from the heartwood. The wood has a fine and uniform texture with a straight to wavy grain and a lustrous appearance.

Applications of Greenheart wood

What is Greenheart wood used for? Greenheart is known for its exceptional resilience to constant tidal loads and saltwater environments, making it a premier choice for heavy constructions and marine applications. Its outstanding durability, strength, and resistance to marine borers position it as an ideal timber for civil engineering, hydraulic works, and industrial projects, such as:

  • Coastal Defence / Groynes
  • Piles (round or square)
  • Industrial floors
  • Lock gates

Greenheart excels in marine environments where its resistance to decay, fungi and marine borers is crucial. The wood's ability to withstand heavy loads, wear, and harsh conditions makes it ideal for structural elements in marine construction and industrial settings.

A sustainable choice

With a lifespan of up to 100 years when fully submerged, Greenheart showcases remarkable natural resistance to decay and insect attacks, making chemical treatments unnecessary and minimizing environmental impact. This exceptionally durable timber's longevity in harsh conditions ensures an extended service life and creates opportunities for repurposing. After its initial use, Greenheart wood can often be reclaimed for various applications. This ability to have a "second life" maximizes the wood's value throughout its lifecycle, making Greenheart an excellent choice for environmentally conscious projects.
