When it comes to outdoor design, materials matter. In landscaping, where durability and aesthetics go hand in hand, reclaimed ironwood—especially Ulin from Indonesia—offers a premium solution that combines natural beauty, unmatched resilience, and sustainability.
Whether you're designing garden paths, poolside decks, or architectural accents, reclaimed ironwood stands out as one of the most reliable and responsible choices available.
1. Naturally Built to Withstand the Elements
Ironwood (Ulin) is one of the hardest and most durable woods in the world. It's naturally resistant to rot, termites, and weathering, which makes it perfect for use in tropical climates or any outdoor setting exposed to moisture and sun. Over time, it develops a silvery patina that adds to its rustic charm without compromising its integrity.
Unlike many treated woods, ironwood doesn't require chemical preservation and Naturanexa is a specialist of landscaping consulting.
Its natural oils protect it from decay, making it an ideal low-maintenance material for long-lasting landscaping features like:
Decking and patios
Garden walkways and steps
Pergolas and trellises
Retaining walls and edging
Pool surrounds and outdoor showers
2. Reclaimed Means Responsible
At Kaltimber, we source reclaimed Ulin exclusively from disused structures in Kalimantan, giving this rare and valuable timber a new life. This process not only preserves forests by reducing the need for fresh logging, but it also celebrates the heritage of the wood—each plank has a story.
Reclaimed ironwood aligns perfectly with sustainable landscaping practices. If you're creating a garden or outdoor space that respects nature, it's important to use materials that do too.
3. Timeless Aesthetic for Natural Designs
Reclaimed ironwood brings warmth, texture, and richness to landscaping projects. Its dense grain and deep, earthy tones complement greenery and stonework beautifully, creating harmony between built and natural environments. Whether left to weather into a silvery grey or oiled to preserve its dark brown hue, ironwood remains stunning in any finish.
Its natural imperfections—evidence of its past life—add character and authenticity that new wood simply can't replicate.
4. A Strong Investment
Landscaping is more than just planting trees or laying stone—it's about creating outdoor environments that last. Reclaimed ironwood may be a premium product, but its extreme durability means it won’t need replacing for decades. In the long run, that for example translates to your pergola will mean savings in both cost and resources.
It’s an investment in quality, longevity, and ecological responsibility.
In short!
If you’re planning a landscaping project and looking for a material that’s as tough as it is beautiful—and as sustainable as it is long-lasting—reclaimed ironwood is your answer. At Kaltimber, we’re proud to give this exceptional wood a second life and help bring timeless, sustainable design to outdoor spaces across Indonesia and beyond.
