Urban Retaining Walls Team and Equipment

Work With Us

We cover the North Side of Brisbane, Caboolture, Bribie Island and all the way to Gympie.

Family owned and operated

Urban Retaining Walls and Landscaping is a family owned and operated business. We specialise in the design and construction of concrete sleeper retaining walls, fencing installation services using all types of materials from timber to glass, and landscaping services. 

Quality, Safety, Customer Service

Our focus is on quality construction, safety-first and exceptional customer service.

Our company was founded by Company Director Grant Raedel in 2008. After travelling the world, Grant’s passion for building retaining walls, fence construction and landscaping saw him jump on the business idea after he found there was a gap in the market for a dedicated group of retaining wall specialists. Grant’s engineering and construction background saw him team up with a crew of eager followers, keen to help him provide quality fencing and landscaping solutions.


Rather than relying on a team of unreliable sub-contractor’s, Grant designed the business around providing a reliable, trust-based quality service. And so the family moved on in, as every good family does! Soon after starting up, Grant’s father Greg came onboard as office manager, bringing with him his wealth of experience from 30 years owning a landscaping business. Greg enjoys working alongside his family, taking the necessary time to keep them on their toes – as every father does. 

In 2013 Grant’s brother Martin joined the team as Site Foreman after having worked on drilling sites across the country. With a commercial construction background, Martin has ventured from as far away as Karatha, up to Darwin and Northern NSW – before heading back to his home base in Queensland. Experienced in drilling, engineering, landscaping and piling for wind turbines, Martin escaped the hustle and bustle of the mines (and the bush) to join the family business. 

Since moving back from the UK, their sister Karmen, who is a professional photographer, has been responsible for creating the videography and the amazing photos on this website. Karmen has also spent countless hours assisting in the invoicing, quoting and IT setup of the business.

Greg Morris
Senior Civil Engineer
"We have worked with Grant and the team from Urban Retaining Walls on a number of projects requiring very detailed engineering specifications. In all instances the team was able to translate from plan to finished product with professionalism. Their technical expertise is beyond reproach. I would have no hesitation in recommending Urban Retaining Walls for any fencing or retaining wall work. "
Brad Davis

“We are developers who have been constructing residential land subdivisions in the South East Queensland area for over 16 years and have been using the services of Grant and his team for approximately the last 9 years now. They are always the most competitively priced and their quality of work and level of service both before, during and after the job is second to none. Their professionalism is highly appreciated, but most of all they’re a great bunch of people who are easy to deal with.”
