Our Services


With more than 30 years in the industry, Boulder Wall Constructions are true experts in structural rock retaining walls. As a specialist rock retaining wall contractor, we are able to design and construct walls up to 10 metres high.

We are proud to have been operating our own extractive quarries sourcing a variety of rock material for more than 20 years. We have operated quarries all over Queensland inlcuding Warwick, Yangan, Maroon, Rockhampton, Helidon, Gladstone, Trade Coast and Swanbank.


Boulder Wall Constructions owns and operates a fleet of six truck and trailers, with six permanently sub-contracted truck and trailers. They are serviced and maintained in house by our own mechanics, allowing us to maintain the highest level of quality control and ensuring the safe operation of our fleet at all times, whilst reducing down time.


BWC operates a fleet of heavy machinery ranging in size from 8 tonnes to 60 tonnes, enabling us to complete any size project for our clients. Our fleet includes excavators, rollers, dozers, loaders, reclaimers, water trucks and graders that are serviced and maintained in house.

Disaster Recovery

Following both the 2011 and 2013 Queensland Floods, Boulder Wall Constructions worked in the most flood ravaged areas helping to clear debris and assist with the clean up. We were further able to assist with the clean up following Cyclone Marcia in Rockhampton in 2015.

Rock Supply

Boulder Wall Constructions began sourcing its own rock when finding a consistent, quality rock supply externally proved extremely difficult.
