Dindas has built a reputation as a leader in timber treatment. We apply innovative technology to all products, giving us a remarkable competitive advantage.
Dindas Australia has set the standard in reliability, customer value, and quality for light organic solvent preservative (LOSP) treated timber. Our comprehensive range of treatment classifications caters to both solid pine and engineered timber, including:
No Drying Process Required
Unlike water-based pressure treatments, our LOSP treatment does not increase the timber’s moisture content. This means no additional drying is required post-treatment, allowing the timber to maintain its original size, shape, and strength grading.
Fast Turnaround and Cost-Effective
Our LOSP process enables rapid order fulfilment, eliminating the need for large storage and drying facilities. This translates to a reliable, cost-effective solution for our customers.
Dimensional Stability
The consistent moisture levels maintained during and after LOSP treatment ensure dimensional stability, making it ideal for the precise tolerances required in engineered timber products.
Versatile Applications
Our treatment varies in colour, with the H3 option being the only clear, durable choice on the market. This exclusive clear coat preserves the natural tones of timber, making it perfect for visible applications.
Partnership for Excellence
Treatments used by Dindas are supplied by our chemical partners, Koppers Performance Chemicals. We benefit from their regular specialist audits, ensuring the quality and consistency of the treatments applied to our wide range of products.
By choosing Dindas Australia for your LOSP timber treatment needs, you invest in a solution that combines tradition, innovation, and unparalleled expertise.
From architects and building designers to landscapers and homeowners, you can rest assured that when specifying timber from the treated range for all structural, outdoor, and above-ground building needs.
Dindas Australia’s standard LOSP timber treatments feature a coloured dye coating for treatment range identification and tracing purposes. For optimal results, it is recommended to use acrylic coating options, as the dyes can bleed through many paints and decorative finishes.
All LOSP Timber treatments offered by Dindas Australia feature a specially formulated water-repellent resin and wax system. This solution reduces water absorption during construction, enhancing the timber’s dimensional stability.
Always refer to the label of your finishing product and follow the manufacturer’s instructions for optimal results.
Our commitment to customer satisfaction and product excellence ensures that you always get the best results.
You can confidently use fasteners and hardware that comply with building codes for their intended use. LOSP H2 treatments do not increase the corrosion risk of fixings and fittings, ensuring safety and durability.
Dindas Australia guarantees that their H2F and H2 treated EWP are protected against structural damage from termite attacks for 25 years. However, H2F is specifically designed to protect against termites in areas south of the Tropic of Capricorn, while LOSP H2 is designed for areas north of the Tropic of Capricorn. In Queensland, the Tropic of Capricorn passes through the Rockhampton city area.

LOSP (Light Organic Solvent Preservative) timber treatment is a specialised process used to protect timber against damage from termites, borers, and fungal decay. This treatment ensures long-lasting durability while maintaining the dimensional stability of the timber.
LOSP Timber Treatment involves using a solvent-based preservative to penetrate the timber. Unlike water-based treatments, it does not add moisture to the wood, preserving its original size, shape, and strength grading.
Yes, LOSP-treated timber is safe for use in construction and other applications. Dindas Australia uses Koppers Performance Chemicals to ensure compliance and safety. LOSP treatments are non-corrosive to nails and fittings that meet building code standards.
Yes, you can paint LOSP-treated timber. However, ensure the timber is fully dry before painting. Use industrial alkyd-based primers or consult paint manufacturers for compatibility. Acrylic primers may not always be suitable, so it’s important to follow product guidelines.
No, LOSP-treated timber is not suitable for ground contact. It is designed for above-ground applications such as framing, decking, weatherboards, and other structural and outdoor uses. For in-ground applications, other treatments may be more appropriate.
The LOSP process involves immersing the timber in a preservative solution containing solvent-based chemicals. This ensures deep penetration without increasing the wood’s moisture content, eliminating the need for a drying period. The treatment is designed to provide enhanced protection from termites, borers, and decay, as well as water repellency.
LOSP and CCA (Copper Chrome Arsenate) treatments cater to different needs. LOSP is ideal for above-ground and appearance-grade timber, preserving the natural look and dimension of the wood. CCA, on the other hand, is suited for more heavy-duty applications, including in-ground use. LOSP treatments are often preferred for engineered timber and projects requiring precise tolerances.
You can find and trust the LOSP Timber Treatment services through Dindas Australia.

I-joists are meticulously engineered using a combination of high-quality materials to ensure strength and durability. The manufacturing process involves bonding a top and bottom flange, typically made from laminated veneer lumber (LVL) or solid wood to a web made of oriented strand board (OSB) or plywood. This construction forms an “I” shape, which provides superior load-bearing capacity and enhanced stability, making them ideal for floor and roof systems.
Yes, Dindas I-Joists can be effectively used as rafters in various construction projects. Their engineered design allows for exceptional strength and versatility, making them suitable for residential and light commercial roofing applications.
