Challenges
Specified Use of Karri Timber. The client requested Karri timber, which is limited in availability, increasingly expensive, and prone to warping with age and weathering.
Environmental and Ecological Impact. Karri is sourced from old-growth forests in Western Australia’s South West region—ecosystems that are vital habitats for native fauna, insects, and birds. Protecting these forests is essential for conserving unique native species and supporting regional tourism.
Material Limitations. Karri timber is susceptible to termite infestation and degradation over time.
Solutions
Proposed LVL Replacement. Castech Solutions recommended replacing Karri timber with Laminated Veneer Lumber (LVL.
Material Suitability. LVL is a proven material used in demanding applications such as concrete formwork beams.
Compliance Assurance. LVL complies with AS1577. Independent testing can be arranged to verify compliance with other codes if required.
Key outcomes & benefits
LVL offers a number of advantages for structures:
Laminated for strength, dimensional stability, and durability. LVL provides superior strength-to-weight ratio and consistent performance, ensuring reliable support for large spans and heavy loads.
Consistent quality. Engineered to be free from natural defects, LVL delivers predictable results every time.
Available painted or unpainted. Customisable to suit specific project needs.
Environmentally responsible, sustainable, plantation sourced. Reduces reliance on old-growth forests and supports sustainable forestry practices.
Competitively priced and readily available. More cost-effective and accessible than limited-supply timbers like Karri.
Material is straight and will remain straight. Resistant to warping, twisting, and splitting.
Will resist water and insect damage. When properly treated, LVL is highly resistant to termites and moisture-related issues.
Saves Western Australia’s old growth Karri Forests and associated Fauna habitats. Supports conservation and biodiversity.
Can be delivered within 10 weeks! Fast turnaround for project timelines.
