Our Promise to You

A name you can trust

Boulder Wall Constructions has been operating in the civil construction industry for over 30 years, developing a reputation for quality workmanship and excellent service.

We have worked with some of the biggest names in the industry, with some of these strong working relationships spanning more than two decades.

Safety first

At Boulder Wall Constructions, a commitment to health and safety is part of everyday business. Through strict compliance with statutory requirements, codes, standards and guidelines and the promotion of a positive safety culture within our Company, we maintain a high safety standard across the board.

Our system of supportive, consultative and accountable leadership provides every employee with a safe and healthy workplace environment to ensure that work is carried out in the safest possible manner.

Quality control

Every wall we build over one metre high is designed and certified by a Registered Professional Engineer of Queensland (RPEQ) who works closely with the Company throughout the entire construction process.

To maintain our high operating standards, all staff and contract Engineers are familiar with the Company’s procedures, expectations and quality control measures. This allows us to identify and address any potential problems during construction, preventing many unexpected issues upon completion and resulting in prompt certification.

Total retaining solutions

Boulder Wall Constructions can offer total retaining solutions for your project, with 5 to 25kPa loadings from domestic application to heavy industrial requirements.

In addition, in most cases rock walls can be up to 50% cheaper than other manufactured retaining systems, as well as up to 50% quicker in construction time required.

Consistency and reliability

We take pride in our unique ability to guarantee the quality of our products and services, by managing all aspects of our business internally from rock supply through to delivery and construction.

By running our own quarry operations for some types of rock, we are able to guarantee consistent, quality rock supply. Rock is delivered to site by our own fleet of trucks, then used to construct the walls by our own operators, with quality equipment that is serviced and maintained by our own mechanics.

Unparalelled experience

At Boulder Wall Constructions, we are proud of our team of dedicated and qualified people, committed to our Company and the work that we do.

The skills and experience of our team are the driving force behind our Company, with our entire Management team and many of our employees having been with the Company in excess of ten years. Together our industry experience is unrivalled by any of our competitors.


“As both the developer and the client, we couldn’t be happier with the success of the Brendale project. The finished product looks outstanding. The process from start to finish working with Boulder Walls was smooth and efficient which is invaluable on such a large project. The wall construction was achieved ahead of time and within budget. We are delighted with the achievement of the project and look forward to working together in the future.”
