The Sawmill

A state of the art, family owned and managed sawmill

One of the most modern treatment plants in Australia.

Located in the rural southwest Sydney suburb of Werombi, the Hayters Timber & Paving sawmill is one of the most modern treatment plants in Australia. A pioneer of timber milling in Australia, Richard Hayter built the first saw bench at the Werombi facility in 1968 and slowly over the years developed the sawmill. In 1975, the Hayter family expanded the mill to sell sawn hardwood building timber, followed by softwood in the mid 1990s.

All Hayters timber is responsibly sourced from various state and private forests, ensuring the timber we provide you has been responsibly grown for the sustainability of the plantation.

From hardwood to softwood

In 1994, as hardwood became more difficult to obtain and the mining industry started to decline, it was decided to make the switch to milling softwood. Radiata pine was sourced from Oberon and Canberra, and demand for the product soon outstripped supply. Further improvements were made to the mill with the installation of a state-of-the-art multi saw in 1998, increasing production from 75 cubic metres of sawn timber a week to 250 cubic metres. With its use of up to five blades, the multi saw could cut up to five different sizes in one pass with laser accuracy. In the early 2000s, the original bench saw, which had been built by Richard way back in 1968, was replaced by another recovery multi saw, enabling a greater range of products to be produced.

Entering the 21st Century

With the introduction of softwood, it became necessary to treat the timber to increase its longevity, so Hayters partnered with chemical company Koppers to treat and sell their timber. However, it wasn’t long before it became clear that it was far better logistically for Hayters to treat and supply its timber in house. In early 2003, in conjunction with the Osmose chemical company (now Koppers Performance Chemical) plans were lodged with Wollondilly Shire Council to build a treatment plant at the Werombi facility. The plant was designed to treat product by both Lifewood CCA and Micropro. Today, the plant treats approximately 20,000 cubic metres of softwood a year.

Timber treatment services

All Hayters Timber & Paving timber products are treated to AS1604, Tuma and TMA requirements.

The Lifewood CCA preservative is a waterborne, Copper Chrome Arsenate (CCA) system that is applied to wood by pressure treatment. Designed to provide long-lasting protection on exposed wood in exterior environments, it preserves and prevents the effects of fungicide, termiticide and other wood boring insects. It is one of the most effective wood preservatives available on the market.

MicroPro is a revolutionary way to pressure treat timber for decks, pergolas, fences, landscaping and general outdoor construction. MicroPro offers many benefits and has earned several green building accreditations in the USA for its environmental credentials which include less energy used in production, greatly reduced greenhouse gas emissions and less release of chemicals into the environment.


Experts in kiln drying

The Hayters Timber & Paving sawmill has a kiln on site to provide wood drying services for all our customers . With over 40 years’ experience in the timber industry, we have developed a controlled and highly stable process that can dry out your timber to help it perform more reliably in your desired application. Whether you’re building a home, erecting fencing or creating a vegetable garden, our kiln dried timber is the best way to ensure the reliability and durability of your structure.

Wood is often used as a building and construction material, acting as a foundation for the structure, but over time, it can absorb and desorb water, causing uneven shrinking. This can lead the wood to become cracked and damaged, making it a poor structural support. Kiln dried wood helps to circumvent these common issues.

The best conditions for wood to be burnt is when it is completely dry, therefore firewood for a wood heating system must contain as little moisture as possible to ensure no energy is wasted on heating water vapours.
