Company History

Mendham Engineering commenced operation in April 1948 under the home of the late Alf Mendham Senior.

Alf Mendham Senior and Sons, Alf, Tom and Jim worked hard to build a business and establish a clientele of garage owners, including truck and bus companies and operators.

In November 1949, the operation moved to a new workshop on the corner of Ipswich Road and Kenway Street, Moorooka. The site preparations, excavation, filling and construction of the workshop were all done by the four partners after normal working hours and during the weekends.

The original workshop was extended several times over the years until, after approximately 22 years, the site was outgrown.

In 1971, a new building was built at 1776 Ipswich Road, and the equipment was moved in. Over the next 38 years, this building was extended until it also was outgrown.

In 1985, Mendham Engineering commenced selling new and used Engine Reconditioning machinery. In 1988, Mendham Machinery commenced trading and took over the sales of New and Used Engine Reconditioning Equipment.

In 2009, a new modern tilt slab purpose-built building was built next door at 1800 Ipswich Road. Mendham Engineering and Mendham Machinery moved to the new building, where Mendham Machinery continued trading until October 2016, when it stopped selling equipment and ceased trading. Its employees transferred to Mendham Engineering Pty Ltd.

In mid-2025 a new larger purpose-built tilt slab building was commenced in Heathwood, and after about a year of construction the company moved all the equipment from Rocklea to the new building in July 2026.

The new building has many benefits and improvements to the previous building which includes not having the threat of the potential flood effect in Rocklea.

In May 1995, Mendham Engineering was accredited by SGS International Accreditation Services for the Quality System based on the requirements outlined in Australian Standard AS/NZS ISO 9002-1994.

In 2000, the system was upgraded to the standard AS/NZS ISO 9001-2000.

In 2017, Mendham Engineering was re-accredited by SGS International to the standard ISO 9001-2015.

In 2023, Mendham Engineering was accredited by SGS International for the additional standards of ISO14001-2015 and ISO45001-2018.

It is the company’s policy to continue to purchase and maintain high-quality machines and to retain a reputation for high-quality work.

We are proud to have a comprehensive list of major supply and repair companies in the Earthmoving, Mining and Trucking industries as account customers.

Today, the bulk of the company’s turnover is directly related to Heavy Diesel Engine and Earthmoving Equipment Repairs.

Since its inception in 1948, Mendham Engineering has been a family-owned company that is presently administered by Doug Mendham with sons Wayne Mendham and Darren Mendham.
