Retaining walls need to be strong to withstand the weight of the soil it’s holding. The compressive strength of the concrete used in our blocks is up to 40MPa. That’s why councils, developers, and engineers rely on our retaining wall systems that are 100% termite and rot proof, engineered to meet and exceed Australian Standards.

“I have had the pleasure of working with the team at Loc-a-Bloc since 2009 for retaining walls and general concrete construction works on various residential and industrial subdivision projects as well as public parks, with the main area being the construction of Gregory Hills Estate for DARTWEST Developments Pty Ltd. Loc-a-Bloc have always been very responsive to the clients needs and work in an efficient, prompt and courteous manner on-site. This often includes working around other construction and services contractors on-site in professional manner to achieve the desired construction program and in the end client satisfaction. I look forward to working with the Loc-a-bloc team on future projects.” – Rod Rixon Civil Engineering & Haulage Contractors
