About Us


M.B. Pre-Fab was established on 5th September 1977, through a need for good quality wall frames, roof trusses and an unquestionable backup service. The company started in rented premises in Belmont with one employee. That employee is still with us today.

Over the next six years the Company’s reputation and business grew to such an extent that we had to look for larger premises. New premises were located two kilometres away in Leather Street and within three years we had purchased the adjoining factory to house the wall framing section. A few years later the corner block was purchased as a storage yard and in 1995 a third factory was built to house the most advanced fully computerised, automated saw available in Australia. An advanced multi-head auto plate feed jig was also introduced. Some $695,000 was invested to assure quality of products at a cost effective price.

In 1996 Longreach Floor Trusses were introduced with astounding results. M.B. saw a need to develop the wall framing division and to keep up with technology. In 2000 M.B. Pre-Fab set up in a purpose built factory across the road with the first fully computerised wall framing division of its kind in Australia, assuring that quality controls are met and prices remained competitive.

In 2003 MB Pre-Fab purchased a further 3 blocks of land in Leather Street to the West side of the existing office block. Three one acre blocks in Tanner Street, North of the existing factories were also purchased.

During 2004-05 MB Pre-Fab built two new factories approximately 50 metres x 36 metres. One houses the truss manufacturing division and the other wall manufacturing. The wall frame division was relocated to the new wall factory so that the whole business was operated from the one site. East of the offices a new timber shed has been completed.

In 2010 our Estimating and Designing area was extended along with the addition of a training room. The latest Hundegger saw was purchased for the factory to ensure cutting accuracy and to meet our production requirements.

In December 2018 M.B. Pre-fab was acquired by the Big River Group and is now known as Big River Trade Centre – Breakwater.

Although situated in Geelong, Big River Trade Centre - Breakwater delivers throughout Melbourne, Central Victoria, North Eastern Victoria.


Big River Group’s aim is to continue to develop their working relationship with their builders, look for different and improved technology for a higher standard of quality control and manufacturing processing. Service is and will still be our priority to our clients.


Big River Trade Centre – Breakwater’s involvement with community projects has been extremely strong. Local charities such as River’s Gift, Lions Club, Give Where You Live and others have M.B.'s support and where possible this support will continue in the future.
