Public Warning - Dylan Trengrouse / Sunline Concrete Pty Ltd

15 June 2016

This is a warning by the QBCC Commissioner to the public under section 20J(1)(h) of the Queensland Building and Construction Commission Act 1991

The Queensland Building and Construction Commission (QBCC) is urging consumers, contractors and suppliers to exercise extreme caution in their dealings with Dylan Trengrouse, previously trading as DNA Concreting Solutions, First Class Concreting Solutions and a former director of Sunline Concrete Pty Ltd.

A public warning was previously issued against Mr Trengrouse and Sunline Concrete Pty Ltd on 10 October 2013.

Mr Trengrouse does not hold a QBCC licence and is not able to carry out or enter into contracts to carry out building work in Queensland. However, he allegedly continues to undertake building work, including concreting work, without holding a QBCC licence.

In February 2014, Mr Trengrouse and the company Sunline Concrete Pty Ltd were convicted of carrying out unlawful building work and fined in excess of $25,000.

The QBCC warns all persons who deal with Mr Trengrouse to exercise extreme caution and seek legal advice before entering into contracts or making any payments, in order to protect their interests.

The QBCC urges home owners to conduct research before engaging contractors, and recommends engaging a licensed contractor even for small jobs.

If you are in doubt as to whether the entity you are contracting with is licensed or holds the correct licence to do the work, please conduct a free online licence search at or call the QBCC (24/7) on 139 333.
